I was talking to a friend and he was saying that my car has the obd2 it has two o2 sensors one in front of the catalytic and one behind it and i was going to get a pipe made from the end of the headers (The collector?) all the way back to the muffler but this would leave the second o2 sensor undone and thus my car would run rich/lean correct me if im wrong please. anyhow i was just wondering what is need to convert to the older obd1 so that you can bypass the secondary o2 sensor? thnx for any and all replies

 

dude its more complicated than that, you will need a obd-1 ecu and an adapter cable jumper for it, like skunk2 has for the gsr's, but no one makes for accords

 

An OBD 1 conversion would be rather pricey.
You're best bet would probably be to just put a bung on your new pipe to accept the second O2 sensor.

 

if im gonna run N/A with the car would it reall matter about the obd1 obd2?
or if i make the pipe a "bung" for the second sensor and everything hunkey dorey

 

OBD2 tends to keep your car close to stock spec, and thus your mods would have less pronounced effect than they otherwise would on an OBD1 car.

If you adjust the a/f ratio too much with a piggy back system like the VAFC, it'll go into limp mode..

 

so if i convert somehow ill get more out of it then if i leave it.
whats limp mode?

 

To go OBD 1 you need a OBD1 distributor off of a h22orh23, OBD1 injectors, AEM fuel rail, OBD1 ECU (www.hondata.com has info on what other ECU u can use) and a shop that knows how to convert the car to OBD1. With OBD1 ECU you can get it programmed later down the road and there are 5th gens that show an increase in power after they converted to OBD1.

 

That's at least a thousand bucks in parts.
Ugh I don't even want to think about the total price of my OBD II to I conversion.
Somewhere in the neighborhood of $2K, 'cause I used all-new parts, oh, except the ECU was used.

 

You can find used injectors and distributors online or at the junk yards. If you need cash start selling your old engine mods. If the shop does alot of swaps more than likely they will have spare parts and won't mind trading your OBD2 part for a OBD1 part. I was lucky enough to find someone to trade with who had an OBD1 and needed OBD2 parts from my 97h22 so we just swapped. If you really want to keep it simple stay with the same OBD as your car.

 

well for one running with out a cat where i live is legal and two im mean yea 2 grand is alot but if im gonna do a project
them im gonna do it right and if i have to convert to obd1 to squeeze all the power i can get outta the car then ill convert.
thnx for the info guys.
