ok so i read the post....https://honda-tech.com/zerothread?id=567799..... And i Had the question about the P72.... Firedrake said that the P74/75 are the best pick for the H23 but what is i don't want to lose the IAB's. or dose it matter if i plan to boost the motor.. So what i'm asking is...will the p72 still work with the H23, ahter i install Hondata or uberdata....? which would be best......

 

Yes the p72 will work. You will only be using the lower maps because you don't have vtec. Personally the LS ecu will work just fine but if you really want butterfly action the the p72 is really the only way to go.
