Failing emissions (readiness checks) after a cam install. Can anyone help? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I put a new cam in my car about 2 years ago, and got the car tuned by a great tuner, well respected on this board. At the end of last season, I failed emissions due to failing a bunch of readiness checks.

I emailed the tuner I used, but haven't heard back yet after a few days. I really need to get the readiness checks passing. If anyone can offer me any help or direction, I would greatly appreciate it. I am including an image of my readiness screen in HP Tuners. I cannot seem to include my log of tune, but will gladly email it.

The car is a 2010 Camaro SS, L99 with a big VVT cam in it.

Delete all the 02 heater codes in the tune. That will fix it.

Yup, set any codes related to those readiness tests to "3 - No Error Reported" and they will go to complete automatically.

Thanks, I will try to do that tonight, the weather has been pretty crappy here, so I may not be able to put any miles on it.

Is it pretty apparent what codes tie to these systems when I look?

Thanks again

I just looked through the tune, and anything that is Exhaust Gas Re-circulation related is already set to 3-No Error Reported.

This one is especially weird to me, since I didn't think the L99 had EGR even.

I also looked at the O2 heaters and it looks like all the heater codes are disabled for bank 2 already.
