Hi guys, I’m working on a 1990 tbi 350 truck with a 7747 $42 ecm, Tunerpro RT v5 and a moates autoprom. The problem I’m having is randomly when I try to start the truck, all the data shown in TP datalogger is at maximum values and the truck floods and won’t run. I’ve tried to mess with cable connection, connection procedure and everything in between. Is there something in the ecm could be giving bad data or could it be the autoprom? Sometimes the truck fires up and runs great and has proper data,but occasionally this issue comes up. Thanks for any help.
