    I bought a car that had a b16a in it. It was being run using the p73 ecu. Everything I have read says to use either a p30 or chipped p28. What are the reasons for using the p73, is it just bad judgement or can it have some benefit.

    It's meant to be used on an ITR engine, which is a 1.8 liter as opposed to your 1.6 liter. It will run the motor well enough, but the fuel maps won't be exactly right. You could be running a bit rich...

    Well that makes sense...the air/fuel gauge said it was rich when I cranked it up. Since I am building the engine my best bet is the chipped p28 right? That will give me the ability to tune to fit my specific build type correct?

    Absolutely. A chipped P28 would probably be the best option for you. :thumbsup:
