Hi all,
I have a series 1 r33 manual with all standard mods. I sourced a new ecu which has been remapped. when the new ecu is plugged in problems arise...
Start car. This seems fine, idle high on cold map as expected. Note i have not tried revving the motor.
Now, here is the really weird bit. When moving the gear stick from side to side revs drop like a small miss and i hear the fuel pump cut out and turn back on. Now clutch in and select a gear and bang she stalls (clutch still in). engine check light is now on. Car needs to be turned off completely to clear engine check light.
Now with motor not running and ignition on (car turned off fully to clear engine check light) i move the gear stick as described above and can hear the fuel pump start priming again. So i switch on keys till red lights on dash (fuel pump primes) then after the fuel pump stops priming i move the gear stick to either the left or right and the fuel pump primes again. Something seems top be triggering this.
I unplugged the new ecu from the loom put my old ecu back in and she works.. Replugged the new tuned ecu into the car ensuring loom was connected tightly and this same thing resulted.
Is there some kind of switch around the gear box which sends signals back to the ecu?
OK ECU serial numbers etc
New tuned rom ecu (problem ECU)
23710-21U01
MEC-R521 A1 4321
Old standard ecu (Working Fine ECU)
23710-21U01
MEC-R521 A1 3X22
Any help would be much appreciated.
