-What's the process?-
You are purchasing our remote tuning service. After purchasing your tune, you will receive an email with our software download and instructions to begin the tuning process. It is a very straight forward process. You will need a Windows laptop or Android Device and K+DCAN OBD2 Cable.
You'll essentially check for any codes the car may have and save them. Then pull a backup of the ECU as it currently sits and send it in to us. We'll then build your tune, and send it over to you for uploading. It's easy as that!

• Windows 10/11 Laptop/PC Software
• Android Mobile App (CCFlash Mobile on Google Play Store)

For MS45 ECU Tuning, it is HIGHLY RECOMMENDED to use quality cables with updated firmware. Generic cables from ebay and amazon (and similar) with outdated firmware can cause issues when uploading tunes to your ECU. If you are unsure about the cable you might already have, feel free to ask us and we can let you know.
