Car/Engine is running well on the corn juice... (E85/70%). Pulls very strong and sounds excellent. Wish I had a local shop to dyno her... feels like a 25% increase over stock by the butt dyno.

wow. your logs look great. I wish I could get my engine loads that high. Any mods?

[jamesm]

i wish i could run 33 degrees of timing at redline lol. logs look great. better than any e-tune log i've read. impressive !

[krulux]

The only mods so far are a drop-in K&N filter in the stock air box, local muffler shop installed 2.5" Magnaflow catback... and Vishnu's awesome stg2E85 tune. And my heavy foot

I will likely purchase the OpenFlash Header when available (and if Santa is nice... later on plan to either SC or Turbo.)

After the header purchase I'll need more rubber on the road, so that will be the next major purchase. (Looking at the Mach-V Awesome 17x9's with some Hankook RS3's or similar)

Oh yeah, it was a chilly 37deg this morning at cold start - she fired up no trouble, first bump of the key....

I've been on the stg2 e85 tune over the weekend and so far it pulls like a beast.

LTFT were kinda funky (high variances) at first but this morning everything seems to look much more stable

logs look good. Looks like you must be getting similar ethanol to what I'm getting in SD...our trims are nearly identical.

Yea. I've been comparing mine with yours since I'm in OC, to make sure it looks normal and was quite happy when I ended up with similar numbers!

For people who are running aftermarket headers and E85 Stage 2, what are we to gather from this thread/result? That the headers aren't really worth it and we would be fine sticking with stock, or that there are more gains to be made with aftermarket headers and that this tune is on the conservative side?

Good stuff logs looks good on e85. ~33 degrees of timing and car is happy.

There are significant improvement when running header on this car especially in the min range/torque dip area. We are testing/dynoing our OpenFlash Header so more info will be released soon.....

Looking forward to seeing the numbers on the OFHeader...

Would be nice to see a future OpenFlash overpipe/downpipe/frontpipe as well?

can confirm another stock car running fine on E85. the acceleration difference did surprise me at first. butt dyno very happy.

pumped 11.7 gallons of e85 which nets e76. ran the car first on the stage 1 tune and the advanced multiplier was at 0.7. drove around the block and when the stft went beyond -10 up to -25 i pulled over and flashed the stage 2 e85. afterwards the fuel trims read mostly on the negative -5-10 range but the advanced multiplier stayed at 1.0. im sure the ecu will need more miles to adjust the fuel trims.

i would like to note that at idle the stft are around -14, will compare with another car tonight to see if they have the same.

Update: the idle fuel trims have settled below +/-5%

Sounds good. SFTF (or even LTFT) at idle aren't isn't very important. What really matters is what LTPF trims do under load (when STFT go to 0, ie, open loop).

gave e85 a shot today. anyone try it on a winter blend yet? ran the car down and put about 11.4 gallons in. drove about 2.5 miles home and then flashed the map. i put about 30 miles on it driving easy and then did one second gear pull. everytime i try to download the data log openflash manager freezes. maybe ill try to reinstall it. fuel trims were negative -10ish and seemed to be a rich afr.

@Lytheum

Shiv uncovered the issue late last night.
