Power FC HELP!!!

[33SOM]

OK heres the problem.

Ive got a custom plenum with a throttle body that only accepts XF throttle position sensors.

Problem is that anything under half throttle the engine light is oln and the car misses badly until im over half throttle. My mechanic said it was TPS related.

Does anyone know what the TPS voltages on a factory equiped TPS 33 are at idle and full throttle??

What other sensors out there could I use?

Does this sound like the problem??

Thanks

the standard r33 tps is a 0-4V signal. Should read 0 or there abouts at closed throttle and near enough to 4 at WOT

Hi

I think its 5 volts at 100% open. I've got a 96 r33 with a SAFC2 and It reports 0volts at 0% and 5volts at 100% open.

The r33 service manual also used to talk about 4.8v or 5v i forget now...

Hmm mines sez 1.5 volts at full throttle.

Anyone know what other TPSs go onto a XF fitting??
