E85 considerations

[DougS550]

i just started using a livernois flex fuel tune on mine-they told me to do a "drive cycle" any time while filling with any E85 or switching from 93 to E85 or E85 to 93. drive cycle being driving the vehicle a good 10 mins at under 50 percent throttle to allow the computer to read the fuel and adjust accordingly for it. this way you dont need to test the percent of ethanol for every fill up.

i have noticed a change in start ups with the e85- it is a little less "potent" of a start up, for lack of a better term. used to have a traditional loud, blaring, intense cold start we all think of. now with E85, there's a little bit of a lag when it first fires up and starts, then it goes to the normal intense idle. this is between 70 and maybe lower 90 degree ambient temps. not sure what itll be like when it's significantly colder here in chicago winters. ill probably go back to 93.

i definitely noticed a power bump. my car is otherwise essentially stock, save for a roush axle back and drop in air filter. neither of which likely added much power, if any.

Thank you for the help. That really helps me so I know what to expect. Good luck with your set up.

Will do. I went with FIC1000s and the new JN2uning budget 2.0 system with upgraded billet rails for fueling. I plan to stick with Shaun @ AED for my tuning

That set up will be nice. Thank you for passing your build info with the forum. Keep us posted and have fun.

My car was awesome on E85 tune only. Now Procharged on E85. I wouldn't let the dealer work on my car anyway, so warranty isn't an issue. Pure beast now. Get ready to add drag radials with that E85 tune.

Shaun @ AED had a similar process for any time making fuel changes like e to pump etc on his flex. No wot for first few minutes, varying rpm between 2500-3500, then AFRs compensated. Or just do a kam reset if in a hurry.

That makes sense. Thanks.
