what ecu to use on my H series??

[cb7accord_h22]

I have a slightly modded h22a im running the p13 now what would be the best ecu for my set up?? the p28? or the 72??....anybody tryed anything else on an H series?? let me know what you did and how it worked for you

[The G-Man]

Anything chipped for VTEC will work. p28, p72, p06, etc.

thanks, any one beter though?

no neither is really better than any other if your going to be using the same map.
i would suggest getting the car tuned if u get any of those chipped ecu's to get the full potential out of the car.

Its depends what kind of mods u done, If u just did a intake and exhaust then u fine with the p13. If u change like the cams, and injectors, then u can get the p28,p72 or what ever, and use those ECU for tuning. HOndata would work far as tuning

what about a stock h22a4, would a stock 97-2000 ecu work? Cause I have one of those and a friend has a coupe with a h22a4 swap going into it!?

Read this and youll understand.......

..... i just got done reading this and i understood it, its great for people like myself who wanna learn about ecu's

You could try. But there are a couple of hurdles, wiring of OBD-II, and I think those ECUs have an immobilizer in them that takes a signal from a specific key.

the p13 is the worst ECU to use. it looks for a knock sensor, which means it will most definitely retard the timing for no reason at all and cost you a few HP, while not protecting your engine from detonation anymore than a p28 or p72.

you don't need the IAB wired to work. wired or unwired, there is less than 1hp difference at any point on the powerband. the p28 can have a switch to run the IAB and the p72 is already capable.

the p28 doesn't look for an EGR and the p72 still has a knock sensor.

a chipped p28 will net you more power than anything and will be cheaper.

the p13 is kind of a half between an obd0 and obd1 computer.

i'd get the p28, chipped for an h22a, and run with that. no knock sensor or EGR to worry about, the IAB setup doesn't do a lot, and it will be the cheapest option.

Explain how a p28 would be better, and cheaper for that matter.

Don't include "hook-ups" because not everyone has access to them.

Every p06 and p72 I've seen are cheaper than p28's.

When an ecu is chipped, it makes no difference what kind it is.

Virgin P28's are getting hard to find and a chipped one will cost ya. You could probably find a Chipped P06 with VTEC and on board IAB support added (no activation switch needed) for under $150 (I did my own for under $100) It works as good as any other ECU. Hell between all the chippable OBD1 USDM ECU's there are only two main board versions. If the board number is the same it has the same silkscreen lines running on it. No matter what the P# on the box is. All you have to do is add a jumper here and a resistor there, and maybe a 5151S High side switch as well..... and you can have it all!

1. As long as the ECU is chipped for VTEC as mentioned.
2. P13 is fail.
3. It doesnt matter which is "best" Either way all of them have to be tuned to run right. And no a basemap does NOT count.

[flight50]

Nail I am assuming your no.2 you meant fair and not fail. The p13 can't possibly be the worst. Its the stock one that came with the h22. basics, the p13 should be fine. just a little tuning needed. but the real question is not what you have for say, it what your future plans are going to be. don't waste money on something that you will have to upgrade to in the future because your mods won't be valid on a weaker ecu setup. do it correct the first time. also you didn't mention the drivetrain. i am assuming you have a 5 speed. if you have an automatic, then piggybacks sys are pretty much out of the question.

[98vtec]

running on chipped ecu's is a complete waste. Tuning is REQUIRED.

[d112crzy]

The highly depends on how good the basemap is with your car. The same basemap will run perfect for one car while it will run horrible for another.
