Took my G8 to the dealer for any oil change and to check other small issues. Told them to check for any updates. On the repair receipt noticed that the dealer did in fact do a ECM & TCM update number 08150. I have to say the G8 does drive alot smoother than before. The throttle tip in is not as jerky as before. Moreover, the shifts have improved dramatically. Feels much more refined in all aspects. I encourage all owners who have not yet done so to go to the dealer and have the ECM & TCM update done ASAP, it will feel like a totally different car. Dealer said my G8 was the first one in ever for service! :gears:

Boy, I really like that color. :p

Man, thats the best news so far. I'll contact my dealer tomorrow and set up an appt.
thanks

Then the '09 should come that way! Sweet!

Just letting a tranny break in can make a huge difference too.

Thanks for the heads up on this. I have my car scheduled for Monday @ 7AM.

How did you find out about the TSB? Is there anywhere to search for them on the web?

My car was manufactured in November, and doesn't show any updates to the PCM or TCM code yet. I also called a local Pontiac dealer and they don't show any updates for my G8 either. Here's what the complete history for my car looks like:

92228514 00007CB7 Part number change only, does not address any service issues.
92225787 0000FA3A New calibration to address customer complaint of bump during active fuel management transitions. Incremental release RPR3.
92221546 00000910 Incremental Release RPR2.
92221176 000019CC New calibration for start of production
92218781 0000AD71 New calibration to correct problem occurring at the assembly plant. Does not address any service issues.
92216984 00007E47 New calibration to correct problem occurring at the assembly plant. Does not address any service issues.

Keep in mind GM's policy.

Important:

• DO NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customer's concern.

I dunno what that GM site is trying to tell me


The site that Re Raise posted will not give the answer that theGeneral has offered to provide.

Re Raise site is the calibration update site.

theGeneral will be checking the GM Vehicle Inquiry System (GMVIS) to see if each of your VINS is one of the cars involved in Service Update 08150 (this thread) for the ECM update or 08090 (previously announced) that deals with the seat belt chimes.

Mine is scheduled for the TCM update at 1030 tomorrow.:gears: Since I bought it back in March and it acts a bit flakey I'm pretty sure it wasn't done before I bought it. They're doing it while they rebalance the wheels and reinstall the amazing floating wheel weights.:banghead:

Apparently, the TCM part is typo. They do not change your TCM with that TSB.

I'm curious too. Here's my vin:

6g2ec57y18l124303

thanks!

I got mine done yesterday and man you can tell the difference more responsive and it doesnt hesitate as much.. I got mine done in like 30 mins. this is what the service invoice says:
Recall V1413 Replace Fuel Sender Harness 615 WGM
1877 Reprogrammed ECM and TCM

6g2ec57y28L134273 is mine. Please let me know.

It does feel better. Not significantly better...but better.

The biggest difference is the throttle tip-in. It doesn't jump off the line with just a touch of the throttle anymore. It'll still pull like a demon off the line, but you need to have your foot into it like you mean it to do so.

The shifting seems a little more sure. It won't make your car feel like it has a shift kit in it or anything, but it doesn't seem to get as confused as before.

Now, whether that's due to the throttle remapping or something they did to the TCM...I'm not sure. I have a theory that the touchy throttle may have been confusing the tranny, kind of giving it mixed signals as to what the driver's intentions were.

Either way, it took 2 hours for them to flash the car for both the ECM/TCM and the passenger chime TSB's.

Was it worth it? As long as I didn't have to pay for it, it was. If this was a flash that I paid for I'd be very disappointed as it didn't really change it THAT much. But, it did help.

here is my vin 6g2ec57y58l988092

MY vin is 6g2ec57y18l133616 I was trying to look at the site that showed the calibrations, but was unable to see if it has been done yet, I would say no at this point. But if someone could check I would appreciate it, thanks.

before i bring mine into the dealer, ill read the stock ECM/TCM with HPTuners. then after they service it, ill read it again to compare.

hopefully we can find out what they changed. :)

curious about mine too, 6G2EC57Y48L988813

Until theGeneral returns to answer specific VINs..........

Here is a rule of thumb:

If you have a 2008 G8 GT and took delivery before the April 23rd announcement of this Service Update, there is a 99% chance your car will need the Update.

