‘19 Q50 RS400 AWD
I have a q50 that was dyno tuned at AMS a bit over a year ago. They used ecutek, and gave me a bin file of the stock tune. Now I’m looking to sell the car as my drive has gotten longer and I want to get into something more efficient and comfortable and something I don’t care about parking in the street. I plan on a selling it to either vroom or carvana they both want it stock tune, but mods are ok. So I have the app and the file, not sure how to revert the tune to stock, anyone have experience with this?
