Pretty straight forward. Plug in the tuner and your laptop. It’ll lock the tuner to the ecu, it’ll download and save the factory tune to the ktuner unit, you select the file Phearable send you and load it straight to the ecu. Takes a few minutes and you’re good.[
so because of this , I bit the bullet and ordered it! Never delt with a Ktuner , so I’ll need to read up , how to add the tune when it comes in and how to navigate it.
