E85

[Francos24]

So i tuned my car to e85 and after about a day on it I decided to gun it and i got a check engine light p0171 and i felt like i lost some of my power
Also is it okay to run e85 on a e70 tune

E70 should be the minimum, anything above is good. go back to bama.

Did you data log it? My first E85 tune came in lean under WoT.

Ditch the Bama tune...there is loads of negatives on this forum with Bama.

I would go with a better tuner for sure.

This code is influenced by the downstream sensor, are you running stock cats?

I'd be surprised if you were actually running lean, its very difficult to make this car truly run lean unless you do some egregious stuff.

Nope, you need E85 because the computer is going to read the ethanol contact and if it's off, the sensor will not like it. Do you have an E85 tune or E70? Just wanna be sure.
