I have a 2004 Cadillac CTS 3.2L. I'm pretty stupid when it comes to gas motors since I've only tuned the Duramax. When I plug in EFILive to this car it works on the E38 ECM setting as far as scanning. Is this the correct ECM for this vehicle? Even some of the DVT functionality works. I just didn't see any support for this year ECM.

Thanks!
