    Hey guys, im new to this forum. Ive got a std delco ecu thats causing issues with the motor, keeps stalling the car randomly, its not a fuel issue, its def the ecu. I have been looken at your older posts about getting a 'map sensor' to tune with the delco. Plsease i need help noone has a legitimate idea of what to do, just kept getting told to get a aftermarket ecu but they are hard to come by. Im located in Perth, Wa
    Cheers guys.

    Doubt it’s a pcm issue. What makes you think it is?

    Well idk what a pcm is hah, but ive had 2 mechanics scan the ecu, both come back with a tone of different codes that make no sense, ive had it cleared before but still stalls the motor... might do it again and check see if something comes back.

    Clearing the codes will do nothing, the codes are appearing to tell you what's wrong. What codes have appeared so far? Not impossible that it's the ECU/PCM, but it's super unlikely.

    Tuning will not fix your problem, and aftermarket ECUs won't really work for this car because the majority can't control the gearbox.

    Thank you for your reply, the codes that appeared where showing RANDOM issues with the car that where clearly not possible. I was thinking of clearing the ecu restarting it and see if it does anything, the motor does nkt stall as much as i did before, but still does it now and then. It is NOT any of the fuel systems ive had a mechanic look at all of it. If you know any advise please let me know thanks.

    Start by posting the error codes as it will help in diagnosis.

    If your getting random error codes for no apparent reason, try unplugging your abs module and see if the codes (besides an abs fault) go away.

    What car you talking about? Is it a vy l67 in a hilux body?
    If so, maybe you have wiring issue?
    I imagine the ecu has vats disabled.

    TBH probably unlikely. While it's not impossible they fail, it's pretty uncommon. It also likely won't work because anti-theft will be a problem when you swap the ECU, either because the BCM from the donor is also in the car, or because your current ECU has VATS has been disabled. If your mechanic is saying the wiring is dodgy you should start there by seeing if it's rubbed through anywhere on the loom or there are places where it's shorting.

    It's using the Commodore auto yeah?

    Are you sure it's a VY ECU? Usually people go down the path of using a VS one when they do an Ecotec conversion, plus if it's a legit VY L67 ECU it'll have a memcal. Post up the details about what's on the sticker on the ECU, won't make a difference but may make it easier to trouble shoot.

    The car hasnt been stalling in a while been driving flat out for 2 days had no stuttering or stalling, the ecu is not bolted to the floor, and my mate said that it could be causing it to stall. Im going to stick it on the floor properky tomorrow and get it recalibrated might fix it idk. What yall think??

    Probably just a loose wire somewhere or crank angle sensor on its way out they die when they get hot and then come back to life after cooling down

    Yeah, looks to be legit. Would sort out your wiring first though, would be good to see what kind of codes you're getting though.
