which is the best to use on a 92 h22a in a 98 hb?

Maintenance

Either ecu will work for your motor. As long its running a h22 program or dyno tune program. There isnt really any difference between the ecu except the p72 has the iab. It depends if you hooked up your iabs on your h22a. Some ppl have them hooked up and others dont. If you plan on using your iabs then going with the p72 would be a good choice. Also with p28 you can have iabs also function too if you're good with soldering, you can components to make it work. Go on pgfmi.org. Thats a good place to start if you want learn more about ecu and such. I ran both p72 and p28 on my h22 street tuned with my wideband using uberdata. You can look into chrome, hondata, or neptune also.

I prefer the P28. Its what I use with a jdmshit h22 program...

And P72 has a knock board for the knock sensor.

The jdmshit is a pretty good program, the partial throttle tuning could be better.
