How to find the Serial Number on the SCT Livewire Tuner/TS
The Livewire serial number is 13 digits and starts with LW.

The serial number for the Livewire can be found in two places:

  1. The first and easiest place is the UPC sticker on the back of the tuner.
  2. If you no longer have the white UPC sticker on the back of the tuner, the serial number can be found by powering on the programmer using the USB cable or the OBDII cable. Once powered, go to the Dealer/Device Info Menu (question mark/info icon).
