GM TECH2 program out the GM Corvette F45

GM Tech2 clone scanner is tested ok to program out GM Corvette F45.

Steps:

1. Hook up Tech II, turn car on, make sure module in the rear is plugged in. Do not unplug the rear module.
   2. Use Tech 2 to delete the F45 option (F55 does not appear on the menu screen, use F45).
   3. Save new configuration.
   4. Do not turn car off, do not remove Tech 2. Go to the module in the rear of the car, unplug the grey connector (the widest one), leave any other plug(s) in. [leave the other 1 (F45) or 2 (F55) plugged in]
   5. Turn off car, leave Tech 2 plugged in.
   6. Remove remaining plugs from module in the rear of car. [never plug them back in again, if you do the F45 turns on automatically]
   7. Turn car on to verify the “max speed 80 mph” is gone.
   8. Unplug GM Tech 2.
   9. Never plug the connectors back in.
