Car: 92 Honda Prelude
Motor: h22a
Transmission: Manual
ECU: p28 with hondata s100

Should I be using the p72? If so, where would be best to look? I searched threads already.

Thanks for the help!

It is up to you. If you want the secondary runners and knock sensor operational then you need the P72.

hey this page here http://hondata.com/engines.html is confusing on this subject. The section for H22 does not have the knock sensor checked off. Makes me think there are noe sutible ECMs for the H22. What is the story?
