I noticed at the weekend that my FD pulls alot better on part throttle than it does on WOT. I did a little research and this is would appear to have something to do with the Throttle Position Sensor.
I checked the voltages read by the PFC and they are both out of the ranges. Does anyone know which voltages relate to the values on the PFC.
VTA1 -
VTA2 -
The voltages I looked up are
closed / open
0.7-1.2v / 4.8-5.0v
0.1-0.7v / 4.2-4.6v
I just don\'t know what ones are what since these values are usually adjusted with a Multimeter.
Have a look here:

Gives a good picture of how to test and check tps adjustment :)

VTA 1 is the full range sensor
VTA 2 is the narrow range sensor
full/narrow explanation is in the link above.
Cheers for that.
Just for future reference.
Fully Closed Closed to Open Fully Open
Full R(VTA1) 0.1 - 0.7 V 0.4 - 4.3 V 4.2 - 4.6V
Nar R(VTA2) 0.75 - 1.25 V 1.0 - 5.0 V 4.8 - 5.0 V
