EDITED AND UPDATED, SEE BELOW.
Ok heres the deal, I have installed a 4.3V Zenier diode on the PIM line, i have CUT (Totally severed and capped) the PIM pressure sensor wire DIRECTLY at the ECU based on http://www.alltrac.net/reference/ST185ECU.JPG. I have also disconnected the turbo pressure sensor harness at the pressure sensor.
The results were as follows, on addition of the Zenier diode, nothing happened (Yes, it is teh right PIM line, same colour as the wire going to the pressure sensor), and fuel cut stayed (yes it was the right diode). F
Following this i cut the PIM line with scissors and taped both ends of the tape. The boost pressure gauge on the dash still worked.... and the fuel cut stayed. (at ~12psi)
Following this, i disconnected the wiring harness AT the pressure sensor. This made the stock boost gauge on my dash read max boost when i start the car (it just max's out and stays there)... But i still get damn fuel cut!
ARGH this is painfull. What is going on??! I get codes 34, and 35 every time it fuel cuts - code 35 probably because i have cut the wire hence it detects a short.
HOW THE HELL can it tell what boost to fuel cut at if i dont even have the damn sensor plugged in???????????????????????????????? Something else simply MUST be triggering the fuel cut... but what?
I Don't want any fuel cut at all, ever, not once. Is there any way i can find whatever it is that cuts the fuel (Relay? Solenoid?) And smash the crap out of it with a spade?
This is incredibly infuriating
Any ideas greatly appreciated,