Those that have taken delivery after the announcement of the Update, should ask their dealership if it has been performed. As theGeneral has pointed out multiple times, it should have been performed on any car that was in inventory at the time of it's announcement, or arrives after announcemnt and before delivery.

Thanks - now I understand. Bought mine at the end of March, so I'll just have them perform the update when I go in for my first oil change (which is coming up.) Thanks again!

Sorry for the delay. I only come on here when Im at work. lol

I contacted my dealer service department and confirmed that they did, in-fact, perform 08150 on 4/30/08, the day I picked my car up. They did it as part of the PDI process. He said that when he pulls up the GM website, it shows that TSB as still being Open, yet he knows that it has already been done, so there is obviously a delay in getting the data updated. So - if you have just recently taken delivery - assume it has already been done.

As for the sliding wheel weight issue, he told me that they have not seen that issue manifest on any cars yet but wants me to bring it in tomorrow morning so they can re-check the balance of all four wheels and use a better adhesive on the weights. He told me that they have the proper balancing equipment and that the process will take a little longer because of the type of balancing they do - about 1.5 hours.

It actually depends on when they submit the warranty claim. If they are not running a tight ship then they possibly did not submit the claim right away which would not change the status of the campaign being open or closed. Sounds like you're working with a fantastic dealer. :D

That is a good point General - I'm sure that each Dealer submits such claims differently. My car was a courtesy delivery; I ordered it through Enterprise Fleet Leasing who then arranged to have it delivered by my local Dealer - John Bailey Pontiac, Buick, GMC in Buford, GA. I have been very pleased with them thus far. They are a small Dealership in a very rapidly growing area. I think they sell a lot of cars but their facility is still very similar to the way it was years ago - not very modern. However, I think they still know what Customer Service means. I didn't buy this car through them but they are treating me as if I did. So, obviously, they have earned my service and parts business and in all liklihood, my vehicle business too.

BJ

Thanks General, it looks like my G8 needs the 08150 update. I called the stealer this morning and the said that my vehicle doesn't have any TSB's available and that the 08150 that I referenced was for an issue with the horn. Obviously this isn't the case, but I'm sure I'm the weak link here.

Do you know what I should say to them (no sarcastic remarks from other please :)) to convey that I want the update?

Thanks!

Could you please check mine 6G2EC57YX8L118659 Thanks

Hi General,

I checked the website, but wasn't able to determine if the service bulletin was done on my car. I picked the car up on April 18th, can you check my VIN as well? 6G2EC57Y08L129900.

Thanks for your help.

I had this done yesterday and there is no notiecable change in shift behavior. IMO I wouldn't go out of my way to have it done.

No, I wouldn't either... the dealer, however, is required to perform them during your next service visit. (or at least they are supposed to)

FYI - I got mine done today. My shifting seems improved.

My G8 was delivered on April 17, so I got mine done today - both ECM & TCM indicated on Service Update 08150.

The ECM reprogramme updated the main operating system and added several calibrations to address customer complaint of bump during AFM transitions.

The TCM reprogramme ... OS / Transmission / Transmission diagnostic / System (report was not very descriptive)

Can't say I noticed anything different on the ride back home.
Just feel more comfortable that I got it done.

Good job general

Had mine done last week. Noticable differance in acceleration and shifting. The torque managment is not so drastic and almost to the point of being unnoticable. Mine was an 888 car so it probably had the worst tune from the factory.

And this one?

6G2EC57YX8L988752

Hi,

I am picking my car up tomorrow. Could you possibly tell me if the update has been done to it or if I should ask them to do it?

VIN: 6G2EC57Y28L126447

Also, would you be able to tell me when it was built or any other info? Thank you so much for your help. It is greatly appreciated :)

I took my car into the dealer last friday 5/9, the service guy said the only uncompleted update to the car's computer was a passenger seatbelt update. Have there been any new releases since last friday? Thank you.

I have an appointment tomorrow at 9am to get the seatbelt and 08150 updates done.

Picked mine up May 9. What can you tell me about it?
VIN# 6G2EC57Y38L143015
And what SN# would it be? I know its post 888

Thank you, sir!

