    i have a ej9 with the b18c4 engine and im using the d16y8 loom ..

    i want to use a standard ECU , i know i can't use the c4 ECU because of the imobiliser so what i need to know is what ECU i can use so it runs properly ,

    i know the loom is obd2a but i also have the jumper harness to obd1 if it is nessesary

    any help would be good help thank you :Smile:

    are you seriously kidding? you just want to plug an ECU in after doing an engine swap from d16-b18 and it to run fine straight away?

    why do you think you can use a standard ECU? you need to get a socketed p28 or p30 and then pay someone to tune the car for you

    You could just knock the immobiliser out the c4 ECU, convert the harness and run that, but the way carlsberg says will get you better performance.

    yeh a just got a p30 chipped and got a basemap knocked up to run on for my c4, done the job, probably less hastle than messing with the standard ECU, now running hondata s300 now, but chipped p30 or p28 is defo the way to do it if you ask me

    i'v seen people runnin standard p30's on the c4 it run's a little lean but nothin major don't take my word for it tho.. Get a p28 or p30 and chip it

    if you want a plug and play then delete immobiliser, obd2a to 1 harness and add the wires you need...only if your not looking to tune later on in life....

    how do you delete the immobilser mate just out interest does a p73 work on the c4 ?

    i have just found out the ECU im using is a p72 with a jun chip and its rubbish ,,

    its a bitch to start cold ,it won't idle until its warmed up and the VTEC don't seem to kick in until about 6000 RPM

    unless you can get hold of a p75, i would go carlsbergs route. p30/28 and have it tuned
