Im almost sure that something is wrong with BMS PI Controller.
Unplugged the PI fuse, car running smooth, logs normal. Plugging in PI fuse; rough idling, limp acceleration, and logs showing AFR dropping near “1”.

Nice to say that the rough idling happens right after the “Meth” signal shows in (which is plugged in PI in order to see the signal of it).

Await for some straighten. Thanks!
I already tried setting fuel bias to 0, but the rough idling doesnt stop.
The only way to make it stop is mechanically disabling it by unplugging the fuse.
Maybe some problem with the controller? Somebody see this before?
