Fuel issue

[devildog0905]

I am MHD stage 2 on 93 octane. FMIC, chargepipe, downpipes, exhaust, stage 2 LPFP. After installing the LPFP, I started to get a rough idle and misfires. It was recommended to try a new EKPM3 (my car had a EKPM2). I just switched it out and everything seems good. I haven't been able to log because of the misfires. I just took it out and made a log. How's it look?

Looks good. lpfp and rail pressure are strong (to get to your point). Try and reset your fuel adaptations to fix the STFT on bank 1.

Side note: I'm surprised you didn't have to code the new ekpm.

semper fi devil dog. Drive safe.

Thanks. How do you reset your fuel adaptations?

Also. I thought I might have to code the new EKPM3. I read multiple posts where people didn't code them and everything was fine. Also read a few where people coded them and didn't see a difference. I took mine out of a e92, so maybe that made the difference

Ah, so the previous car already had it coded.
