2019 TSP tune w a 2020?

[genxcoupe]

Hi everyone I found a used ktuner I am going to buy with tsp stage 1 and 2 already loaded. I have a 2020 si and the owner of the ktuner had a 2019 si. Will the tsp tunes work with my car?

Are tunes locked to the original CPU? If it works the final drive ratio is different, not sure how that would affect anything.

Idk I don’t think so. I know the 2020 has different tuning then the 19 oem, however TSP says the stage one tune will work with any si 17-20.

Sorry, the files are not cross compatible due to different ECU software versions.
