high idle in park only

[Hondatechcr]

Im trying to fix a issue of sitting in park the idle is very high starts around 1200 and will kind of ramp up to 1600 if I just sit at idle. as soon as I put the car into drive my idle drops to 900+/- 50 rpm. the cam in this car is kind of large not crazy, its a brian tooley stage 4 cam. if I pull some timing out of my idle table could that help the idle to stabilize lower? ive played with frictional airflow intial adding some, would messing with base running airflow/idle airflow help (add/subtract) also is the table in spark/idle adaptive spark control/overspeed be set to pull timing when I overshoot my idle set speed? currently both tables overspeed and underspeed are adding 2 degrees? this is all new to me just trying to chip away at this thingcurrent tune chevelle 71.hpt

Try to zero out the first 3 lines in Throttle Cracker Airflow vs. RPM vs. Speed . Try first from 0 to 1200 rpm (36 speed) then go 1600 rpm if than not work .
