Kia Sportage QL / QLE 2.0 CRDi (2015-2021) automatic gearbox (6 speed) tuning  via OBD2 port with official instructions of usage. I have used it twice in 3 years (had to reflash it after a Kia official update on the car). Works as intended and described. No wear & tear marks. Sokd as it's not compatible with my new car
