Was the ECU Delphi? And all electronics have delphi branding on it
Or if you want post a picture of the ECU , stator of the wrecked engine and its flywheel.
It could likely be the stator unit compatibility with ECU due to fact certain stators want certain ECUs.
The stator and ECU are the 2 to talk to each other while cranking to make pulse timings
Then ECU primes the fuel pump and wakes up all other electrics to make flames (sparks) to get her going
The carby vs efi engine = purely the actually sensors on the motor to switch. (ET sensor , if its there on the head. Some dont have it. Stator unit, NEUTRAL sensor (efi tends to have 6 dots on it. Carby gearbox sensors tend to have 1 dot or 5)
