How is WOT determined or is a programable variable?

 

Good question.
I believe the PCM uses the Power enrichment settings to dictate WOT for the engine parameters and the WOT shift parameters, but the shift tables use TPS%....

 

Any reference to WOT refers to all TP values above the TP that has been set as the the minimum that is considered WOT.

Throttle response(i.e. throttle blade vs pedal position) is also somewhat programmable. And there is a table(not shown here) for max allowed TP vs RPM.

 

I was just wondering. My tuner has my converter set to not lock at all in WOT, but in third at 4200 RPM it feels and sounds like it's locking. I was curious if WOT was set higher that the TPS was reading, allowing it to lock the verter. I'ts going in for some fine tuning April 8th and I was going to mention this to him. Thanks for all the help.

 

got the truck back. What a difference. No more 3rd gear converter lock, no more low RPM surge, traffic sucks. It feels faster all over the RPM range.
