Please your help on the setup would greatly be appreciated . I remember someone in here post up a thread like this before but I believe it's lost. I'm running a h22a n/a motor and would like to know which ecu is best to tuned with Hondata? obd 1 p28 or obd 1 p72 . Whats the difference besides redline and vtec?

 

both are about the same except the p72 has knock sensor input.

 

yes and p72 has iabs, which you can add to a p28 if you wanted.If you have an aftermarket intake manifold then u might as well save some money and buy a p28 since you wont need secondaries.

 

yup they are both the same u can modify p28 for p72
