Probably a dumb question

[Sweet6]

When changing the chip is the only way to do it by disconnecting the battery? Or is there an ECM wire to disconnect like the GNs?

I did a search and found my answer.

Thanks

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.

I thought you had to deturboize the turbo first or is that only on GN's ?

Is that word for word out of the supplement manual? :wink:
