    If I don't soft code out secondary air injection and rear lambdas and egr would it produce running issues or will it just store codes?

    Finished off the wiring have a supply at both the Injectors and coils but I've no spark or no injectors opening I know ecu still is immobilised but I would have thought it would have at least started then cut out

    aye it should start but cut out like you said

    sounds like it's not getting power to the ecu somewhere

    Another fault found pin3 red/green live supply to ecu terminal has backed out of its holder in the plug it's just missing contact with ecu so hopefully have it connected tomorrow

    I haven't tried connecting as yet mate I wanted to get it sparking and fuel as you said it should still start then cut out so now I'm at that stage at least we now have a live ecu it runs and cuts out as it should

    I think ecu going away for immobiliser defeat and soft coding of the rest of things not needed as it's near show time and running out of time to get things done

    yes like I said earlier in the thread the BDE wiring diagram has an error and doesnt show the ignition live to pin 21, the R32 BFH wiring diagram does show this feed though and the ECU wiring is 99% the same
