Hi guys,
So I'm making progress with the FAST tuning. But as usual, I have a question.
When I'm driving along and come up to a stop, I'll generally engine brake the car by leaving it in gear, then press in the clutch right before stopping. Well, for some reason when I do this, the engine wants to stall. It will stumble and idle around 600-700rpm until I blip the throttle, and then it will recover and idle fine.
Any idea what might cause this? Or what setting in the FAST ECU I need to change to fix this? Nothing is jumping out at me from my data logs. The only thing I can think of is the IAC is closing down while decelerating, and maybe that's causing the problem. But using the throttle follower table, there isn't anything I can do.
Any thoughts would be appreciated!
Thanx!
Bryan
