Great article!! Most GM US ECUs will advance timing for octane. Will the processor on the G8? If yes I'm running 94, or maybe even miking in 10% 106 octane E85. I wonder how close to maxed out the injectors are?
Actually, none of them will. If they are tuned FOR high octane then yes they will run higher timing. They dont "advance it" on thier own, unless of course you've been running horrible gas and pinged it into the low octane table. The calibration in the G8GT is setup to run on 87 octane and achieved the 361HP on 87 octane BP fuel.
Just some other notes I found interesting about our little journey.
-The fuel door, this thing is hilarious.. you push on it to unlock it and it springs open no more button. It DOES however lock when you lock the doors!
-Ride is remarkably good, even with four people in the car.
-Power is smooth and well delivered although when we romped on it we DID get some wheel hop which is pretty bad in the back seat hehe. It definately seemed better than the GTO!
-Seats, my God someone finally did it.. these seats are actually BETTER than the GTO's! I know, unheard of.. The materials are also incredibly touchy feely hehe
I'll add more as I remember but man its a pretty sweet car
