I just installed a b18c5 and i currently cannot run the obd2b itr ecu because my car is obd2a. I do have a p72 ecu from my car. I have read that the mapping is almost the same. So is it ok for me to run this ecu or should i look at buying an obd2a p73?

 

it'll work, but vtec engagement will be too low and your car wont be running it's fullest potential. just get a obd2a to obd1 conversion and run a chipped p28 or something.

 

that's right, vtec engagement is 4500 on gsr? With a chipped obd1 ecu would i still be able to pass smog/emissions?

Thanks for the response.

 

you're also going to hit fuel cut and it's going to feel like you hit a wall....been there done that

I honestly never went to smog with a chipped ecu. But maybe if you put the exact same map for the itr into the p28, you may be able to pass smog.

 

the ecu will also be looking for the butterflies on the intake manifold, but nope they wont be there!
