Made good power and got all of the little stuff sorted out. Need help with a few codes though. P0100, P0400, P0420, P0430. Any ideas on where to start with these? The reports stuff is quite a bit different than the other modules.
Made good power on C7 Z06.... 684whp and 664TQ light bolt ons

Anyone?
I'm not sure about P0100 and P0400, these might be related to MAF and EGR respectively (does not make sense, the C7 Z06 does not have EGR...?).
P0420 and P0430 are catalyst reduced efficiency, however I heard that there may be a GM TSB regarding these (TSB says to flash a new calibration into ECM), altho I don't think it applies to C7. P0420/P0430 are from running a test that manipulates EQR and measures response time from front O2 to rear O2, if it is too short then the test fails.
I don't follow what you're saying...The reports stuff is quite a bit different than the other modules.
do we have access to the delay settings for the cat test?Originally Posted by joecar
