I just started out modding this car, but one of the first things I wanted was to run a straight E85 tune. Now I know that the flex fuel thing is OK from the factory, but factory E85 tuning is hardly optimized for running on this fine "race-gas for the street" fuel. Needed more timing!!! Torrie said he added a bunch of timing in the base maps, but after some logging and test drives the car is seeming to like +4 degrees global added on top of that!!! After trims settle down I'll send him some logs to make needed adjustments. There could be more lurking!!!
MPG's: For comparison, MPG dropped to about 24-25 for the first full tank of E85 on the stock tune. The first tank with Unleashed tune was 28, and this morning with +4 degrees global I pulled an indicated 35 MPG (been within 1 MPG calculated vs indicated on the dash so far). 90% highway driving for me, running about 4-5 MPH over speed limits with cruise set on fairly flat ground, full throttle entrance ramps though! [driving]
Before I get a dyno run to see what she's putting down, I'm going to at least wait until I get a header and MS3 catback put on. Until then, I know I'm putting down more power simply by first gear runs on the same "test track" near my house. 1st gear has no issues with stock tune, with E85 tune (even without any added tweaks yet) 1st gear flashes the traction control at me and the bog between 1st and 2nd shift is gone. This is roll-on to flat foot i.e. clutch fully out, then flooring it. #progress [twothumbs]
