110C3 Selected Custom Tune Is Not Compatible With Vehicle.

    December 17th, 2021

    Things to check:

    • Check to see if the device is in Demo Mode: From the main menu go to "Device Settings".  Scroll to the bottom and you will see Demo mode, make sure it says disabled, or off.
    • Make sure if using a custom tune, that it is written for the correct ECU strategy of your vehicle. To check your vehicle's ECU strategy: Select “VEHICLE INFO” then Select “Continue”  displaying your VIN, COMM, and ECU Strategy.  If the strategies don't match, you will need to get a tune that matches your vehicle's strategy.
    • Check to see if there is an update available on the Device Updater.
    • Steps to update:
      • Make sure you have the Device Updater Software installed on your Windows PC. If you do not have it please click here 
      • After downloading and installing our Updater Software open the program. There should be an icon on your desktop.
      • Once Updater is open on your desktop. Plugin your device. 
      • With the device plugged in select Automatically Check for Updates from the Basic Operations menu.
      • Your device should start to Update. Notice the bottom bar it will let you know what part of the update it’s on.  This can take some time so be patient.  Your internet connection and computer speed can impact updating times.  The average time is 5-10 minutes but can take hours if the device hasn't been updated in a long time. 
      • You know you are done when SCT Device Updater displays "Device is up to date!

    If your device is up to date and is on a supported vehicle, loading a "Stock" custom tune to the vehicle will correct this issue.  A stock custom tune is just your vehicle's stock tune made into a custom tune with no changes.  Once that is complete you will be able to tune as normal without this error.
