I’m a techy and a tinkerer. I run Linux on a lot of machines and I self host some stuff, and I also mod and tune my car.
I keep a windows laptop on hand that at this point I literally only use for tuning software. If something goes wrong with the car I don’t want to go through trying to fuck with booting a niche engine tune program in Wine on a Linux machine with an OS that may or may not even recognize the OBD device needed to flash the tune. Too many places for things to go wrong and the end result is a car I can’t drive.
Unless you’re very comfortable with having your car unusable for long periods of time while you troubleshoot things, I’d highly recommend having a windows laptop for car tuning.
