i had a p28 chipped (muegen) but it was swiped from me and replaced with a stock p72. i ran this setup for awhile with no probs ut i did notice that i pulled alot harder whe vtec with the the p28. now i'm thinking of chipping my p72 now. i did a search but i had no deffinate answers on which would be better. should i stay with the p72 or get another p28. either way one will be chipped.

p.s. the setup that i am running is I/H/E, sk2 IM, port and polish and vafc if this helps.

i would sell the p72 online if you could.. last i checked they were going for about 200 bux you can get a p28 ecu chipped for that price.. im only sayin sell it cause the if you have an obd1 p72 ecu they are rare cause they were only made for 2 years.. help some fella honda brothers out.. youd ont need the p72 ecu now cause you have a skunk2 IM and all a p72 does is control the butterflys..

btw i dont need the ecu but i know a couple of friends that been been lookin and wanting one for long periods of time so you could help anyone out online cause they have all got an ecu finally or went w/ a new intake manifold and chipped ecu

P72 also has the ability to control knock. I guess this wouldn't matter though if you were running the Mugen chip as it will disable the knock sensor as well as a few others. The Mugen program does pull pretty well, but it gets terrible mileage. My friend and I just worked on a custom program that basically takes a stock P30 unit, adds the Mugen fuel and timing maps, and even has launch control. Really nifty stuff. Best part is that so far its working flawlessly. It has corrected the common "hunting idle" issue with the Mugen chip as well as the gas consumption issue.

yeah i'd say get the p28,
why mess around y'know?

p28's arent that expensive,
look around you should be able to get one for under 100 ez
and theres gotta be someone that wants your p72

are there any other advantages of using the p28 over the p72. I know that the p72 does not have as many programs out there for it, as does the p28. i'm also looking into other programs. The mugen was nice but like stated before the gas milage did suck *** when i had it but now i am used to the improved gas milage.

B_CRUZ!

the p72 is just as chippable as the p28. get katman to chip it for you at hdmhondaparts.com and he could even add a toggle to switch from running in 'chipped mode' to 'stock mode' for smog.

never thought about that. how does that work? Might have to really consider that.

Plan B

h22 people will buy those things like they are going out of style.

I say hold out for 300. I can just about guarantee that eventually someone will get desparate enough and buy it from you at that price.

thats a pretty good idea but that does me no good if someone just rolled up on me on the street or highway and i'm in stock mode. maybe i can modify so i can switch on the fly or something.

Plan B

no, i'm quite sure there is no way to do it "on the fly" Unless you want that ecu to "bite the dust."

I accidentally switched mine and restarted within 5 seconds of turning it off and i about fuckered my p28 up. It acted crazy.

well can anybody suggest a program that is good or had eperience with one thats not as bad on gas as mugen?

I offer many. J's racing, RS Azinawa, Kouroki, even stock P30 (with KS disabled) will work very well. check my sig

instead of buying chips why don't u just get it tune with the vafc

VAFC = crap, for many reasons. One of the main reasons being that changing the Vtec point using one doesn't correctly adjust the fuel maps as well. There are Vtec fuel maps and normal maps. Changing the Vtec point using the VAFC doesn't allow the computer to switch maps, only cam engagement.

u2civic1

but u can add and change the fuel with the vafc along with the vtec point that y i said get it tuned

You can add more, this is correct. But it still isn't switching the ECU over to the Vtec fuel/timing maps. Timing is one thing you certainly can't switch with a VAFC. A VAFC is nothing more then a "band aid" fix. Sure, it will do the trick.. But not correctly.

Ya, you can't switch from using the eprom and not on the fly, it just doesn't work... now I could program it so that you could flip a switch and have it use another set of fuel and spark maps, but is there really the interest out there?
