First, thank you for this thread. You really simplified the process and made it much easier to understand.

I have a few questions:

In the DIY it says "For newer build cars after the flash the paddle shifters no longer works...If this is the case you would follow part II of this DIY.." Could you define what constitutes a newer build car? I have a 2008 BMW 335i.

Also, for JB4 tune, you mention putting in "valet mode/map 0" I think map 0 is simply disabling JB4. Do we do this only when flashing or also when first testing the transmission after flash?

A lot of people complained that the Alpina B3 flash is not very good in the "D" mode. Is it severely different from stock mode? In other words, if I had to accelerate fast in "D" mode would there be a serious lag because of the low RPMs or need to downshift?
