Re: another ecu question. (lude97dude)
1) It will run really lean http://www.importreview.com/reviews/PreludeECUtest.html
2) Your ATTS won't work.
3) Throw a code 54 becuase the ecu will be looking for the CKF Crank Fluctuation sensor that the H22a doesn't have (doesn't affect performance though)
4) VTEC will engage too early, and your secondary runners open too late
I am running an OBD2 gs-r ecu on my car right now, but we reprogrammed the igniton/fuel/vtec so it works properly. Unless you have at a minimum a v-afc and don't care about your atts system don't do it.

hey satan_srv, what's your setup? did you run hondata and v-afc or just hondata and how would someone like myself get that kinda setup? in the link it says the h22a ecu is better for daily driver but if granny was to drive the gsr ecu (always going below 4400rpm) then it would be better wouldn't it?

very interesting. thanks for the link. you are INSANE!

I think the Import Review Article is misleading becuase they just ran them stock vs. stock. I would rather see V-AFC's used on both ecus to level the playing field. so that given a set VTEC engagement and a standard A/F ratio which ecu performs better. So basically you're testing which one has better ignition timing for top end power. If done right I don't see how daily driving would suffer at all.
My 97 GS-R ecu was custom programmed using TechTom tools from Japan. There is a dude in Toronto that was trained at TRD in Japan and knows some crazy ish...
So unless you're in Toronto, you'll have a tough time finding anyone that can tune an OBD2 ecu. I could sell my ecu though for the right price. I made +20whp with it and +15tq. I just would want to sell it cause I am destroking and my motor will be totally different now, so I'm thinking Hondata Stage 2 and I found a guy with a Hondata program on an F20B motor already so I may borrow him maps.
