TPS problem - 4.7v @ idle, 2.0v @ WOT.... Reverse to normal??!

I have logged my Throttle Position Sensor and I am getting 4.7v at idle (throttle closed) and 2.0v at wide open throttle. the voltage output from the TPS is dropping as I apply more throttle.

It should be opposite to this (reverse).

What could be causing this?!?!?!

Any help is greatly appreciated!

ps: Car is a 1991 Nissan Skyline R32, running a R34 (Year 2000) rb25de. The engine is being run using a R32 loom and R32 ecu.
