Hello there! so I've just got my car running with a refreshed cylinder head and larger cams- (BC280s,Kiggly steel street beehives and AEM cam gears) and I've got my idle stabilized at 1100 rpms or so and my process went like this.. Got the car idling and up to temp, then set ignition timing with the light(made sure to grounds the connector) then worked on getting ISC and LearndIdleAdj to 35 and 135, that all went smoothly and idle is consistent and will return with no issues, what I have questions/concerns on is when I put the car in D or R (since it's auto) the ISC shoots up to compensate for the load on the engine which goes to 90-100 steps, this seems to function correctly but the issue I'm facing is that learned idle will now slowly start climbing back up since ISC is much higher. What this is in turn doing is making the car surge for a second or two when putting it back in park or neutral.. Is there something I can do to where the isc retains functional but when in drive learned idle isnt cranking up making the car surge in park?
