[Gmecm] TPS for diesel and now PCM Algorithm

[Don Sauman]

Chris

I was under the impression that it was a potentiometer as in a gas 
vehicle, and might have been used to control the shift points for say a 
4L80E. If that is not the case then the PCM for the 4L80E would have to 
be running a fairly simple algorithm when working with a 6.2 diesel and 
mechanical injector pump..

Has anyone worked this out or would like to suggest some clues?

Thanks
Don
