Ecu –- HELP



  • REPLACED THE ENGINE IN MY L REG WITH ONE FROM A P REG, NUMPTY OF A MECHANIC FORGOT TO GET THE ECU THAT GOES WITH IT, CAN I SOURCE A REPLACEMENT USING THE ENGINE NUMBER, DONOR VEHICLE WAS CRUSHED AFTER ENGINE REMOVED,,,,, REALLY MISSING MY BEASTIE AND NEED HER BACK ON THE ROAD

    MANY THANKS



  • Please turn off your caps lock as it looks like your shouting…

    Was it a like for like engine..



  • So whats the problem exactly?

    if both engines are same cc and obd1 you can use existing ecu??



  • Sorry 'bout caps lock, was finidhed typing before i looked up…...was in a hurry as working at the time :-)

    only difference in engine is replacement has a/c which i believe has it's own ecu ????

    P.S i'm a chef no a mechanic,,, so free steak to whoever gets me oot o the shite ;-)



  • cc is same,, obd1???

    thanks for taking the time to reply so far guys



  • yeh i would have thought just a k801 ecu that matches the year of your new engine would do.



  • Shouldn't matter if it's odb 1 or 2. The engine isn't restricted by odb it's the wiring harness that is. The engine will connect up to either an odb1 or 2 harness as the sensors on it aren't limited to either.

    Only time odb is considered is when you're sticking in a ZE or DE (2.5 V6) as the ecu's to run those need an odb 1 wiring harness to connect to.

    You can run a ZE (from odb 1 car) on a K836 (1.8 V6 odb 2) ECU It'll run just not to it's full potential.

    As long it's a 1.8 V6 you chucked in there the original ECU should run it fine.

    Shouldn't matter if the donor car had air con either. I'm guessing yours doesn't, so unless you've swapped over all the air con equipment too you should be fine.
    Only thing that would be related to air con on the donor engine would be the compressor and that should've been removed when dropped into your car, as it's not needed.

    What problems are you having? It should've been a case of drop engine in, connect it up and fire it up using your original ECU.

    You might have to swap your distributor over from the dead engine, wiring is slightly different from odb1 to odb2 but that should be it to get it to run.
