Yea delete the rear 02 codes, pretty typical after cat delete...

Be careful tuning this new ECU...

Hi guys,

I'm having similar problems.

I'm just done tuning a 2016 Camaro with 8 speed auto transmission and everything went fine. Car has gotten new headers, race cats, exhaust and larger air filter.

When we received it it had some O2-related DTC's as well as these:

0x7E8: P069E - Fuel Pump Control Module Requested MIL Illumination (SES, Pending, Current, History) - I can control this through VCM Editor diagnostics, but don't want to remove DTC until I know 100% what it is.
0x7EB: P12E7 (Pending, Current, Permanant) - can't find in VCM Editor
0x7EB: P12EC (Pending, Current, Permanant) - can't find in VCM Editor
0x7EB: P12F4 (Pending, Current, Permanant) - can't find in VCM Editor
0x7EB: P12F9 (Pending, Current, Permanant) - can't find in VCM Editor

Does anyone have more info about this?

PS!

Is "permanAnt" even a real word (should be "permanEnt"?)

Did you happen to delete the AFM valves as well?
