What ECU?

[HardInThePaint]

Yo I needed to know what ECU is used with the F22 DOHC. Right on.

idk what one they used in japan but a p14 would work.

Is that the ECU for the H23? And would it work to its full potential with that ECU?

[5gwagon]

yea thats the h23 ecu and from what i read altho by no means am I an expert they are essentially the same motor

P14 is the H23 ECU, Yes it will work but you will have to wire in a knock sensor.

The actual ECU fro the F22B DOHC would be a P39. They are fairly rare though for what I have seen.

I would look into finding a p06 ECU and get it chipped and have a base map burned onto it. then get it tuned by a tuner.

They aren't all that rare in Japan... just over here, where we didn't get that engine!

Is that p14 the H23 ECU for auto or manual? Or is there a difference? I need auto.

u can use a integra b20 p75 or a h23 ecu

What the fuck? NO! You cannot use an Integra ECU without considerable modification to the ECU. Please don't give bad advice on my forum.
Additionally, the Integra never even got the B20... that's a CRV motor.



The ECUs have the same code if they're auto or manual. There is something further in the code that says what it is... but the best thing to do is just ask. I don't know exactly how much difference it makes, since the TCU controls the transmission... but I'd get the auto ECU to be safe. Additionally, you'll want the TCU as well, so you're not shifting earlier than the motor needs to be... or you'll be missing out on the high end power.

When I swapped to my F22B DOHC I used a manual p06 ecu (chipped w/a base map burned to it though) and I was still auto and it worked out fine FOR ME.

I have heard of other people NOT being so lucky and using an auto ecu on a manual or a manual ecu on an auto and having shifting issues AND motor issues.

It could have been from the tune or maybe just a freak ecu. I don't now.

As Deev said though, I would use an AUTO ecu for AUTO and a MANUAL ecu or MANUAL just to be safe.

If you're going to search one out anyway, might as well find the correct one

When I looked for a P39 for my sister's car I didn't have any trouble finding one. I was not expecting to find one because everybody always said they were hard to find. Of course, your millage may vary.

[HardInThePaint]

Aiight, wish me luck on finding the p39. If ain't none available then I'ma go head and snatch up the H23 ecu. Right on yall.

i know this is rising from the dead but....

benj....

you said you had no issues finding P39's, so I gotta ask where you found them?

Much appreciated!

Auto VS. Manual: anything greater than 50 is auto, anything less is manual. Example: 37820-P12-A11 is manual 37820-P12-A51 is auto. Manual #'s I've seen have ranged from A00 to A11, and auto I've seen A50 to A52, but I'm sure there could be more. I've also seen a JDM P13 that didn't use an A, but an N, so it was 37820-P13-N00, maybe the JDM ecu's use an N instead, not too sure since I've only personally seen 1 JDM ecu.
