Very cool tool Steevo! Thank you. I'm working with a 94 Fleetwood PCM. Connectivity seems very stable. I am having issues with my TPS fluctuating back and forth from 0 to 31%. Not sure what to make of it, it tests fine. I need a new IAC and connections to the VSS.
that's not normal. does it 'test fine' on a scope, or just a volt meter? you should start the logger (car not running) then slowly push the gas pedal to the floor, and then slowly back off again a few times. then graph tps and see what it looks like.