Just came back from the dealer with the update. Noticeable difference. RPM's are lower and don't have to go up to 3k to get you up to speed. Also, my fuel economy increased about 4 MPG. YAY!

It has probably already been done but I might as well ask, I don't really want to go into my local Pontiac dealer since I didn't buy the car from them, my VIN# is 6G2EC57Y78L143616. Thanks!

if you are thinking about getting a tune in the near future or if you already have one, this is a waste of time....

OK, I am curious now too. Hope I am not the straw breaking the back.....

6G2EC57Y98L139079

if you are thinking about getting a tune in the near future or if you already have one, this is a waste of time....

true but I had to go get my front bumper replaced (due to shipping damage). I figured while they are at it they might as well put in that update until I get the tune. Only took them 10 minutes

if you are thinking about getting a tune in the near future or if you already have one, this is a waste of time....

It is if Vector is doing the tune. Since Vector can do this too. If you are going to do another tuner, have the pcm updated.

My vin # 6G2EC57Y58L135109

Service manager is a buddy, I called and he first said 08150 was a horn update. I gave him hell, and he dug further and found the ECU update. My VIN ends in 5109, he said it only applied to ending #s 7XXX to 8XXX.

Help please. I sure hope there's some kind of update for mine. Mine gets worse all the time (or I'm just getting more frustrated)

Can you check please?

DL

It is if Vector is doing the tune. Since Vector can do this too. If you are going to do another tuner, have the pcm updated.
i'm fairly certain any tuner could do this... i believe this update is just firming up shifts in normal and sport modes...

Before you have any other calibrations/updates/tsb's performed, check this thread http://www.g8board.com/forums/showthread.php?t=2992&highlight=battery as loose terminals can explain a lot.

Just got my update today also! They machanic was cool! He does alot of aftermarket tuning on the side. He said he can retune my car and take the speed limiter off if I wanted! I rode in his G8 that he already retuned and all I can say is WOW!! What a major difference. We where able to get up to 148 mph before he let off! You can feel the car just pulling all the way! Man this car really is a beast!

Took mine in today. The service writer didn't see anything on his computer for it. He said they were slow today so he could get it in and it would take an hour-hour and a half to get it in and see if there were any updates to download from GM. Turns out there were 9 ECM updates but no TCM updates. He said the paperwork would detail what was done, it tells me nothing useful, just that the ECM was updated. I was hoping for a breakdown of what the updates did. It does seem to have smoother throttle response when taking off and will now spin the tires when flooring it from a dead stop with ESP off. Even though no TCM update was done it does seem to shift quicker and smoother in both drive and sport mode. We'll see if it improves the MPG at all like some have claimed.

so can someone check mine it is 6g2ec57y88l136111

I got my recall service done today ECM/TCM and also service passenger seatbelt reminder chime /light.No other recalls ,but did get them to check battery cables and yes they were loose .My car does seem to be running smoother .Tahnks message board ,I dont know how long it would have taken Gm to inform me about racalls!!!!

Took mine in today for an oil change and to get the TCM/ECM flash. The good news is that it seems to shift better and is much smoother on acceleration. The bad news...when I got home I noticed there was a gouge in the lower trim piece on the passenger side. I spent three hours detailing the car yesterday so I know for a fact it wasn't there when I took it in. Makes me sick... It's going to the body shop tomorrow (at the dealers expense, of course).

Just goes to show ya you can't trust anyone with your stuff. Had the update also and now my steering wheel back part plastic thingy won't stay on. pops off every time i signal

post up your vin, or pm me, and I can tell you if it has already been done. It was supposed to be performed when they arrived at the dealerships.

Hey - General... here's my VIN - 6G2EC57Y28L129641

I'd appreciate your feedback on my G8. Thanks for your efforts for posting these updates! :thumbsup:

Had mine updated and it definitely runs smoother. Problem is they also did the seat belt update (which I don't think I needed) and now my driver's airbag light flashes constantly.

Anybody got an answer to this one?Picked mine up May 9. What can you tell me about it?
VIN# 6G2EC57Y38L143015
And what SN# would it be? I know its post 888

Thank you!

