bradtrann Posted March 29 Report Share Posted March 29 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!

Adamw Posted March 30 Report Share Posted March 30 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. Quote Link to comment Share on other sites More sharing options...
bradtrann Posted March 30 Author Report Share Posted March 30 Thanks Adam, I tried what you suggested and it seems a little bit better coming from a stop. Although, downshift rev matching feels more sluggish and getting on throttle under 2k rpm is still sputtery.
