Edge Insight CTS3 Custom Tuning Setup

This process outlines the required steps to setup your Edge Insight CTS3

Visit edgeproducts.com and select ‘Support’ on the homepage header menu.
Select Software Updates and download the Update Agent 1.0 software which is available
for both PC and Mac users. This software is used to update all our CTS3 branded
products.
Once the Update Agent software has been downloaded and installed, open the software and
create a user account. Once the user account has been created plug the CTS3
device into the PC with the included update cable.
Update Agent program should auto-detect the CTS3 device and populate your
devices 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’.
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, starting with the ECM/TCM
unlocks. The device will walk you through these steps, one-by-one. There will also
be unlock instructions included with the hardware you received to help with that
process.
Once the vehicles modules are unlocked, you can reconnect the CTS3 device
directly to the OBD-II port, you’ll no longer need the Unlock Hardware for any
flashing in the future.
Flashing the truck with the ‘Modify Stock’ will generate the
required ‘backup.grd’ 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.grd’ file(s) to your desktop. These files can
then be emailed to your preferred third-party calibration company. Our email is stockfile@duramaxtuner.com
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 ECM/TCM
