Hi, I’ve tuned cars before but now getting in to these German cars but I don’t know how I can do a custom tune myself. I know what to do I just need the software to tune it from my laptop or phone.

I know for ls tuning there is no tuner that connects to my laptop and I can modify it whenever I want, that’s the kind of thing that I want, if anyone knows what tuning software I can use to tune it myself let me know. Thanks.
