Need help after thorough troubleshooting
Hey guys,
Bought my 06 a6 c6 with full billy boat exhaust headers back already installed. Engine light was on for p0430. I tried to just change the passenger red o2 sensor and reset the code. The engine light never came back on but the catalyst and evap never turned to a ready state after over 450 miles me 10 cold starts and gm instructed drives. After research on the forum I found out it was because the rear o2 sensors were pushed further downstream tripping the code. Obviously not wanting to put the stock exhaust back on I took the car to New Era Performance in Rochester ny today and got it tuned. The catalyst is now ready but I drove it 150 miles home and now the heated o2 sensor and o2 sensor and evap are not ready. My tuner told me he turned off the rear sensors behind the cats. Knowing this, will the htd o2 sensor and o2 sensor ever be ready? He told me after I drove a little bit the car would pass New York inspection. I need someone who actually has a strong idea on if the car will ever be ready or any steps I can take. I'm desperate to get the car inspected at this point and need some good answers. I bought from a dealer in Nj and they inspected it there but is not transferable to Ny. They shipped me the stock exhaust to cover there own ***. Hoping to get my corvette experience back on track, starting to not want the car anymore.

I haven't messed with HPT in a while, but I am pretty sure that you can configure the tune to have any emissions-related "tests" be ready without any driving. If I recall, you need to make sure the "tests" indicate that they are "complete" under the DTC/readiness state tab in HPT. OBD emission related items under the Diagnostics tab need to indicate "enabled" and "no error reported," which I *think* is selection #3. It wil be obvious when you have the program open in front of you, though. I thought that most states allow at least one "non-ready" reading and you could still pass, but maybe not...

A tuner can set any code to be "not reported" to the ECM PERMANENTLY---In concert with doing that the readiness tests will immediately read "ready "PERMANENTLY
Make sure they turn all the rear 02 sensors and catalyst monitors to say not reported--If you are getting air injection codes do the same (common with LT's) or any of the EVAP codes You can make ALL the readiness tests show READY permanently with a tune
