You never had CEL's or a p0420??
I had that code on t he 1.02 map. Once I flashed to the 1.03 map no more CEL's.
Then you have a downpipe that has a spacer built in or there's something you're not saying like the dude kept clearing codes and forcing readiness until it accepted it and i bet its not a cbfa
youre not in NY. we cant pass w a file that eliminates codes. we have to have all sensors active hence going back to stock
Im in NY and have no problem passing inspection catless. I just put the car back into stock mode and put a spacer on the rear o2. Takes about 10 miles of driving for all of the sensors to go ready. Even the cat goes ready.
We have a number of customers that are able to set readiness with with aftermarket downpipes and tune.
@NLEO Thanks for that information. Do you have a pic of how yours is installed and which brand spacer? Want to make sure I put it in the right direction.
Do you run with the spacer all the time or just install it when you need to pass inspection?
Its a right angled ebay spacer. My friend gave it to me and he paid like $15 for 2 of them. I just put it on the rear o2 for a day and take it off right after the inspection. Ive found that it doesnt matter what way you put it but I run it parallel with the dowpipe with the o2 wires facing the rear of the car.
Then I just drive around with a code reader and wait till at least all of them except one are ready. Youre allowed 1 not ready in NY but usually they are all ready including the cat. It usually takes 2 cold starts to get the cat ready.
