TunerPro RT no spark advance
Just got up and running with TunerPro for datalogging a 1989 383 project I picked up...been sitting a while. New Bosch injectors and cleaning up the grounds got it running. Was throwing a low voltage MAF code; MAF relays are working properly and tested fine in another car (relays new). It overfueling and idling rough/stalling.
TunerPro software shows 160 steps on IAC and never drops below 130/145 (verifying wiring and swapping IAC tonight), but I am not showing ANY spark advance....none at all. Anyone gone some pointers on hunting this down, or is it possible I have not set up my scan software correctly? I imagine if I am not getting any advance that this is the majority of my running issues.
