I asked this in the tech forum, but since this is "EG+ / Del Sol" related, I figured i might get more responses here...

Anyway, I just recieved my carsound cat from IPS racing today, and I noticed something about the o2 sensor bung that was different from my friend's carsound cat. The positioning of the bung is towards the rear of the cat, right next to the triangle flange of the cat. On my friend's carsound cat, his o2 sensor is placed right on the heat shield, closer to the front of the cat. Both my friend's catalytic converter and mine are for a 99-00 Civic Si. Is the positioning of the bung in the proper place? Will the o2 sensor have enough length to reach over? Here are some pictures of the cat. Thanks

 

Which model is that? Must be new....

I don't know if it will be long enough but it shouldn't affect performance.

 

all the after market cats for the 99-00 civic si's and ex's have the O2 sensor after the cat, none follow the factory style and put it in the middle.

 

not too sure of the model number, but here's what it says on the shell of the converte...

CA/CE 93506

09/03 40386

thanks...

ok thanks. so now the question arises... will the sensor be long enough to reach over to the bung's position? thanks

 

never know until you try

I'm not sure about that either, since I still have a stock cat. Ther person I know who put in the aftermarket cat didn't say anything about extending wires.

 

Don't extend the wires just find your O2 sensor wires (should be wrapped up in black stuff) cut the black stuff and then pull it back there and then put some wire loom over it.

 

If it doens't reach just extend the wires. It's not a big deal!

 

Another alternative, but more expensive. Convert to OBD I and elimate that sensor all together.

 

Converting to OBD1 would be illegal for emissons, and with a Si, what OBD1 ecu would you use for a B16 engine?

Especially now that you have to plug up to the OBD port in the 96 and newer vehicles (at least we have to here).

when I changed over to an ex aftermarket exhaust and test pipe my secondary o2 didn't reach either.....I had my mechanic extend the wires for me....or do it yourself if you have electrical knowlegde.
just need extra wires and splicing ability LOL

EDIT: my cat(test pipe) actually had the bung in the wrong position too...before the cat, which caused me to have to buy a o2 sim

 

I used to have one back in the day, don't quite remember the part #, but i can say that i did NOT have to extend the wires.

 

i bet it will reach fine...theyre pretty long

That's true, but to some that's not a concern, but as for what OBD I ecu's can be used with a b16. Best IMO would probably be P30 & P72. You can also use P28, and P61 but I believe there is some modification required (chipped to run DOHC).

I just experienced this with a 97 hatch I just bought from Georgia and shipped to me here in CA. Not a big deal... I thought it was kind of interesting though. They connect a computer to the inside of the car to check for all sensor, and to comunicate with the computer to see if there are any check engine lights stored in memory. Passed no problem, but I always get nervous when smogging a car.

Civicgirl114: what is an o2 sim???

 

looks good to me.

 

bump, because i worked hard on this reply and i want to make sure people notice.
