Hello All,
I'm very new to the forum and tuning in general, but I'll try to be a specific as I can with my issue. The car starts/idles and makes great power throughout the power band. The only issue I see is when I'm coming to a stop, at times I leave the car in gear while decelerating before pushing the clutch in and begin to brake for the stop. It is when I push the clutch in after "engine braking" that intermittently the engine will drop RPM faster than normal and at times will die all together. The issue is with the IAC values dropping when decelerating in-gear, so when the clutch-in action is performed, the engine is starved of air and dies. I've attached my latest tune file and a log showing the issue. See minute 4:10 and 9:55 and compare the IAC values to other points in the log where I'm coming to a stop (see minute 7:30). I believe the correction lies in the throttle cracker/follower tables, but not sure where to go from here.
