    2017 Camaro Procharged codes

    I have a 2017 Camaro A8 with a Procharger on it. It makes good power and drives nice however there are permanent codes, P0121, P1400, P2097 P2099, showing up with Diagnostics in HP Tuners. The MIL Light is not displaying on the dash. The rear O2 are swinging from 0v to 900mv and the trims are fine on the front sensors so am not sure why it is throwing P2097 & 99 Post catalyst fuel trim system high limit bank 1 & 2. Thoughts on what these codes could be from.

    Thanks Sultan
    The balance on the trims seems OK. What would you suggest to sort it out.
    This car has 2000km on it with the only modification the addition of the ProCharger.

    Switch of your LTFTs and fine tune your MAF to get your STFTs inline. The LTFTs learn too quickly on the D.I. motors and cause this code a lot.

    These Permanent codes cannot be cleared. They need to be avoided by having the software / ECM setup before the mods are made to prevent them. Once set, you have some insane number of drive cycles to hit (after setting up the software properly) before they bugger off. They don't set the light and you can't see them with older scan tools, but newer ones can. Permanent codes are an '09-later thing designed to make it harder to "emissions cheat" by unhooking the battery to clear trouble codes. If you block them from ever being set, you are good. If they set, set them up properly and eventually they will clear. They will be suuuuuuper slow, but they will go away.
