Anyone tried a p12 ecu in their accord?

[jdmwannabe]

I have a GTech Pro, I am either buying fog lights or a p12 next month, depending on my paycheck both. If I buy the p12 I will do a test and see what kind of power I come up with.

I have a stockish F22a6 and tested a P12 on it before I sold it to a member on here. I really don't think I was imagining it, but I even felt a small gain w/ faster revability over the PT6. I think that if the P12 does have more aggressive ignition timing/leaner fuel maps, then you should in theory see a small gain over the PT3 or PT6. I'm not sure if on the PT6, there are changes in the timing/fuel after 4800 when the IAB's open where-as the P12 wouldn't, and therefore would suffer on the high end??? But my A6 revved alittle quicker and more freely I noticed.

well i wouldnt think the P12 would work on the F22a6 due to the fact that the P12 isnt set up or IABs beingthat it only came on the f22a1. but the fuel map should be different regardless.

Did any ohter Honda have the F22a6 with a p12 ECU? Hopefully they have a p12 with the butterflies....

the prelude ws the only one to come with the p12 and the motor it was for didnt have the IABs on it. remember. it had the F22a1 in it. not the a6. so it didnt have the hook up for the IABs.

[SuperTuner12010]

So how could us f22a6 guys do something like this? is there an other ECU that would be a greater benefit?

about the best you can do is get a chipped ECU. or just keep the pt6 ECU you have. thats al you can do work on the parts on the a6. bore out the TB, get a port and polish, I/H/E.

It hink I may just get a 232 regrind, H23 upper pluenum and leave at that since I plan on getting a H22 in the future...

well if you plan on getting a H22 in the future dont worry about spending money on the F22a6. sav it for mods you might want for the H22. but if you want power for right now, do what you stated above.

i dont know if this has been covered or not, but what if you have an F22A1 accord, would putting in a PT6 ecu from an A6 be just as good as a P12 prelude ecu and give you the same HP boost or not. and if not, then wouldnt putting a P12 ECU in an EX-R have a better effect on the A6 (other than the IAB control) ?

I put a p12 in my a1 today which I bought off another member replacing my pt6, at first there wasn't much of a difference, but after driving around for a while I could def feel a difference. if you own a a1 get a p12, it works better then a pt6. period

as long as you have the f22a1 or a4 then getting the p12 will be of some use. but if you have the pt6 with the f22a6 then swapping out for a p12 will be pointless. the pt6 ECU controls the IABs in the intake manifold on the f22a6. you'd be losing power than gainning due to the fact that the IABs wont open(someone correct me if im wrong).

no no no no no, this is a very common misconception with people on here. It is not a smart idea to run the a6 ECU in your a1. All it does is remove the speed limiter and make your car run rich. But how often do you run max speed in your a1 where the limiter would even make a difference? Also, the a6 has a completely different cam than the a1, therefore the ECU in the a6 has been programmed to run that cam. If you want power from your a1, don't expect an ECU to give you balls horse power. It's expensive to play with cars. Buy the a6 cam, and intake and exhaust manifold, THEN run the a6 ECU.. even then, that's too stock of a car to require a chipped ECU I think I read someone else mentioned as well.

would it be better to just run with the p12 ecu in the first place? say if you plan on just getting the p12 than h23 IM/TB, a4 headers, than a6 cam would i keep the p12 or by the time i hit the a6 cam i should switch it to the pt6?

What I want to try is using a p12, A6 cams, A4 exhaust manny, and then use a shift light as a way to control the IABs on a A6 intake manifold. The shift light is adjustable, so you could just wire things so instead of a light coming on, your butterflies would open



As an aside, I am selling the P12 off of my Prelude... Link in my sig...