Just got my re-flash yesterday. I picked the car up on March 15th so it was an early one and hasn't been back to the dealer until this trip.

Big improvement in shifting for me. No more "deep breath" hesitation when punching it at mid-range speeds. The shifts are firmer but not hard enough to chirp the tires...yet. I haven't had a chance to really open it up but all and all this is quite an improvement from where I started.

General - I hate to jump on this bandwagon adding more weight, but can you check mine as well.

6G2EC57Y68L135555

Well I guess I will throw my VIN into the ring also. I picked mine up on May 3rd. It has been perfect ever since. Maybe they did the update maybe they did'nt. They were preparing my Red GT for the owners wife to drive as a Demo. I drove up saw it and fell in love with it. hour later I was driving it home and I think she was kind of pissed. The salesman said she really wanted it but he said the Owner told him Customers First before family. I thought that was cool.
VIN#6G2EC57Y68L138441

Just let me know when you can if I also need the TCM update. Also thanks in advance...

might as well throw mine into the mix as well...

Until theGeneral returns to answer specific VINs..........

Here is a rule of thumb:

If you have a 2008 G8 GT and took delivery before the April 23rd announcement of this Service Update, there is a 99% chance your car will need the Update.

Those that have taken delivery after the announcement of the Update, should ask their dealership if it has been performed. As theGeneral has pointed out multiple times, it should have been performed on any car that was in inventory at the time of it's announcement, or arrives after announcemnt and before delivery.

Guess should update this thread's May 5th "Rule of Thumb".

New version:

If you have a 2008 G8 GT and took delivery before the April 23rd announcement of this Service Update, there is a 99% chance your car will need the Update.

At some point the car will no longer need the update. Unfortunately, the procedure bulletin doesn't give a clear VIN cutoff.

So something along this should work:

Those that have taken delivery after April 23 of a GT that arrived at the dealership before the Update announcement or shortly after, should ask their dealership (or theGeneral) if the Update has been performed.

Those that have taken delivery after April 23 of a GT that arrived after the Update announcement should ask their dealership (or theGeneral) if the Update is required, and if so has it been performed.

At some point, May arrivals or cars in the 8L136000-8L137000-8L138000 range will not require the update.

OK, I have been perusing the Service & Parts Operation page and I have no idea what the hell I am looking at. From what I can make out of it, I think my car has all of the recent updates and having taken delivery of it in early May probably makes sense. However, just to be sure, here is my VIN # 6G2EC57Y08L139407. If you can, please look this up for me. Thanks in advance!

OK, I have been perusing the Service & Parts Operation page and I have no idea what the hell I am looking at. From what I can make out of it, I think my car has all of the recent updates..........

That can not be determined from the Calibration site.

That can not be determined from the Calibration site.

That might explain why I had no idea what I was looking at. I guess I will just wait to see if theGeneral responds to my query. Unfortunately, I am in China right now so I can't just go to my dealer and ask...

CAN YOU PLEASE CHECK MINE FOR ME?

the general hasn't been around for a awhile...so i think it's a shot in the dark that we'll get a response about our cars...

Just had the update done in the womans car and now the air bag light flashes and won't go off.... The dealer said they didn't know what to do and can't call someone on the weekend so now I only can hope that the airbag doesn't go off when we get in a wreck and I can sue for her getting hurt in a wreck... More damn gas wasted to have to go back and they cancelled the order for the air deflector we have been waiting for 2 months as her clips were broken when she got it new.... What a waste... I wish we would have never had the updates done now.... Not to mention the 3 hours spend wasted also....

For those who went to the dealer and had this done, I bought my car in May. However it was built in 01/08. Now my question is, should the update show as performed in the service history of the car in GM VIS? I was at the dealer today getting an oil change and asked the service writer to look up my car. It had some repair regarding the traction control wiring done (news to me), however it did not show anything listed for this update. My VIN falls in the range according to him, so I'm bringing it back Tuesday and he'll have one of his guys check it out.

Mine did the same thing when they flashed mine. I noticed it before I drove off and they took it back in. The corrective action according to the invoice was "REPROGRAMED SDM".

They noticed it, but weren't sure that an SDM would have fixed it... So they wanted to comfirm with gm/holden first... So I guess when the part comes in for the sun roof, I will have it back in the shop, thanks for the fix, I appreciate it.

