I have the B&B delete pipe and I have not put it on yet because I do not want the CEL to come on. I have herd that you can use a resistor and loop it on the sensor to fake it out. Is this true? What are some other fixes for the O2 sensor?

 

Couldn't wait for Perrin to fix their O2 simulator so I'm testing the Ultimate pipe. They guarranty no CEL. We'll see.

 

I installed mine yesterday... great product, great price. No CEL yet.

 

I don't understand how a pipe alone can stop the CEL? Maybe it's a heat thing and they have something around the O2 bung holding the heat?
I wish somebody would come up with a solid fix for this.

 

Oh it's a pretty solid fix, actually. It's not so much the pipe itself.... it's what the pipe has "on it". The only reason I really can't say any more is because UR asks customers not to. It's a great fix. I'll keep an eye on the CEL to see if it comes on over the next few hundred miles, but I'm thinking that it won't.

 

Got my Perrin delete cat and the CEL fix, so far NO CEL for about 1k miles !!

I don't have the fix, so I can say whatever I want... The fix has nothing to do with the pipe. So, lets start with why you get this CEL. You wanted your car to go faster so you get an exhaust with no cat. Now you have 2 O2 sensors that are reading the same voltage. That means your emission control equiptment (which you took out) isn't functioning properly which inturn trips a code in the ECU and it make that light come on. Now the only way to get this code to go away is to make the second O2 sensor read a lower voltage than the first, which would "trick" the ECU into thinking that your cat (which still isn't there) is working properly. I'm not 100% sure if just any resistor would work, but I'm sure if you soldered one inline with the return line (to the ECU) you could get the code to go away that way. Or some place online sells O2 simulators do a search. EDIT: I guess Perrin is one of those places...

 

Has anyone tried the resistor fix?

 

I have the UR pipe for a couple months now no cel it great! Can't say why but those that have them can say it works you will be surprised when you see it!

 

I tell you what... it is simply amazing what a little bit of research can achieve when you are curious. I haven't said a word.... but may I direct your attention to a pic that is found on UR's website... find anything DIFFERENT about the test pipe in this picture?

This is all I can give.

 

looks to me like the O2 sensor plugs into a small pipe extended from the test pipe.... Which will reduce exhaust gas flow over the sensor... Now you do the math

 

That doesn't help me.
I already have a B&B pipe.

 

CEL fix from http://www.bigjoshracing.com Works like a charm and is cheap at twice the price.

 

What is it? are their any pics someware?

 

The UR text pipe setup works great. I've had the thing for months now and haven't gotten the CEL for the 2nd O2 at all. The thing is quality too.
