Throttle is calculated thus:
Throttle = (TPS raw - TPS min) / (TPS max - TPS min)
Most ECUs also allow you to invert the raw throttle voltage, for throttles that give a high voltage for closed.
TPS to Load, is only used to default a failed primary load sensor, such as MAF or MAP, and is a "limp home" feature.

ok great, thank you.
so what your saying when i have scaled my TPS raw it does not matter if any of my other TPS fuctions DONT go up on the scale? As they only go up about 25% up the scale!???? ( This is whats worrying me.)

No your TPS signal does not have to match the tps to load table.
Scale your tps raw and you will be fine.
Hope this helps