Now my question is, should the update show as performed in the service history of the car in GM VIS?

If GM VIS is not showing the update being required, then it is not required on your car.

Well the service writer didn't let me get a good look at the screen, so I don't know where it would have said that, or if it did. He just told me to come back in on Tuesday. The dealer is only a mile or so from my work, so I'll take it in and if it doesn't need it, then the guys can joy ride my car. :)

Nothing showed for my car but when they hooked it up to the computer and checked GM's site for updates there were 7 updates for it.

Then why is the thread titled ECM/TCM UpdateS with an S meaning plural???

No clue. Not a member of the language/typing police. Try asking the site member that opened the thread.

But if they are not around, I would guess that since they asked their dealership to see if their were any "updates", that was on their mind when they started the thread and it's title. As they say in their first post, the dealership found the one update that has been issued and was required to be done to their car.

And I'm just sharing that there may not be "required" updates, but there may be updates available.

Anyone else notice after getting the 08150 ECM/TCM update that you can't do a burnout anymore?

I used to be able to do them with the traction control off (ESP) on a dime, now, nothing......I guess they re-calibrated the torque management after seeing all the rags do their burnouts!!!! :judge:

I wonder what else they did....

Am I nuts, or did this happen to anyone else?

You must be nuts. Mine leave 2 streaks every time I hit the loud pedal.

?? Burnout?? I can only do a burnout if I power brake.

Yes, it's also killing my 60' times.

It is kind of funny, there was no problem before the reprogram, now with the update, she just won't do one, even power braking.

hummm....i'm not entirely sure whether my car has had the tsb 08150 done or not...but just today i easily screeched the tires (with esc on) from a stop; and i only gave her partial throttle...

I can do huge burnouts off the line at part throttle, 19's summer tires, and 93 octane. I wonder if these cars that are having trouble are pulling timing on hot days with 87 octane or 10-15 % ethanol. I have not checked to see if I have the updates, but my car was not delivered to the dealer until June 22.

Do you guys suggest the service update as an immediate trip to dealer? I picked my GT up on 4/13.

If you get a Vector tune all updates are done plus all the necessary performance mods. Heat soak is the G8 enemy. IATs to high take timing out and slow u down alot.

One more reason to install a cold air intake that is open to under hood temps........Wait a minute.....

Roto_Fab seals to the hood. If u block off the inner fender and open the lower panel, waalaa no hot air.

try rolling into the throttle before flooring it...that seems to work better on my car for spinning the tires. if i nail it to the floor from a stop, the tq management kicks in way too aggressively...

Might be helpful to your effort, if you make a post with the approximate highest VIN number you find that requires or had the update.

Then people could compare to their own and it would be possible for them to determine if it is needed.

I got my Dealer ECM update and it now seems my mileage went to crap it could be just me, anyone else have this issue. I have always averaged 18 or so and now im down to about 15.5-16
i guess I will try a full tank and baby the crap out of it and see what I get. I may do 2 wot's per tank of gas.

this is too f'n funny. what do u guys tell the dealer when u took your cars in? i called gm and they said i was due for an ecm/tcm update. when i told dealer that he was dumbfounded

Just tell them to hook it up to the computer and download the latest updates for the car. The service guy at my dealer didn't show anything and didn't know anything about any updates but said they could hook it up and check anyways since they were slow. Turns out there were 9 various updates for it.

negative. Just tell them to plug the last 8 of your VIN into GMVIS. They'll understand and can get the info from there.

i talked to the service manager since i had to drop the car off last night. he said "they just dont hook up the cars for no reason" he said is there a problem. lol. yah the throttle response is ****. he said ok well have a look at it. is this ridiculous or what. ill find out later. for one if i can talk to gm and they show im due for an update why the f cant they. sick of this *****.

Picked up my GT today after having the oil changed and they made the changes to the PCM and TCM. What a difference, much smoother shifting. They asked me the same question about if I had a problem, I told them yes and that was it. Thanks to all for the great information!!!:driving:

Can someone please post the actual service cost they used for the ECM/TCM update? I'm anxious to check out my service dept paperwork to see if its been done. If not, I'll be going over tomorrow.

but this is what sucks about service at most "american" auto maker's dealerships. when i owned a honda several years ago, they automatically would check for service bulletins on the car and update software, or whatever, without even asking when i brought the car in for an oil change. that was nice!!

