When my FG returns to idle, the spark/ spark source datalog shows the spark going into spark source 9 idle map however the spark dips down to zero and shoots up to around 30 degrees before it settles down. It will also bring up spark source map 2 (borderline spark) momentarily.
See pic of datalog. This causes a momentary unstable idle issue when the car comes to a stop and am wondering if there are hidden maps that could be unlocked to prevent this from happening.
What table determines what spark source is to be used???? Can this table be unlocked???
I notice that the Mustangs have "min spark at idle" which could also help this situation.
The data pic is sitting in Neutral and just jabbing the accelerator for a sec, however it will also do it the same when coasting down to a stop.
