Problem: You need to change the VIN within a Custom OS file. As the Serial and VIN are embedded within the Custom OS the firmware they cannot be changed using the normal methods and the Custom OS file must be be recreated.

Solution: We create a new stock file and re-run the Custom OS Wizard via the following steps:

The guide assumes your previous Custom OS file has been named as "Previous Custom OS.tec"

Press Calibration Tools -> Create Stock File/Calibration Merge

Select "Create Stock File From Existing File" then load your previous custom OS tec file with the old/wrong VIN.

Press "Save/Open File" and save the file as "New Stock File.tec"

If you wish to change the VIN you must do it now via locating Navigator -> Strategy -> Vehicle Identification Number and entering the new VIN.

Save the file as "Stock OS with values copied and new VIN.tec"

Step 2: Create the Custom OS

Select "Calibration Tools" -> "Custom OS Configuration Wizard"

The wizard will now replicate your previous file. Review these settings to make sure they are what you expect.

Press Next and review the next page (depending on what type of custom OS you created you may not see all of these page or options).

If you are recreating a Flex/Multi Tune you will now see the table selection page. The tune and table setup should match the previous Custom OS. Review the table/scalar setup to ensure it matches what you had previously.

Press "Check License and Proceed" and save the new file as "Custom OS re-created with stock values.tec"

Press Next and exit the Custom OS Wizard. Now press Compare/History -> Load Compare File and load the previous Custom OS File. "Previous Custom OS.tec" This is the same process and steps as you did earlier in the guide and will copy over the flex/multi tune tables.

Once again click anywhere within the compare tree view, press Ctrl + A then space to select all of the previous Custom OS tables/scalars. Finally press Apply to copy them over.

Flash the file into the vehicle.
