Programming Procedure (GMT-900)
How is CCE custom programming installed?
All CCE custom programming is distributed over-the-air via the third-party AutoSync tool, available from BT DieselWorks.
You must already own an AutoSync before purchasing any programming!
We do NOT do "mail-in" programming services or vehicle module exchanges.
We are NOT able to setup new replacement modules. If your BCM, radio, etc has failed and needs to be replaced, you must have the initial installation and factory programming done at a GM dealership before installing aftermarket custom programming from us.
Once you have purchased programming from us, your vehicle's module license should be activated within 24-48 hours. You are free to make tuning/customization changes at any time, even before the license shows "Ready", however the AutoSync will not actually be able to download the custom programming from the cloud until the license shows "Ready".
When the custom programming is licensed and ready for download by the AutoSync, it will show "Licensed - Ready" on your AutoSync profile/vehicle manager. If the module is showing "Licensed - Not Ready", that means that there are additional setup procedures that we must complete 'behind the scenes'.
If the license status does not change to "Ready" within 48 hours, please contact us
Once the module license shows "Ready" and you have made all of your desired tuning changes/settings, run the WiFi firmware update on your AutoSync device. This will fetch your new custom programming from the cloud. Once the AutoSync download has completed, you must then download the programming from the AutoSync into your vehicle.

(vehicle must have manual tap-shift buttons on the shifter, vehicles with the 4-speed automatic transmission are currently not supported)
With the ignition ON, engine OFF, open up the AutoSync main menu, and go to Page 4. Then go to "Module Programming". You will see all of your available/licensed modules listed. You will only see modules listed of which you have purchased licenses for. If you have purchased a license for a module and do not see it listed,
- Be sure that you have done the AutoSync firmware update so that your most recent/updated tune settings are downloaded to the AutoSync
- Plug the AutoSync into the vehicle
- Turn the ignition ON, engine OFF, wait 10 seconds.
- Be sure that the cruise control on/off switch is ON (orange LED on the cruise control switch is illuminated)
- Press and hold the cruise RES+ button and the "+" button on the shifter together simultaneously for a second or two until you hear a chime and see the AutoSync main menu appear in the Driver Info Center. Release the cruise control/tapshift buttons.
- Use the tapshift +/- buttons to scroll through the AutoSync main menu
- Scroll to the "MODULE PROGRAMMING" menu. Press the cruise RES+ button to enter the module programming menu.
- Scroll to the module that you wish to program (BCM, IPC, radio, etc)
- If the module that you wish to flash shows "NOT AUTHORIZED" even though you have already purchased a license, please try the AutoSync firmware download again, and verify that the module license shows "Ready" on your AutoSync online web account portal.
- Press the cruise SET- button to flash the "MOD" (modified) tune. Press the cruise RES+ button to flash the "STOCK" tune.
- The module flash procedure will show status/progress in the Driver Info Center, and should take less than 30 seconds.
- Once the flash is complete, turn the ignition OFF and wait 10 seconds.
