GM Body Control Module tuning for the 2007-2014 Gas/Diesel Trucks and SUV’s
IMPORTANT NOTE: EMAILED EFILIVE BCM TUNING FILES ARE NO LONGER AVAILABLE.
THE BT DIESELWORKS AUTOSYNC AND BCM TUNING ARE FULLY COMPATIBLE WITH EXISTING EFILIVE ENGINE TUNES THAT YOU MIGHT HAVE, HOWEVER WE ARE NO LONGER SENDING EFILIVE BCM TUNE FILES VIA EMAIL.
If you want BCM tuning but do not already own an AutoSync, you can buy both the AutoSync and BCM tuning together in a discount package (select "Do you already own an AutoSync - NO")
NOTE: 2014/2015+ K2xx BCM tuning is temporarily suspended and unavailable. We hope to have new third-party options available soon.
