anyone have any experience with these? i have just bought one. there's no hole for the secondary o2 sensor. does anyone have one on their car, and what did they do to by pass this?

thanks.
i've tried searching and doing some research. and it seems like the only things to do is...drill a hole and weld something on to thread in the sensor, or get an 02 simulator...can someone also clarify how these work? is there any other options?

 

Convert to ob1 !

 

I'm probably going to suspect that this wouldn't be the right place to ask since it's not directly an "ITR" specific question but here goes.

Judging by your username, aren't 95 Del Sol's OBD1? I can't see why you'd need a secondary O2. Unless you're running OBD2 which still wouldn't make any sense. From what I can see, you're probably talking about your primary O2. If so, just get an aftermarket header and have the primary O2 sensor on the header and forget about the secondary O2 sensor. To pass aircare, you're gonna have to resort back to a catalytic converter.

If in any case you're OBD-2, to reduce the possibilities of having the CEL coming on, you'd have to do create a bung to fit an O2 Simulator with your secondary O2 sensor.

yo bos dc2 I actually just bought an itr! I apologize. I realize my username and picture must have been misleading lol. I should have it gave some background to it too I guess lol. I do appreciate the effort to help as well though.

as for switching to obd1. i haven't read too much on that yet. I'll look through the site some more for more info on that I guess. has anyone heard /done some mod to the sensor with a resistor?

 

I have one on my 2000 gs-r. T1R header > T1R Testpipe > T1R B-Pipe > ITR Axleback
I added an o2 bung on the testpipe right before the b-pipe flange. Just be careful where
you add the o2 bung, you probably want the sensor to be 90 to the ground -( pointing
to the drivers side otherwise the shift linkage will get in the way.

Also just a few months ago my T1R testpipe broke at the weld. Took it off rewelded
over all welds. The welds are super clean from T1R but it looks like they dont use any
filler rod, almost look a little undercut. Might be a good idea to reinforce the welds before
installing.

One last thing, even after adding the secondary o2 sensor i still get the cel.
More so in summer months, seems in winter or colder months it doesnt come on.

 

Haha no problem.

My boss actually did modded successfully to his testpipe with a resistor on his Subaru Forester XT to trick the ECU but I don't know how that pans out with a Honda. Unfortunately I can't tell you what resistor you might need.

If you're in Vancouver, I can recommend you someone who can chip you an OBD1 ECU for a fair price but you're gonna need to buy an OBD2 to OBD1 harness (sub $100). That way, you don't have to run a secondary O2.

When aircare comes around, all you have to do is slap on your cat w/ secondary o2 and your factory ECU. Pass it and swap it back.

That's what I'm doing currently and so far it's been good.

 

Made in Taiwan!

OP - there was another T1R test pipe before that had a bung for the secondary O2 sensor. sounds like you'll have to weld a bung onto the pipe and possibly get an O2 'sim'.

 

Quite possibly the stupidest thing I have read all day.

A) OP you have a resonated test pipe not a Catalytic converter so the use of the word "converter" is more of a gimick as nothing is being converted, it is just a test pipe.

B) to the quoted post how would that be a good idea? Unless this user plans on doing something more radical than a few bolt ons converting to OBD1 would be mostly pointless at this point.

C) OP you should have bought a High Flow Catalytic converter, a good 2.5" cat will last for years and flows just as much as a test pipe, it has been proven just do a search. This way you would be legal and not face a $10k fine if caught and you wouldn't have to worry about a CEL and would be just fine with an OBD2 setup.

D) if you really must help pollute the air and keep a test pipe you don't need to convert to OBD1 you just buy an o2 simulator or even easier try the 02 bung trick, you basically mount a collar between your o2 bung and o2 sensor, this collar has a small 1/4" opening in it vs the 1/2" or so opening in the bung so the o2 sensor can't get as much gasses as it normally would to read back to your ecu. That sometimes works on most cars just fine and cost about $5

 

hey as for converting to obd1, i don't think that i'm gonna be doing much else to the car other than boltons. already got i/h/e and just want to put the test pipe on



ya i'm thinking of doing that. thanks.



a- ya, lol i just thought i'd use that name since its what t1r "calls it"
c- didn't even realize that there were such a thing...ya freaking noob over here. any brands that might be good? popped over to team-integra.net just now and saw that carsound is good? also, ebay seems to have a lot of no name brand ones for cheap any good? i'm not thinking they are. I definitely don't want to be caught by the police and fined...especially if the gains are the same.

Thanks for the all the input ppl. i really do appreciate it. Also, surprised to see so many of y'all are from vancouver too!

 

Carsound is good, just make sure to find someone who will make a bolt on for a JDM sized header, I used to make them and so did SMSP, I don't do them at this time but check with SMS products and see if he might have one.

No Ebay ones are crap and will break quickly.

 

Many years ago I had a T1R, I had a bung welded on by a local muffler shop. IIRC it cost me less than $10 to do that. Combined that with an 02 defouler it worked like a charm for years.
