Default ecu decision for jdm h22

so i got my prelude up and running finally, had to chase down a few ground wires and such
i am having to run the p14 from the h23a1 i orginally had since the p13 i got with my engine was dead
i looked up some ecu's on phearable.net and they have a p30 for the jdm vtec engines
it has knock sensor disabled i can get launch control with it and it has some other cool features

but would this be a good choice, the p30 since my h22 is jdm?

Why not go with a p28 chipped ECU? Thats what I'm running now with my Hondata S200. I know that the P30 ECU came from the Delsol VTEC model, but I don't hear people chip them too much around here. Mostly P28 & P72s are the only VTEC ECU that are commonly chipped for GSRs, B16s, and H22s.

well i was think about the p28 but someone told me you cant run it with the jdm h22's since its a usdm ecu, which i didnt think that was true
so yea ill probably go with the p28 i need somethin fast i hate runnin the p14, no vtec, fuel cutting off and such
suprisingly it isnt pinging but i am runnin 93 in it

P13 ECUs are pretty much junk unless you are trying to BAR the car. I would go either P28, P30, or P72 programmed for your new H22 Motor. Perferably P28 as they are simple and seem to take the programs really well.

Driving around on P14 is just a ticking time bomb.

Your engine is going to grenade sooner or later

How so? If it is stock, and he is running the H22 injectors, he won't be running it at high rpm, and the fueling will be very rich, and retarded timing compared to a stock H22 ecu. It would be in between running in limp mode, and a stock tune.

I ran my H22 on my P14 for a few days until I got my P13 ecu in, with no issues. Engine is running hard and strong with great compression years later.

You can also go with the P72 chipped ECU with an H22 basemap so you can still retain your butterflies for lowend power. P28 will disable IABS and Knock Sensor as well as EGR, and I don't have any of these due to P28 ECU.

so anyways if i dont care about the knock sensor and all that
about how much would i be paying for a p28, and will it run good with the h22a or should it be chipped, or a basemap put in?

If your engine is still stock, I would just try to find a US P13 ecu, you know the tune will be stable, although stock, and you won't have the jdm speed limiter. I think I bought my P13 for 130 bucks, plugged it in instead of my P14, warmed her up and smiled ever after.

WTF?

Go run your h22 on a p14.

Good job.

what do you mean wtf
is that the only reasoning you have behind as to why i shouldnt run my h22 on the p14 cause well i guess mine is living proof and his and plenty of other people that they can run on them
ive had no problems
just doing lower shifts, no pinging, backfiring, nothing at all
this is just like the thread where the guy with the boosted h23a f'd a cylinder wall up and put jb weld in there, honed it and drove well over 10,000 mi on it and still no problems

anything can happen with cars so whats so bad about the p14 id like to hear your reasoning

Running you h22a on a P14 is called Half assing.

Your running a half assed engine.

Of course you can get away with it, but your still half an ***, lol.

I ran mine for 2 days while I waited for my P13 to show up in the mail, since I was sick of driving my dad's 1982 Volvo station wagon. I don't see how that is half assed, and you have given zero reason as to why it could even possibly be unsafe or bad for the engine.

As I said, the car was ready for it, I plugged it in, and I had a perfectly running swap.

Ive ran a p14 on the H22 before, and it is half assed. Bottom line...

Different engines are designed for different computers.

You ran it for 3 days, someone ran it for 3 months.

Its like Butt Connectors for wiring, lol.

Butt connectors do the trick NOW, but down the road they **** it up.

Ok, that makes more sense. Making that differentiation between a stop-gap measure, to not be riding the bus or walking, and actually planning to run the car as-is for an extended period, is a very different point.

I compared driving on the P14 to driving in limp mode, as it essentially is. Lower rev limit, lower timing advance, etc. With injectors that flow more than the P14 thinks, it also runs rich, which is MUCH safer than lean. Working as a valet for a few years, and seeing how many people drive around with much worse issues going on, I accept this as something ok to deal with, for a couple of days, maybe a week till payday or something.

I have the impression that the OP plans to get a proper ecu/ tune for the car, and would suggest the P14 as an acceptable option compared to the likes of a P28 or P72 untuned. I say this since the engines are so similar, un like the H22 from a B16 etc.

CN: We are on the same page, get the right ecu in the car.

So true.

I actually had some guy in a big Chevy truck ask me all about my car and if I wanted to race him, in the 2 days I was running with the P14, I was so sad to decline, but got a good laugh.

oh wow youre hillarious arent you saying im half assing it, actually for being only 17 and getting the motor out and the new one in and everything hooked up and ready to go within two weeks and done the right way
well sir i dont think thats half assing it, its just youre forgetting the fact the p13 that came with it is dead, and im paying for college **** right now so therefore its called being broke
and honestly idc what you think i love my prelude, and my fresh jdm engine and lsd tranny so stop being a hater

what all do you have done to your prelude that makes it so special?
cause i gaurantee when i get the new ecu my lude would most likely keep up with yours easily
i beat 4g63's with bolt ons all day with my old h23a1 and the damn thing had crank walk so i could imagine what my h22a will do

i ran my h22 with my p14 for about 3 weeks, never pushed it cause i knew it was the wrong ecu for it. duh, the reason i did because i needed the car and didnt have the p13 which i knew needed to be there asap. got the p13 in there and its fine. Yea of course i would not recommend driving with a p14 on a ecu but in my case it was an emergency. if you plan on just using the p14 forever then you got issues.

I started up my JDM H22A for the first time with a F22A Accord 5spd ECU just to see if the motor will crank over, and yes it did.

On the real though, I did ran a virgin p28 ECU for couple weeks til I got my P28 chipped ECU with an H22 base.

Look @ my sig for ideas.

What ever man. Im not here to sympathize with you about what your doing.

I really don't care to much that you are running your motor on the p14. Ive said what I think on here, you don't even have to listen. After all your only 17.

I hate nothing, but laugh at idiots and retards.

Im sure that body kit in your avatar gives you 50 more horse power.
