change settings without performance tune '06 Vette

How would I just change the CAGS and fan on settings without installing the performance tune? I want to go back to factory tune, but keep the CAGS off and lower fan settings. Also, when it says to turn off key, should I turn off the accessory mode on my '06 Corvette? U7194 predator. I assume I restore the factory tune then start over after it's done to change the parameters. Do I select Factory HP tune and then just go to the parameters?

Appreciate the help! Car is running too lean at this elevation and the COT is dumping gas into the cats to cool them making it run rich--and stink! when I get on it.

you can use the modify stock tune option to do this.

OFF is OFF, not ACC

Thank you for the help.

There was no option on the unit to "restore factory tune." I choose 'modify tune' and reset all parameters. Did this restore the Vette to the factory tune? Thanx

no...thats not restoring it. thats modifying the stock tune, not unlocking the tool.
