Problem with state inspection
 
http://www.the370z.com/members/2011-...inspection.jpg

The place I go to never has an issue before without cats but now they tell me that the Catalyst and Heated Catalyst are not enabled. Not sure if that's normal. I used to be tuned with uprev before with Berk test pipes. But now with the new GTR TT and ecutek it won't seem to work. They suggested mini catalyst O2 sensors, O2 Simulator Mini Cat Cel Fix stainless steel Rear O2 sensor simulator. .

Any thoughts.

I believe Your tuner turned them off so you get no check engine light for dreaded p0300 random misfire and catalyst efficiency faults. On my supercharged car I have 2 tunes that I I flash the ecu with. One is all monitors enabled so I can pass nj inspection and other one has all the ones you listed disabled.

Interesting. I was having p0300 misfire coming on my supercharger setup. The default Stillen kit. I ended up getting the TopGunz A-A kit and it went away
Wonder if this is something I should look into, get a secondary tune for emissions testing. Thanks for the tip!

So I now have all the sensors back on and I am getting a ton of codes thrown. And an occasional Misfire and SES light. Also installed a Dual AFR gauge.
