Default Anyone with Borla header and CEL, did the ECU recall fix the CEL?

When I asked my service writer about what the ECU recall did I was told that they essentially adjusted the range that the ECU accepted from the O2 sensor. Basically this was supposed to make the ECU less picky about the O2 sensor and make it less likely to throw a CAT inefficiency CEL.

I wondering if anyone who has a borla and has been getting the CEL has had this problem solved with the ECU reflash?

I've got the Brullen headers, and it did make a difference.
The CEL comes on much faster now after a reset.

Probably not the answer you were looking for.

I did do the ecu recall, and after time the computer did adjust to the headers, but however during the winter months when it is colder out i still get that CEL.

Header wrap is your friend and usually will keep the "cat efficiency" CEL at bay. Wrap that rascal! Plus by keeping more heat in the exhaust stream this keeps exhaust velocity up, and you make more power! Not that you'd notice it, but it's something nice to think about when the incessant itching from handling the wrap (from the fiberglass in the wrap) makes you want to cut the offending apendage off.

I have the Borla Headers and did the ECU recall fix. while the car drives much smoother now (bye bye hesitation) it still gets the CE light. BUT i don't think it may be a "Cat efficiency" code as more of a Cooler exaust temp CE light. Nothing to worry about, but header wrap will probably work.

anyone know if the Wrap will effect the warranty of the Header?

ok. I know.

I would not wrap the header because then you will void the warranty. What
you can do is check for leaks and make sure the bolts are torqued correctly.
Then you can disconnect the negative side of the battery for a 1/2 hr to and
hr to reset the computer. If you have anymore questions please feel free to
contact me either by e-mail or by phone (877)462-6752 ext.212.

Thanks,

So... I'm not wrapping mine.

That same guy told me to wrap my header. What is the date on that email?

During the ordeal of getting my header replaced due to cracking, I spent a lot of time with richard on the phone. In the end they ended up including a 50ft roll of 1 inch header wrap in the box with my header. He told me that domestic guys have been wrapping headers for a long time and stainless steel wont rust.

I wrapped my header and you better believe I will make them warrenty them.

PS it got rid of my CEL also. even in the winter.

Today.


hmm.

I'd like to get rid of the CEL.

You'd think it would take a little while for the CEL to come on.. but it was instant. I'm wondering if I didn't screw up an O2 sensor. Gotta get that code pulled.

I have a buddy who had the borla gen 3 headers I think. He had wrapped his, and got cracks. He got a new set, and was told not to wrap them, and that was the cause of the cracking.

Whether that be true or not....I don't know.....but I probably wouldn't wrap them.

ILP Check Engine Light Fix

ILP Performance has a solution BUT it may not be what you are looking for if you want the actual reason your check engine light is on fixed. It's an alternative though. I hate CE lights too.

I had the ecu reflash done, and it did nothing to stop CEL's.

In august, I put on a cobb hi-flo cat. Since then I haven't had any CEL's. At first I thought that the light had just burned out. But when I go to start the car it lights up.

I'd like the problem fixed.

I think I may have stretched a wire for the front O2.
Didn't see it when I went to drop my exhaust down. Oops.

The problem is, is when you open up the exhaust the output voltage of your O2 sensors drop. I believe we get a 420 right, cat inefficiency code? Meaning probably the difference between the 1st O2 and the 2nd O2 voltage is too seperate. You could just grab a DMM, and measure the voltage. Then do it on a car that gets the CEL. The just put a potentiometer tapped to the signal line to the CPU and to power. adjust the pot to bump the voltage up if needed. If it has to go down, run the potentiometer to ground.

Just to add; this is just a suggestion, it may or may not fix your problem. Splicing of wires is required, I take no fault for you dickin up your car.

P.S. when I get back home from my business trip, and I have the cobb full exhaust to put on. If I get a CEL, I will try what I wrote above =)

Could be a noisy signal too. If someone could take a trace of this signal on a good car vs a bad car that would be sweet. Most people dont have trace saving O'scopes though. They expensive.
