P0602 won't go away after stock tune

[tmd07]

I have a 2001 Mustang GT that I recently purchased. Has some mods and came programmed with a Diablosport Predator programmer which I have. I had the codes P0602, P0605, P1211, P1690, P1000. I know the P1000 is from me disconnecting the battery and I need to drive the car to get it to clear. I put the stock tune back in today in preparation for the Massachusetts OBDII inspection testing. I still have the P0602 & P1000 codes. Will both of these clear on their own? I cannot start the car right now because I have the exhaust off and some other small things I'm working on. The stock tune went in with no problems but I am concerned about the P0602 code. Today I also updated the CROM file to 9r09. I did try to clear the codes as well with no luck. Is there another option I can try with the programmer? I eventually will probably upgrade to the newer style tuner, but right now I just need the car to be OBDII ready. Can a dealer reflash my computer for the P0602? I understand that the P1000 is a "not ready" code and will eventually clear itself. Thanks for any help.

P0602 is part of the KAM or keep alive memory. Pretty much the same as P1000.

OK so does that mean it will clear like the P1000? I also noticed that when I connected the Predator to the computer and power supply that the "original backup" is still listed in the tune list. I verified with the Predator that the last tune written was the "original backup". Does that always stay in the Predator now? If I decide to sell it or turn it in for an upgrade is there a way to clear that original tune and restore it to "factory settings" Thanks.

If it says the last tune written is the original backup then you're good and it's reset.

Update. I installed a factory h-pipe setup and tried running the car in stock tune. It ran and idled great but once the engine warmed up and the idle kicked down it wouldn't stay running. I installed a modified stock tune with adjustments to the idle and gear ratio and now it stays running. I also noticed that once I installed the modified stock tune the P0602 went away. The only code I have now is the P1000 readiness code!
