Hey,

Can anyone tell me what ECU they are using in their F22B engine swap.? I have a 94 accord LX POA ecu and I am installing a JDM F22B DOHC engine.

1 Will the ECU from a single cam accord(POA) non-VTEC run the dual cam F22B?
2 What ECU is reccomended for this Engine?

I have a USDM H23a wire harness. I will be dropping the engine and tranny in the car this weekend. Any help is greatly appreciated.

Thanks

 

most people run the DOHC F22B ECU.

it is possible to use your stock ECU but i wouldnt recommend it. you wont see all the gains

the H23 ECU will work as well, but its got the knock sensor as opposed to the DOHC F22B which doesnt.


cruise HT, i remember i think 94AccordDX had the DOHC F22B ECU.

 

people have reported that the h23a1 ecu works better with the dohc f22b than the f22b ecu does. just add the knock sensor and your set to go

 

Yeah thats kinda true, the h23a doesnt have a speed govenor like the f22b ecu. I have one (dohc f22b ecu) I run it on my single cam no problems, and yeah you can use your 94 ecu, but like they all said its not as good as the f22b or h23a ecu

 

Hey Thanks for the info. I also looked at some of your archived posts and they were helpful. One more question. Do you know the ECU code for the F22B? I have the POA ecu. I found an ECU at a local salvage tard and its a P12-A52 any thoughts on this setup. That chip came out of a 94 prelude SI 2.2 non vtec.

Thanks
Again

why?

 

that would be the same ECU as a stock accord

2.2 liter non vtec prelude = f22

 

i have a re-programed ecu for a h23 that will work for a f22b dohc

use the accord wire harness in the swap

 

Why not use the h23 harness? I would have to modify the accord harness alot to match up with the different sensor locations.

 

I started the changeover today. I now understand why I need to keep the Accord harness.

Thanks

 

So I have a f22b swapped 92 prelude. I’m pretty sure the original engine was an h23a1. I’m not no sure how good the swap was though. I’ve found lots of questionable wiring. Which leads me to wonder if my swap was done correctly. One thing I did notice is the ecu is the stock p14. I believe that’s the stock one anyway. But I’ve heard people say it will not run as good with the h23a1 ecu as the proper one. I was thinking it had to be chipped or something like that. But I read it cannot be chipped. So sorry for the ranting. What I’m asking is am I really good with a p14 ecu, should I still check for a chipped board/swapped circuit board, or upgrade ecu’s?

 

Stock F22 DOHC ECU is best for a street driver.
Next would be a custom tuned ECU either chipped or a Hondata type tunable ECU.

Speed density systems cannot compensate for changes in VE.

If your current ecu is stock for an H23, then it either needs to be chipped or, if not applicable, replaced with an ECU that can be tuned for the F22.
