To use a newly updated mod-file db when your OFT has already been installed onto your car:

  1. Successfully load a new Mod-File DB to your OFT.
  2. Select Upload Data tab in the left menu pane
  3. Press the red X next to any tune files loaded in the mod-file slots 
  4. Confirm that you would like to delete them.

Disconnect the OFT from the PC, go to the vehicle.

  1. Select TUNING 
  2. Select WRITE. 

Tune files should auto-generate from your new mod-file database if your calibration code matches a known OEM ECU tune in the DB.
