E36 M5x Turbo low rpm sputter


Recommended Posts

Hey guys,
After switching to e85, my car has been sputtering at low rpms when I blip throttle when idling, going off from a stop and just driving normally and touch throttle. I see that it leans out for a second or two then it proceeds to be going normal. Been trying to figure out what I need to change, Thanks!

I would say you have way too much accel fuel, your idle inj PW is 0.46mS and you are dumping in 1.6mS of accel fuel with only a relatively gentle throttle movement - 350% extra fuel seems a bit excessive.

I would suggest enabling async injection as it reduces the need fr accel fuel a lot, and try the changes in green.
