Using a GM ECM...what should the TPS (Ford) on an Accufab throttle body be adjusted to? The GM setting or the Ford setting? If its the Ford setting, what are they? I don't have my Ford 5.0 manual available right now. Thanks a lot!

 

The ECM/PCM is Delco. It's going to be expecting the same kind of inputs as any other Delco ECM. Set it at 0.54V at the closed throttle position.

 

Thanks Vader, I figured you'd be the one to answer!

 

Ok, I slotted the Ford TPS to get more adjustment and have the low side setting at .54 volts. The problem now is that the WOT reading is only about 4.05 volts, not the 4.5 volts it was before. I'm thinking there is no way to get the proper adjustment out of the Ford TPS, since its range is approximately 3.5 volts and the GM is 4 volts. I may look into using the GM TPS after all...not sure what to do.