Yeah, thats what gm intends for dealerships to do... unfortunately not all of the dealers are on par with gm ideals.

i supposedly got it flashed. the work order didnt say much neither did the service manager. oh well getting a tune soon anyways

yeah folks, its a "campaign." They dont need to tell you they did it, as the manufacturer is trying to quietly settle any issues and/or keep one from happening. GM doesnt tell them NOT to tell you, its just something they're expected to do.

I have run up on some dealers that dont check for these, but that's rare. Also, on the first run most of the dealers were supposed to do these before they even left the lots. . .

You can forget about the update fixing that issue (throttle response). The TCM program sucks and only people who got after-market programming were able to lessen the lag in response.

I've been complaining about it to GM and others since I got the car and GM basically says "sorry but that's how it drives".

I have all the updates. I'm going for the tune soon.

What happens to your "Tune" should you take it in for one of these "Campaigns"? Both ECM and TCM but TCM in particular since these seem to be what the campaigns are about. If we have the VMS TCM ugrade will the campaigns effect them?

if you have performed an aftermarket tune it is my assumption that it is "taken care of." As far as I know though, if you bring your car in and their is a campaign (either now, or a year from now) they can overwrite that tune.

just picked up an 08 GT yesterday. was told it had been on the lot for about 3mo. so this update should be done but if you can check that would be great. i gotta go back for an alignment probably next week so if i can kill two birds with one stone, that would be great. 6G2EC57Y28L149890

Campaign Mail Date: 8/19/08
Description: Servuice Update Bulletin INV Only - Auto Trans Delay Downshift

Can anyone provide more detail on this issue? Dealer took care of this before delivering the car to me last week, so I have no idea if there was a difference in shifting after the work was completed.

#08254
Description: Service Update Bulletin Inventory Only - Auto Trans Delay Downshift



Just a Service Update, along the lines of #08150 and #08090 talked about earlier in this thread.

For certain GTs in inventory only.

Similar to the TSB #08-07-30-036 being talked about above, for owners that may comment on delayed acceleration or lack of performance from the automatic transmission when applying throttle at low speeds.

I had an update done last Saturday and same thing with mine, went from an average of 21mpg to 18/19...WTF ?

did it make a difference?

I didn't drive it yet, but my wife noticed it shifted a lot smoother.....there use to be a bad delay on a downshift at lower speeds.

that service bulletin or tsb should be mandatory recall because that delay is gonna cause an accident. it is that noticeable at times...!

Yeah its a little unsettling to know that there are updates like this for our cars and we have to find em out on our own.

I noticed mine has the infamous delay on downshift. Upshifts can be better. Still have 750 miles on it so the car is still learning how i drive. Depending if I am alone or with family in the car, I drive rather "dad'ish" to unleash the hounds when condistions permit. When I have the first service, I will advise them to see if any issues are out there to fix the delays. The Dealer I bought the car has been pricey for service, but they also have earned that cost with what they do...

I had my updates done at the dealer today. According to the invoice 3 different updates were done, however they did not list the service bulletin/update number. They indicate a TCM update, a PCM update and a BCM update (for an interior light issue) were done.

My initial reaction from the 5 mile drive home.... the throttle delay that I previously experienced during "slow and go" situations is reduced, but not gone. However there is very little, if any, improvement in the tranny downshift speed in the same situation. (I tested only in sport mode, don't know yet if there is any improvement in regular drive mode.

Also, I asked for the tranny fluid to be checked as some reported cars being low... however mine checked normal.

My experience with the latest TCM service bulletin flash update is similar to edfiero's experience. The dead spot is pretty much gone (at least the car reacts to my throttle input at 15-25 mph!) and the trans seems more willing to downshift. But...now that I've driven even more miles on the car since the latest update, I'd say it's adapting back to it's old habits somewhat. It almost seems like unless you drive the car like a bat out of hell, the adaptive transmission wants to go back to short-shifting too quickly into 2nd and 3rd and is more hesitant to make a 2-gear downshift without thinking about it for a a second or two.

