I have an 03 Evo and was in the middle of tuning for E85 with an online tuner. One day my fuel trims wouldn't log anymore, they all read 0. I've tried different laptops and resetting battery and such. The tuner says its not my front o2 either. Has anybody else had their fuel trims stop logging? Any suggestions on where to look would be appreciated. I've been driving an unfinished evo for like 3 months now!
