If you think the ZF 6HP 26 is good in "standard" BMW guise you should try it with the Alpina programming
Have you got that on your Supersport Ken?
Nope - ZF 6HP 26 was used the in E9x B3 and E6x B5/6 ranges. The shifts are noticably quicker than the standard BMW version. Manual mode is available in both normal and sport mode. In the B5S it defaults to 2nd gear for pulling away - mind you with about 500nm available from tickover its not really surprising.
(I used to have a B3X and have recently tested a B5S)
