On a limited number of BMWs, for example the BMW E9x 335i and 335d, the BMW transmission software can be replaced by an Alpina version. The effect of this is that the car drives a lot more comfortably in D. The car becomes considerably less nervous. In addition, you can see not only in Sport (S) which gear you are driving in, but also in D (D1, D2, D3, etc.). Furthermore, the car shifts faster and the engine automatically receives a dash of throttle when shifting back (throttle-blip) to make switching back more smoothly.
Unfortunately, since xHP is available, the tunes from Alpina have become quite obsolete. For that reason we strongly recommend not to go for an Alpina flash, but to opt for xHP immediately. Click here for more information about xHP
