TPS and stepper motor issue

[Morph1976]

My rocket was running rough and got it down to a faulty TPS sensor and one of the harnesses [every time I moved the harness the tps readings changed)
Looking online I’ve found the tps voltage tolerance should be between .60 - .64v and the stepper motor between .72 - .80v. Now the issue I have is that if it set both the primary and secondary tps to .61v the stepper gives a reading of .53v. If I set the TPs at .67v then the stepper then gives a reading of .72. I can’t seem to get the readings correct. Is there a way of setting the TPs correctly and then manually (or with a programme like tune ecu) setting the stepper motor to the correct voltage or am I missing something. Could it be a faulty sensor . It may be worth mentioning that I have the 3 kn filter setup and have removed the butterfly shims from the secondary

You need the tune ecu software to set the TPS voltage. It tells the ecu to fully retract the stepper motor shaft prior to setting the voltage. Plus handles the adaptation cycle program.

Thanks warp9.9

You will not achieve 0.12 V if you do not install 0.5 mm clearance.
