After going back up to xspec today to see the car (much more easy to understand whats going on from seeing/hearing it rather than just talking by phone) a few things are clear:
- There is 100% nothing signal/power wise reaching the stepper motor from the ECU
- Car runs perfectly when manually imitating the stepper motor and a steady idle/tickover is achieved, bloody smooth too, love it.
- Its the adapter loom which looks to be at fault as where the metal bits are that the ECU plugs into there is one which is pushed back (too far to pull back out, and not making contact with the ECU pin) if this is the contact point for the stepper motor signal/power to go from then this is the cause.
- Also theyre pretty confident that the basemap given on the ECU when it was bought has been given for a TB setup rather than standard TB bit the stepper motor in use
I should know later this afternoon exactly whats wrong, adapter loom being the primary suspect so far.
Ive also dropped off the standard ECU which is currently locked to the old cars immobiliser code. Hopefully this will be easy to unlock and can be tried on my car just to see if it will run fine then (obviously KMS adaptor loom is out of the equasion and all original contact points will be in place)
See how things go. Ill update later
