hey can i use my old f23a1 ecu? Is their any problems that i should be aware when im doing the f22b swap? I know its a 2.2 litter but being in Alaska i cant find any f23a1 for a decent price. IS there any difference in the transmission? Any suggestion would be helpful and thank you

 

Your going to be using an OBDI engine on a car that was wired for OBDII. You're going to have to do alot of re-wiring and i'm sure the engine will run with the F23A1, but not at it's best performance. Transmission will bolt up.

 

thanks for the head up. um do you think i should just order a jdm one? Its so hard to find a low mile or at least one with good priced one in alaska.

 

Just get a JDM one, that will be your best luck. It will bolt on correctly and will be a straight drop in.

Just curious, what happened to your old F23a1?

 

I just bought an accord for my DD and its eating oil like crazy. Cel came on for vtec- checked oil level and its almost out. I just change the oil like 3 weeks ago and oil is almost gone. My car is smoking more than usual at the exhaust, so I'm expecting a blown piston ring.

 

Hold on a sec, what year is that F22b1 from? They aren't all OBD-I.

If it is OBD-II, then I believe you will be fine with the stock harness/ECU. I know others have used a F22b1 harness for a F23a swap.

Before you go through the trouble of replacing the engine, what troubleshooting have you done? I'm not going to say with certainty that it's not bad piston ring(s) because I'm not there and haven't seen it, but don't jump to conclusions.

Have you checked things like the PCV valve? That can lead to excess oil consumption if plugged up. Have you checked everywhere for any oil leaks?

 

the f22b is from a 96-97 accord ex, I have recently replaced the pcv valve with those from auto store. i dont kow if they work as good as oem but i did replace it. IS there signs for me to tell if the piston rings are bad? i have never been in this situation before, I guess previous owner must of have neglected. The car runs perfect, no idling. It does smoke more than normal car that i have seen, Like from the tail pipe.

 

Yeah see, the Accord (as well as all other cars) switched over to OBD-II after 1995 under federal regulations. So that engine should be OBD-II... unless for some reason it is a replacement engine from a 94 or 95.

If you have replaced the valve, and it has been confirmed as working, then that's fine. Besides, the symptoms sound more serious than just a PCV valve (the major smoking is the main clue). Your symptoms do point to bad rings, so you are justified in thinking such, but I'm just trying to help you save money and time by confirming this engine should be replaced/rebuilt.

It is blue-ish smoke correct?

 

Thank you. I really appreciate you trying to help me save time and money. It really sucks, cause i just bought the car. Being honest i cant tell you if its blue-ish smoke or not. I have never seen blue-ish smoke out of a tail pipe. I've been doing some research and my situation can be refer to bad valve seals or bad piston rings.

 

I was just guessing it was a 94-95.

My mistake on that part .

You basically answered his questions hah.

 

Wow, that is a s#@t deal.

Can you tell what the smoke looks like that is coming out of the tail pipe then?

Blue-ish = Oil
Black-ish = Fuel
White = Coolant (except for cold-day startups!)

Yes, bad valve seals can cause your symptoms as well, but with the amount of smoking you are talking about, that is less likely (unless both ring(s) and valve seal(s) are going bad at the same time, or the valve seals are farther gone). When they start going, you might get some blue-ish smoke on start up, but usually that's about it.

 

so just to confirm will the f22b1obd2 be plug in play for my 1999 honda accord lx? DO i use that auto tranny or do i have to use my f23a1 tranny? Switch any sensors?

ill try to get a video of my smoking tail pipe.

 

Yes it is basically just plug-n-play. I can't confirm 100% on whether EVERY wire will match up to something as I haven't done this swap, but it will run and all your main connections should be fine.

You need to try and use the manual, as if you go with the auto you'll need an ECU that supports it. Also, the manual is sooooo much better, so why not use it right?

 

I was just gonna say not all F22B1 are OBD1.
