Hello.

I have re-wired an E67 run LS3 to now run on an E38 L98 ECM. It all runs fine as in the wiring is correct and validated, it's just not happy idling etc with the unknown L98 tune that is in the E38 currently. All I've done to it is disable some DTCs and VATS for the transplant.

Is there a simple way to migrate the tune for the LS3 from the E67 to the E38?

Cheers
