Hi I'm trying to figure out which ecu I can use to pass smog in My f20b swapped 97 accord. Has to be obd2, manual, and without an immobilizer. Can't use the original ecu that was in the car because it had an immobilizer Whatever works for h22a swapped 97 accords should work in this also as some of you probably know the f20 and h22 are practically the same engine.
This is ONLY to pass smog, I already have a chipped p28 that it runs on.

 

No idea what regulations you have to pass or what your test procedures are.
In Calif, you will most likely fail since no DOHC engine came in an Accord. And the 'F20B' cast into the side of the block would most likely fail you on visual.

 

USDM P13-A12 from the Prelude.

At that point I'd probably just leave it in, unless you're tuned (above a basemap) it'll be practically the same with the P28.

 

The p13-A12 are hard to find but thats what you need even if you have to buy it new from Honda

 

Alright thats all i needed to know, thanks guys!

 

Note: that ECU runs using 295cc saturated injectors, if you are not running those injectors it may not run properly. If it does run and you are able to drive around. You will probably have to drive the car around on the streets and highway for a week or so before you have to run the test! It will take that time for the ECU to even out fuel and timing to set the readiness codes.

You aren't going to be able to just drop this in and pass if they do any sort of sniff and computer emissions test

 

I think what ghost is saying is that the a12 usually goes with engines that have peak and hold injectors stock. However the f20b engine has saturated injectors. You will need to pick up some 93-96 si vtec injectors to use.

 

Are you trying to referee your car? I was under the impression that the F20b was not a motor that could be refereed.

 

I already have those type injectors.

 

Just trying to smog, not bar it.

 

Any reasonably smart smog tech will give you a visual fail without it being bar'ed.

It's not exactly a direct replacement motor.

 

I see.

 

Going to the same guy my friend with a type r swapped integra went to, didn't even make him take off his apexi headers or his intake. I'll be fine.

And plus there is countless h22a / f20b swapped accords out there, you trying to tell me absolutely non of them have passed smog?.. I've seen a bar'ed 94 accord with a f20b..

 

lol I never said you couldn't bar it, I said technically it shouldn't pass a smog test without being bar'ed.

You're talking to someone with an h22a bar'ed 4th gen accord.

Apparently you're way too advanced for me to being giving advice to.

muh bad

 

He got dat no visual hookup nomsayin??/

 

Point is you don't have to have your swap bar'd to smog a jdm engine. Maybe your not "suppose" too but we're not even "suppose" to modify our cars in general right? I don't plan to have this car for anymore then another year. I've had it for 4 years and I'm ready for something new so getting it bar'd seems like a waste of time to me.

 

8 bucks for a bar sticker makes it a helluva lot easier to sell it. Just saying.

 

Depends on the smog test! What are your states regulations?

Sure a swapped engine could pass smog. A tuned ECU can pass a sniff/smog test as well. However, it will not pass a smog where the OBD computer has to be confirmed or there is a visual on the engine and it's systems.

As far as bar certification goes, depends on the requirements and how well you know the guy doing the examination..... I think anyone could buy a sticker!

 

The engine is acceptable ONLY when the engine it is replacing is the same and was the OE engine in the car.
H22A to replace a H22A1 in a Prelude is fine as it is considered a replacement engine.
H22A to replace an F22** in an Accord is not. This is a swap requiring BAR approval here in CA.
Le sigh
We can modify our vehicles as long as they do not affect the compliance of the emissions output. Some aftermarket suppliers do us the favor of having their components tested are C.A.R.B. approved and given an E.O.# so we do not have to have our personal vehicles retested for small parts.

This can be done by a single person as well. Test the vehicle before any modifications to verify compliance. Then retest to verify compliance again.
Once CARB is satisfied it will issue an E.O.#

Then why bother with a swap?
Getting a car BAR'd is not hard, and if you live in one of the counties that requires smog testing it will be a lot less hassle down the road.

 

....Le sigh, first off all ive had the engine in my car for 2 years, so i am not "bothering" with a swap. and second, you guys say i cant bar my car but then wanna jump my **** when i say im not gonna bar it... You guys really just seem like you wanna argue about anything on this site. I got the info i needed so i could care less about your guys opinions of what i should and should not do with my car. so with that said, thanks for the info i actually did need (not lectures about laws I already knew and have experienced). Have a good day! Go work on some cars.

 

Cliff's:

Has illegally swapped engine in car for two years.
Knows a guy that will pass him on smog.
Wants to know how to pass smog...

 

Lol, I needed an ECU number. Go back to reddit and quit playing mechanic mike.

 

Nobody EVER said you cant BAR your car. Nobody.

You want to argue so you're making that up on your own so you have a reason to argue and play the "everybody comin at me" card.
