Lou, yes I believe that is true. It seems as if that programmer is no longer being produced, but I don't see any reason why you need that specific programmer any one that can handle the same processor should work fine, if you feel inclined to upgrade.

Did you use the relay board? I've worked with those small connecters before, and the db37 on the megasquirt... won't it be a tight squeeze because you are going to need several 18gauge runs and a few 14 for the injectors and ground.... how did you take care of that?

And also, since the GM throttle body has an iac not just a flap, I can't directly interface that to the MS... do you think it'd be an issue if I just left the idle solenoid output of the MS unhooked?
