Tuning the swapped 2010 Cadillac CTS 3.0 LF1 engine with 2012 Cadillac CTS 3.6 LFX

[khalid13]

I Swapped my 2010 Cadillac CTS 3.0 LF1 with the 2012 Cadillac CTS 3.6 LFX engine. Car is working but I cannot install the 3.6 stock tune on the vehicle, therefore, the car is not tuned properly.

I need support in this please.

Can you swap out the ECU? Not sure these can be remapped yet easily so a piggy back or replacement ECU are other options if you can't do an ECU swap.

Warning, often swapping the ECU will change the immobiliser and you'll need to switch out the locks and ignition systems as well.
