Just got my jb4 on my 2015 535 and I don't know how to change maps via the steering wheel. Any advice would be appreciated.

I know map 3 is meth ...5 is auto tune.... And 7 is meth and e85.... I wanted to know more or find out where I could learn more details on each map setting.

I have not got to run my meth kit yet. I put e85 in 10g/6g ratio and could not feel any difference on map5.

Also looking to find out all the other details on the other maps like what happens on the meth map when it runs out or the e85 map etc.

Thanks a lot in advance for the information.

So far the car feels quick with just the jb4 and intake but still soft on the top end. I came from a 07 m6 convertible which was very heavy but it still pulled way harder than my car with the jb4 and e85 ...intake on map5.

Hoping with meth and a different map its a big difference.??

Surprised you didn't go for a 550 coming from an M6

Almost did but was going for mpg and saw a lot of performance potential in the 535 and not as much initially in the 550. Hoping I can extract a bit more out of this guy.
