My answer was also based on buying it from an Si owner lol. It was converting a '17-18 Si file for the '19 Si ecu.My answer was based on you buying a Ktuner from an Si owner. @arpypat solution works also should you buy it from a non Si owner
@Drake - you may have to contact TSP to see if they can convert a Non-Si TSP stage 1 file to an Si TSP Stage 1 file. They might do it for less than the cost of a whole new file.
