The E85 sensor can only be setup with Efilive for now, the PCM has to be calibrated for it, plus there is something needed to be done with the sensor as well once is plugged, we had a thread about it in the tuning section. It's not as easy as it sounds otherwise you'll have more 2 people asking for it
, Explicitsaint was one of them, in any case, tuning for E85 is fairly easy,
Change your stoich point in the calibration for E85,
change your crank fuel if you live in a region where it gets cold out
increase timing in general,
and of course, your MAF/VE calibration has to be spot on for this to work, see, a PE rape tune won't work just changing the stoich to work with E85 because the fueling would be all over the place, And yes, with your mods, you can run E85, i ran it with Kooks mids, and Scooby is testing with a CAM, (don't know if he has LT's yet), but Scooby is also at elevation so in his application, he should have injectors for it with a cam. in my application, i used to see 77-80% IDC (injector duty cycle, which is good but almost maxed, and because i like to run my crap fairly rich)
I would be trying E85 soon with my LT's, i just need to find out if our local 1/8 mile track is still open for the year
i've been trying to get into the 7's with the ****ty 91 octane we have, so E85 should make my car .2 faster based on previous results.
