ECU Tuning - A few questions, and need some direction please

[polar993]

I am considering a tune for my 2017 Alpina B6 GC. I have read a number of posts on various tunes, including BootMod3 flash tune, and custom tunes by reputable companies like Mission Performance, etc. Even after reading through many posts, I still have a few questions that I am hoping you guys can answer for me.

- Will a tune of any type affect and void my factory warranty? My current warranty doesn’t run out for another 2 years.
- Can the car be reset to the original factory settings if necessary?
- Is it necessary to get a fully custom tune, or will a standard map like BM3 be okay?
- Do I need to bring my car in-person to have this done, or can I buy a cable and download some software and do this myself?
- Roughly how much does a tune cost?

The things I am looking to achieve with a tune are the following. My only mods so far are Eisenmann Race Rear Mufflers. Everything else is stock.

- Improve acceleration and overall power
- Improve sound of muffler (wanting more of a raspy sound….but not a ridiculous burble tune)
- Improve shift points….my car tends to upshift way too much. Cruising at 45mph in Sport Mode has the car in 7th gear, which I hate!

My main concern is the warranty. I don’t want to lose my warranty or run into any issues if I need to take my car to BMW for service.


Thanks so much in advance!
