Ok I have ruined 2 7427 ecm's trying to emulate and datalog at idle. I have another car with a 90 quad4 707 ecm that has lost all power after wot tuning and can't figure out why.
My question is can I damage an ecm with the autoprom1 and tunerpro? I fat finger the switches some times, moving both or wrong one for what I'm doing. Am I spiking ecm's with baud switch or something?
