I am seeing that people here claim 230 WHP or more with simple bolt ons but I tihnk it is harder to get than simple bolt on parts, I think the best example is Karner Racer car
He has a 2.2L reving up to 8.500, Alaniz competition head port work and overside exhasut valves, a hytech Header, better than j's, toda...., as costum single exhaust, hytech again, and AEM intake and a AEM AEM tunned by UL and he got 240 WHP, He has the best parts for the S and one of the best tunner and "only" got 240 WHP....

Was that ECU swap done same day? I would want to see a lot of runs on it to allow the ignition advance to optimise. I know that resetting a stock ECU will sometimes allow more power initially because the timing is slightly too advanced, and takes a while to come back down / adjust. As we know, the ECU will lose its learning with a loss of power to it.
Also, if its only the AFR that is different between the ECU's (I think they changed the fuelling to make the VTEC changeover less pronounced on later cars) why not just stick with your existing ECU and use the VAFC to do the AFR. Obviously the only thing you cant do with the VAFC is the timing, but surely the older / newer ECU's cant have that much different timing?

We wont know jack until we all dyno. 
very true. right now were all just throwing out numbers. The topic about the ecu swap. I think he saw that increase of power because he was revving higher, and the f22 will make power all the way to 8500 before it begins to drop. I'm guessing most people are swapping to an 00-01 ecu, and then tuning with a VAFC....I'd still much rather get an EMS. You can raise redline, and have better tuning capabilities. Ofcourse the other way is much cheaper.

But he could add a Hondata gasket, lightweight flywheel, and other little things I am probably forgetting to reach 240whp. Perhaps his ECU is still inferior to a tuned EMS, that I don't know.

actually I believe he did have all these things on the car also. The only thing he needed was the EMS, but I believe the J's ECU was tuned specifically for his set-up.

00-01 ecu swap into ap2 seems to get decent gains
vafc will tune the new ecu even better

My car toda spec A cams, mugen ECU, amuse R1, HKS Header, mugen intake. 212 rwhp on a dynojet. Same dynojet different day (obviously) was 192 rwhp stock. It takes a hell of a lot to get into the 230 rwhp range IMO.
