Hey guys, I have an idea, wondering if I can get some input and feedback.

Right now I'm running an Un-Tuned all motor 1997 Acura Integra.

The car has a B16A 81mm bored and honed block with a b18c1 head.

The engine has Type R cams and Type R pistons.
Right now the car is running a p72 A02 ECU (Integra GSR obd2).

I was wondering, since the car is running closer to OEM Type R than It is OEM GSR, if it would be a smart decision to put in a Type R ECU (P73 obd2).

The compression ratios and everything practically match, so..

Only reason I ask is because it's my daily, wondering if the Type R ECU would be better for the car running un-tuned than the current GSR ECU.

Input / feedback?

Thanks!

 

That or that is not right for this type of engine
you should get a tunable ecu and get a right tune,
there is a lot to gain with a good tune on this kind of setups.

 

if you didn't have the option of a chiped ecu, the P73 would be more ideal, but the P72 will still run it decently as long as the knock sensor is hooked up.
but obviously a tuned ECU will run it much better than either stock ECU.
