No, on the TTA's, to kill the power to the ECM for a chip change, you have to do the following:
- Completely air down the passenger rear tire to reset the ECM geo-stabilization system.
- Turn the left turn signal on to divert battery power to the driver's side of the vehicle, dissapating any stored energy in the right (ECM) side of the vehicle.
- Honk the horn twice - pause for 2 seconds - honk three times - pause for 2 seconds - honk once to progam the ECM that the engine size is 2-3-1 aka 231ci.
