    ROFL...I can't stop for some reason...

    well, I guess I'll have another Mickey's. WTF was this thread about again? Oh yea, CAT delete code. Diablo will take care of it. I didn't know the car still threw the codes and the Tool kept them from appearing in my car until I had a "misfire" code the other day on startup...I hooked up the Tool to see what the alluminated code was and noticed the two codes were there for O2 after Cat sensors (or whatever it was).

    I was throwing the CEL quite freqently. I then got the Predator and was able to turn off the rear 02's, thus no more codes. But with the rear 02's turned off the OBDII inspection will see them not Ready and fail you for it. Josh was able to leave my rear 02's turned on and change some variables when he did my CMR tune and I haven't thrown a CEL for the high-flow cats since. So it appears that the cat-inefficiency code can be tuned out with a CMR tune, but some higher modified cars maynot be able to do this. So what I'm saying Stevo is that you might be able to someone to do a custom CMR tune for ya that will leave the rear 02's on and in ready status and not throw the CEL.

    Steve this blows, I thought the Magnaflow cats did not throw codes. What catback are you using?

    I want the Magnaflow Hi flow catalytics with the Corsa catback.

    yeah man....

    I have the stock cat back....with the resonators and mids cut out....and replaced with just Flowmaster mids

    i would be willing to bet if you have a full corsa catback w/ mids and resonators that it wouldn't throw any codes

    I will be using Corsa's full catback system with the Magnaflow cats so we are definately going to find out.

    The Kooks are notorious for popping the catalytic efficiency codes, its more the cats the header IMHO

    I had codes from my high-flow cats. When I had my car CMR tuned, they changed a setting so that they don't throw the code any longer.

    I would think you could get that fixed with an e-mail tune.

    The rear O2 sensors are there to check the cat efficiency. The PCM does that by comparing the reading from the rear O2 sensor to the reading from the front O2 sensor. I'm assuming the rear O2 sensor values are stored somewhere just like the fronts are stored in the short term adaptive memory. I'm guessing the "tuning" trick is to modify or fix these values (rear O2 sensor readings) to compare correctly with the fronts. I think that's about the only option you're going to have to pass inspection without making physical changes.

    You should talk with an inspection station to see what your options are and what the inspection entails (should be able to google that?). If there's a visual inspection or they use a sniffer in the tail pipe you could still be screwed even if you fix the codes.

    Out here they have inspection places that try to get your inspection business with offers like if you fail you get to re-test free until you pass. That means that if you fail you go and get repairs (they're hoping at their place) or whatever and try again.

    That's exactly what I was running about 3 weeks ago. Never through a code with this combination.

    im going to get it inspected at the place that installed the cats...they might not even care cause they knew i was going to get the codes hahaha...

    i just dont want my CEL on 24/7 lol...so if i can chance the O2 tables to make the car expect the values that its putting through...that would be best case

    Hey Steve.....which codes do you have for starters.Is it the common 0420-0430?Or do you have something else.If its the o420-0430 you need to get the anti foulers.A very few with the Magnaflow cats will throw a cel.But if it's a different code you might have a bad sensor or a pin pushed out of the plug,which is very common.
