Hello
Please excuse my ignorance , i am a old school mechanic and truggling with the black magic of ECU,s and management systems . Really need some ideas and advice on the following ....
I have fitted a 1997 BP MX5 engine and manual gearbox to a morris minor and Just trying to finish the wiring and have some problems matching the supplied ECU with the loom . Maybe i have the wrong ECU ?. Everything seems to work but i have no spark at the plugs?
The ECU has part no,s BPU2B at top of label then big letters BPU2
seperate label with E G I BPS9 18 881B .
The loom has a 3 socket plug to connect into this 3 socket ECU , most colours do match with a 1997 wiring diagram i downloaded .
I read somewhere that the 3 plug ECU is for Automatic cars only ??
The 1997 wiring diagram does show 2 Heated oxygen sensors but the pins are blank on this ECU ???
Any help please , much apprerciated.
also correct ECU part numbers .
I am considering junking all the electronics and driving a traditional dizzy off the cam output , anyone done this ?
Cheers all
