did you try searching. if you are planning to use hondata and you need a ecu for it then his ecu will be useful, otherwise no.

From what I've heard the p28 is the ecu Hondata re-programs for the H series.

There's really no reason to use that ecu. Like Brendon said, if you're going to use hondata's stand alone engine management, you can use the ecu. Hondata will reprogram it for H series engines and then you can tune with it. But just using the ecu plug-n-play, it's pointless.

what....a GSR ecu will make more power on your h22 than a p13 will its been dyno proven, if your using a standard GSR ecu..u may need to richen up your feul via a vafc...i didnt when i used a stock GSR ecu...btw im using a P28 now that is chipped with a Mugen GSR program, runs better and stronger than any P13 program ive ever run..peace

Can't make a statement like that without posting up a dyno chart.

I dont want to see the damn graph from IR either. That motor had a handfull of stuff that changes the dynamics of the motor. We're talkin a bolt-on Prelude here.

I believe a properly tuned P13 will make just as much power as a P28. Tell me what about the P28 makes it superior? If you have a VAFC and can tune fuel, I don't see it making any more power.

If you had a stock car, the P28 might make more peak HP due to how lean it runs up top.

No way in hell would you want to do this without a vafc or hondata becasue of the fuel factor. The H22 would lean out at higher RPM's. As far as it has been proven, show it!!!!!! I call BS on that statement. Like 4bidden said we are talking bolt-ons.

simmer down there it makes more power for 2 reasons..also im talking about a GSR ecu not a civic single cam one...it has different maps which make power higher, so when a p13 drops off the p72 program is still feeding feul, and yes an H22 will continue to make power past 7k...its comletely up top that the GSR makes more power, its only like 11hp, but still making power higher, allows you to shift higher, thus falling higher in the revs each time...thats my only point...but hey its all good people can run whatever they want....peace bro

Where are you getting 11hp from?

How is the magic P72 making more power?

^^^ asking the question. That makes no sense what so ever. Show me a dyno. Better yet I will go borrow my friends GSR and see. But then we are still at the same spot no proof.

Do what you want. Just make sure you get something that will control the secondaries so you don't have to keep them open all the time. You DO lose low end hp and tq with the secondaries always open. I tested it myself on a dyno so don't call me a liar, lol. I'll see if I can get the graphs to show you guys.

I believe you about the secondaries. Tried it myself and felt a difference.