Just for kicks, I might disconnect the negative battery terminal to see if the car shifts better right after zeroing out the TCM and ECU again. I wonder how the tuners address the adaptive nature of the transmission shift logic?? I mean, does the car still adapt even after a tune?

I have to admit that I don't drive very aggressively often. Pretty sedate actually for the most part. Maybe that's my problem . . . the shift logic keeps taking me back to grandpa mode because I drive like one more and more now! :driving:

What is the normal time a dealer takes for the updates? I have to have mine in tomorrw to fix "lot dings" that were on the car when I picked it up new. 3 marks on the rear bumper and 1 "hail ding" on the hood. May see if they can do while the exterior is being cleaned up

Have been told that it can take anywhere from 30 minutes to 1 hour.

There are no Service Updates for 2009s that have already been delivered.

Based on your experience, will dealers be willing to reprogram the ECM/TCM if customers are experiencing shifting and throttle flat spot issues, regardless of whether or not there are Service Updates?

Based on your experience, will dealers be willing to reprogram the ECM/TCM if customers are experiencing shifting and throttle flat spot issues, regardless of whether or not there are Service Updates?

Yes. There are diagnostic aids, procedures and revised TCM calibrations in place since mid-August for 2008-2009 G8 GT owners that comment on delayed acceleration or lack of performance from the automatic transmission when applying throttle at low speeds. This may also be described as a flat spotting or delayed shifting at approximately 30-40 km/h (18-25 mph).

Just put it on the RO the way you posted here, and you should be ok.

If there is an issue, take it to the dealership.

i have an '08 so presumably i don't have an issue. i was just wondering aloud because the service bulletin reads as only perform on inventoried '09 vehicles. which i presume means unsold. now, presuming that the dealerships will load bulletin 08254 on said vehicles before delivery makes me sceptical that it'll actually get done. we all know how proactive they (dealership service departments) were with bulletin 08150!! anyway, are customers who have already taken delivery gonna be denied this update simply because their vehicle is no longer considered inventory??

anyway, are customers who have already taken delivery gonna be denied this update simply because their vehicle is no longer considered inventory??

No, they will not be denied. They don't have to be denied. They are not eligible for the Service Update #08254.

Taking car into dealer tomorrow, and figured I'd see if I need to ask for any updates.

There are no Service Updates for 2009s that have already been delivered.

There are diagnostic aids, procedures and revised TCM calibrations in place since mid-August for 2008-2009 G8 GT owners that comment on delayed acceleration or lack of performance from the automatic transmission when applying throttle at low speeds. This may also be described as a flat spotting or delayed shifting at approximately 30-40 km/h (18-25 mph).

so, you and gm are gonna guarantee that all vehicles in inventory that are supposed to get that service bulletin will before they are delivered/sold...

Quit whining and take it to the dealer and ask for all the updates. The computer the service guy looked up my car on didn't show anything but when they hooked it to the computer, there were 9 updates.

General, geez, I have seen like 100 vins so, why not 101 vins :) 6G2EC57Y38L148036

no updates. built 5/23/08.

so, a vehicle that was was supposed to get 08254 while in inventory, but didn't, and is now sold, can't get the update??

listen. The update is part of the programming on vehicles assembled after a certain date. Therefor, no further programming is required.

If you would could you please look mine up?

yes. Its part of the programming (now) from the factory.

General, just a question, the build date is the date they release them to be sent to the dealership.

Why would you think that? The cars were built months before they ever made it to the dealer. Check the sticker on your drivers door jamb for the build date. Mine's 1/08

If you would could you please look mine up?

As it's title says, Service Update #08254 is for Inventory Vehicles only.

No 2008 or 2009 G8 GT that has been delivered is eligible for this update.

So while they may both show open (which doesn't mean that the update haven't been done), they would not be eligible to have it done now.

....the build date is the date they release them to be sent to the dealership.

It does appear that the "Build Date" show in GM VIS is about the date the car is invoiced to the dealership and when it is ready to be shipped. Not the date it was actually built and rolled out of the factory.

