Hi.  

Is there different types of zusb for 335i alpina flash? 

Been reading that 7615835 is the one to use, but is there any differences between Alpina GT3 and regular Alpina 335i ?

There are 2 different current alpina flash ZB numbers. Reading and decoding the options for each ZB in kmm_ATSH.txt may reveal the difference. 7603537 is the other one.
