Idle is set to 1000 RPM when cold, then 850 when warm.
Below 10 - 140 degrees idle is all over the place, RPMs range from 750 to 1050.
Spark varies from 13.5 to 19 degrees at idle.
Once engine warms up its pretty consistent at 850 RPM.
I've got airflow I think ok.
I've reduced over/under speed spark tables.
Anybody got some more ideas?
Thanks,
Dave

if it were me, id want a little more fuel at idle and smooth the VE table. what i done for airflow was found a stock tune in the repository, copied the airflow chart into my tune, and adjusted it from there, up or down, to mimic the factory airflow settings. worth a look.
