adding genuine z4 add ons

[IAmOrion]

However unlike the sport button, the sprint boost remembers the previous setting and stays on next time you start the car. Wish this was a feature of the standard sport button. First thing I do every time I drive the zed is hit the sport button.

Just so you know - due to popular demand (mainly by people inboxing me after seeing some of my other projects) - I will soon be selling a plug and play module that can a) Activate sports mode straight away, button works as normal b) force sports mode (if desired), but works, but turning off sports mode via button will simply result in my module turning it back on c) remember state - my module will remember if sports mode was on or off and then either turn it back on next time or not, as the case may be

I posted on FB, but not got around to making a forum post yet, was finalising some code and pcb details before I make the post
