I have a 2017 mustang GT with lth, pmas intake, gen 3 intake manifold, 47lb injectors and tuned on e85. A few weeks ago i noticed my check engine light come on and my afr was stuck on 9.8 no matter what.
I connected my scanner and saw code P0131 (O2 sensor circuit low voltage bank 1 sensor...
So I am getting a Bama X4/SF4 Tuner for my 2017. One of the options for the custom tune is E85 fuel, would I have to upgrade anything before tuning it or can I just throw in E85? I ask because I know stock it can take a blend of E15
I have a 2017 5.0 and recently installed a PMAS cold air intake (tune required) but have not tuned it just yet. I tried starting it after the installation but it would idle super low and then die out. Could this be just because there is no tune just yet or could there be another reason?
