Emissions check OBD Error - help
I recently went in to get emissions checked to renew the plates and it failed.
The car is lightly modded. Catback exhaust, ets hfc, and a stage 2 cobb ap ots map. Results from the check are
OBD Communication: Fail
Reason: Cat. Conv. Unsupported Programming Error
Not really sure what that means and how to fix it.
I have the rear o2 hooked up and read some threads with people passing without issues with the OTS stage 2 map.
I haven't been able to find much on cat. conv unsupported programming error though. Any help appreciated.

Just did my inspection 20 minutes ago and passed! Car is with ap v3 map 1 v403, k&n drop in filter, turbosmart bov, megan racing catback. Nothing was uninstalled smooth as a butter, NY state inspection.

and if it is heavily modified? I'm not trying to be difficult I'd just like to learn. To understand what I'm seeing in ECUFlash. or if you can point me in the right direction I could just read the information I need

If it's heavily modified then the stock tune is not safe for it to run on, which will damage the engine
