VTPS Calibrate, inverted readings
OK maybe i have just been sniffing too much solder tonight, but i cant get my VTPS to calibrate with my MSPNP 2
Car is 91, 1.6 with ARTech turbo set up and T25 snail.
I installed the VTPS tonight, followed its instructions to have Red wire to top pin and the green/white to lower pin.
However when i start the calibration my "Full Throttle" reading is lower than "closed throttle"
No problem i thought, just reverse pins 1 and 3 to sort this out but no same again.
The numbers change red to top pin gives closed throttle 450ish and drops to 200ish on full throttle position.
If i reverse the pins i get closed throttle 650ish and full 300ish
tuning manual says full throttle number must be higher than closed? it just wont happen for me tonight,
anyone else encountered this? all my searches have just pointed to reversing the wiring.
on a plus side i got the immobiliser wiring tidied up and ran a power supply into the cubby box.

Thank Brains, i should know to quit when it gets to 2am and you start tinkering that just one more job.
Fitted new connectors as old ones were super crusty. Then did this. So blindingly obvious not sure how i missed it last night.
Fitted up and calibrated in five minutes only for it to have a misfire upon starting.
Ah the joys of modded motor builds. Had to leave to work so will look into the misfire on monday. -_-
