I need to know what ecu to us on a H23a vtec with an h22 auto trans the ecu on the car at current is the fac. org. for the f22 with the h22. any info will be a help

H23AHybridEG

So did you get your engine finally? Use a H22A chipped P28 ECU. I would get it from IH8Ricerz on here. He does a good job. However, I would also get a VAFC (or maybe even Hondata) because NOBODY has the real H23A fuel maps, and running straight H22A maps will make you run a bit lean

chipped ecu's are retarded, if you really want to do it right go with atleast something tuneable like hondata.

how is a chipped ecu NOT tunable?

iw ould rechip a p72 or mod the p28 for iab control. then have it wideband tuned to your car.

Dude, when is everyone going to stop all of the bullshit about Hondata. Any idiot knows that if they have the money, it's what they should get.

However, I believe the original poster is probably more concerned about getting his car up and running than hearing the same old "buy Hondata" bullshit.

And I'm obviously not talking about some gay-*** Skunk2 or Mugen chip. I'm talking about chipping a P28 ECU with the stock H22A program so that he could use it with his engine. Who the hell cares about a 9,500 RPM redline?

I have the same engine (I assume) as the original poster does, and I'm using a chipped P28 with a VAFC. Check out my dyno charts if you'd like to see the results...and that's without IAB control

Thanx man well actually its a lil of both i know i ca go with hondata but if i wanted to tune it my damn self i would already have it but it dont i want it dont so i cdont have to fck with it. n why the p28 n not a p13?

Qfactor

I would use the P13 and run a KS-rom or Spoon for that H23 of yours.

You said it not me.

If no one has them and the h22 maps arent a permanent solution then another solution is hondata or aem ems.

If you have the money to do some fricken jdm h23a then you should have no trouble buying the right fuel management. He should of thought about all of this before he bought it.

...basically what im trying to get at is if you can have that p28 dyno tuned then go for it. Doing guesswork fuel maps for any engine is retarted

The P28 is easier to work with and if done right, you won't get any CEL's while using it. Granted it has no IAB control, you can still get it to work. Just do a search on here. Check out my dyno chart. That's with a P28 ECU amd a VAFC. I got some NICE results

leprekhan

Lets clear a few things up, $ not a problem, dont want somin we got to dyno tune cause i dont feel like driven to a dyno, i want the 99 JDM Accord SI-R ECU. where do i get it? we are just gettin it runnin first. Its on the lift in the trans shop rite now n it would be to drop the rite ecu in it when it comes down.

Not to add to this pissing match, but a chipped ECU with VAFC will never be as good/better then a EMS (Hondata, Uberdata, AEM).

Plus, Uberdata is cheaper than your p28 with VAFC

I know i could use a EMS i want the OEM JDM ECU. this is a blue top vtec not a frankenstien, who sells JDM ECUs?

****...too bad I sold my JDM H23A VTEC ECU on E-Bay a few months back. I would've given you a good deal. My question to you is why would you actually WANT to use that ECU?

Dueceification

Hondata is nice but the blue box is gay!!!!! Like my man says F*ck the blue box. If you are near AZ my boy tunes p28, p72 and many more. He uses his own software that he made. It's better then ubderdata and all that crap. A chiped out ECU can be reprogrammed if they did not solder it in. Which i see is very common in p13s for some reason.

H23AHybridEG

Why? Because it would be much cheaper and less of a hassle if you just used a P28 ECU with Hondata or a VAFC. The H23A ECU is OBD2, so you're going to be messing around with the distributor, injectors, and wiring. But if that is what you must do, then more power to you! However, I wouldn't suggest it...

Please do not use VAFC on a stock P28 or even chipped. Uberdata is cheaper and a **** load better.

leprekhan

i talked to the ecu man yall suggested about gettin the p28 n he told me good luck cause of the auto trans come on ppl one of u has to know something

Katman

bickering about chipped ecu's aside....
I have a couple of totally stock 4-plug AUTO JDM OBD1 P13 ecu's on hand if your interested in one.

PM me if interested...

and uberdata is just a program used to chip your ecu....

H23vtecEG

i have a program from my old h23vtec uberdata. tunned to perfection. IM me if interested.

AccordGuy93

Im trying to run a H23A Vtec with my f22 auto trans.
my buddy gave me a p13 auto ECU. I was plugging the wiring harness all back up after swaping engines and realized the knock sensor was broken. Hes telling me the p13 ECU doesnt have knock sensor, so i wont be able to run a knock sensor.
I've been looking everywhere online trying to figure out which ECU i need for my build. I cant afford a standalone ECU, or hondata. I was told everything was going to be direct fit and work good, but a car without a knock sensor isnt good. I dont understand why i cant just run a h22a4 vtec auto ecu from a 98 prelude. Im using the 98 prelude dizzy and car is obd2. Would h22a4 ecu work? If not which one could i use for the car to just run safe and efficiently?

Hey, new to this forum just found this post.
I have a 93' H23a non v-tec lude and I want to swap to H23 v-tec.
Which ECU do you recomend? P13 or Hondata S300? I've read you have to switch from OBD1 to OBD2, is this difficult?

Thanks in advance
