Looking for LS1 e85 Tune...

[EndlessMotoSports]

Does anyone have a e85 LS1 tune they can post? I'd like to look at some of the differences....

My specific car is;

2004 GTO
SBE
PRC 5.3 Stage 2.5 Heads
Texas Speed Cam 233/239
LT/Exhaust/Intake
Fuel Pump Upgrade
Fuel Injector Development 70lb/hr injectors

I'm going to do a straight 93 tune and then a straight e85 since I dont want to deal with the hassle of a flex fuel conversion.

Thanks!

the only difference should be changing the stoich value. if your pump tune is bang on by changing that one value it should be on the money on E85.

and E85 will generally have more timing advance at WOT. standard static comp ratio engines really don't make much more power on E85. they will take more timing but it generally doesn't make a great deal more horsepower.

boosted or high comp engines on the other hand benefit well from E85.
if youre doing 2 separate fuel tunes and not flex fuel I would expect the only differences to be the stoich value and some timings at WOT
