Update Your CTS3+ and Flash Custom Tunes

Here's a step-by-step guide to updating your Edge CTS3 + and flashing custom tunes onto your truck.

First, you'll need to get the Update Agent 1.0 software. This software is essential for updating all Edge CTS3 products.

Once the Update Agent is installed, you're ready to update your CTS3.

Open the Update Agent software and create a user account.
Plug your CTS3 device into your PC with the included update cable.
The Update Agent program should auto-detect the CTS3 device and populate your device's serial number and part number.
If the device has required updates, you can select 'yes' to update the device when prompted.
Once the updates have been downloaded into your CTS3, the device will automatically reboot and Update Agent will tell you it is 'Up to Date'.

Now it's time to get your CTS3 ready for tuning in your truck.

Install your device into the truck and when powered up you will select 'Tune' in the menu of the CTS3 device and begin the flash tuning steps.

To use third-party custom tunes, you'll need to generate a backup of your stock file.

Flashing the truck with the 'Modify Stock' will generate the required 'backup.frd' files you’ll need if you’re opting to run third-party Custom Tunes.
Once this process is completed, you can then take your CTS3 back to your PC.
Once connected at the PC, open the CTS3 drive populated and open the 'Tune' folder. Copy and paste the 'backup.frd' file to your desktop.
Email the .frd file to sales@jelibuilt.com email thread.

Once you receive your custom tune files via email, you can load them onto your CTS3.

Once they have generated your custom tune files and emailed them back to you, reconnect your CTS3 to the PC and simply drag and drop your new files onto the main drive of the CTS3 and not any of the folders.
The device will confirm that you loaded each file(s) one by one. Hit continue to confirm each.
Returning to the vehicle with your CTS3, power up the vehicle in the run position, without starting the engine, select 'Tune' and then 'Custom Tuning'. You should see your new Custom calibrations within this sub-menu, which can then be selected and flashed into your PCM.