I found a "Build date" sticker in my trunk. ;)

okay, maybe i'm confused about "inventory". is "inventory" considered to be cars that have been built but not shipped...therefore the updates will be taken care of before they leave the holding lots?

Can mine be checked: 6G2EC57Y18L127962

Small Dealer, that is what I thought bit wanted to be sure. WHen was the 8254 update realeased and is that again an update that the car should have had done before customer delivery? Here again is whya I ask, I took offical owner ship of it on AUgust 14th. If this update came out before this, I would have expected that they should have done that prior to handing over the keys. The service department at my local dealer is actually very good so I can work with them. Now this again may be moot as per the General, no updates where required.

When was the 8254 update relaeased and is that again an update that the car should have had done before customer delivery?

Service Update #08254 was released into eSI with a date of August 19th. Yes, eligible cars in dealership inventory are requested to be done before delivery.

Any car delivered before that date would not be included in the eligible vehicle population.

For other vehicles, there are diagnostic aids, procedures and revised TCM calibrations in place since mid-August for 2008-2009 G8 GT owners that comment on delayed acceleration or lack of performance from the automatic transmission when applying throttle at low speeds. This may also be described as a flat spotting or delayed shifting at approximately 30-40 km/h (18-25 mph).

requested but not required...therefore many dealerships won't even bother checking their inventory and making the updates before delivery. and once you take delivery your're screwed...amazing!

The only amazing thing is your lack of understanding.

It might help everyone's understanding to have it explained why an update would be released that ONLY applied to cars in inventory (since being in inventory does not effect if a given car has a particular problem).....AND how this update for the inventory cars is different from the other "revised TCM Calibrations" which are available for cars which have been sold.

Thanks

jesus. This stuff shouldnt have ever been brought up. :judge:

sometimes they are released only to inventory because the dealer may have vehicles that were sold before a particular manufacture date that needs the new firmware.

then the updates that are available for sold cars is essentially (in most cases) the same. It's also to update firmware for vehicles that have been sold which 1) the dealer did not update while on lot or 2) was sold before the update even came out (because the vehicle was manufactured, once again, before the updated firmware was released.).

General,

Any updates on mine?

6G2EC57Y28L146990

Thanks!:driving:

So is this TCM issue just the 08's? I just got my 2009 GT this last week and I think the tranny backshifts very sloppy.

General could you please check to see if I need updates 89L154092

supposedly some 09s are also eligible for this update...

General, Sir, If you wouldn't mind checking another one. My Vin is 78L139307.
Thanks in advance.

No need to call me "sir." Although I need the full 17 digit vin or the last 8 of it.

Thanks.

Sorry General, 6G2EC57Y89L154092 Thanks again

Okay, you got it! Here's the whole deal; 6G2EC57Y78L139307.
I think I found a sticker in the trunk that said Feb '08, but would love to know the build date as well. Thanks again!

Now theGeneral has done their job, I will do mine:

So while it may show open (which doesn't mean that the update haven't been done), it would not be eligible to have it done now.

Thanks General! And thank you Small Dealer. So if it wasn't updated, it never will be? Most curious.

So, is it better to tell the dealer to do any TCM updates before you take delivery, or wait until you notice a problem, and get some other update? What's the difference between them? At this point, how many are there?

the Genera can you please check my win for the updates the win is

Thanks

nothing available.

(thanks SmallDealer. Perhaps I need to end this crusade of looking up VINs through VIS as it tends to cause more chaos than help)

i think it depends on the dealership's service department. some are quite responsive and will just load the latest updates if you ask. others want you to complain first before they will do anything. and the whole 08254 service bulletin thing is just strange!

I stopped by my dealer that I purchased my car from to pick up a build sheet and while I was there I asked if there were any updates. They checked and said that there were and they scheduled me for next Monday.

I bought a 2009 g8 gt on 9-3-08 and I am experiencing delayed acceleration. I called my service department and the guy I spoke to said bring it. I have an appointment Friday and I will keep you the board informed.

What kind of gas mileage are people getting with vcm/ecm 93 octane tune?

I'm interested in what the dealer says as I have an '09 that for the first felt like I was going to stall when making a left hand turn onto the freeway. I didn't think the '09's would need an update, but maybe they do.
