Somehow today I stumbled on thinking about this unit again. What I been focusing on is the adaptive timing for the idle, like you mention when going from Park (or neutral) into drive and it keeps idle. I also believe this works when the AC turns on. From your signature you have AC - does the HEI deal with that too? Any idea if that is bad for the engine to be bumping the timing all around to keep stable idle during the cases (in drive, in park, AC on/off)? Heck, how does it know you are in idle or not?

Also, do you have tach in your cluster too? I believe it has a wire for that but currently the dash (I upgraded to a stock one in my cluster) and it connects to the coil.

Sorry for the 1 zillion questions, hope you don't mind them!
I see by your last thread you ordered one. Mine is working great I have a repo factory tach and it works great. I also use the lock feature when leaving my truck in a parking lot along with a Club.
