I've read through the idle tuning guide by RinkRat but I have been unable to track down what I need to change to even out my idle when coming down from RPM.
I have adjusted the throttle follower to decay faster, increased the timing on idle underspeed tables, but everything I'm trying doesn't seem to make a dent. When I come down from RPM to idle it will dip into the 300 RPM range and most of the time recover however I'm tearing up batteries when I have to start it 13 times a day.
I think I've got the idle most of the way dialed in but I'm not 100% sure.
I've also run searches but I couldn't find a solid answer on what I need to look at.
Car is LS1 Trans Am M6, stock cubes, TF Heads and the cam is a 236 int 238 exh 113 lsa, MAF is failed out and will not be used going forward.
Attached is the tune I'm running and the last scan I ran, ignore the first part of the scan as I was playing with RTT but at the end of the tune you can see me goose the throttle a bit and the resulting RPM dip.
