Im working with a tuner that won't shut them off and I respect that, everything else they've done for me has worked great. So he has my business. Just trying to figure out how to go catless or use a 200cel race cat.
I can get through the sniffer inspections here in my county but I at least need the appearance that there is a cat on there. So thats not an issue at all. Since its a 5th car It won't be driven much and not worried about it killing polar bears or some amazon frog.
My turner states the rear 02 is used for trimming and car trims to the cat. On a scanner looks like the rear 02 is pulling about .7-.8 volts all the time. So wouldn't an emulator work? I can run that at the same level and it would appear all is normal to the ecu.
