Alpina Firmware Preservation

Alpina firmware and calibration files often get hoarded and replacement control units are way more expensive than their BMW counterparts.

That encouraged us to create this preservation area with some additional information on the different engines and gearboxes.

We will also include WinKFP flash manual if the files are available within SP-Daten.

E36 - Alpina B3 3.0

The E36 325i based Alpina B3 3.0 uses a stroked M50 engine (engine code E3) and a ZF 5HP18 automatic transmission.

Engine Control Unit

We are still looking for a genuine Alpina readout of the Bosch Motronic. Feel free to contact us if you have this file.

Transmission Control Unit

The original Bosch GS7.11 used in the BMW E36 was modified by Alpina to support switchtronic buttons and have faster gear shifts.

The TCU has an AMD AM27C256 memory (DIP-28) that is UV erasable, you can simply write attached file to any other GS7.11 after clearing the memory under UV light.

E46 - Alpina B3 3.3

The E46 based Alpina B3 came in several configurations.

The engine was always based on the S52 engine with an increased stroke to 3.3L (engine code E4) and a ZF 5HP19 automatic transmission.

Engine Control Unit

From March 1999 to June 2000 the early Alpina B3s were equipped with the Siemens MS42 engine control unit and the rest of car was based on a 328i.

Later B3s came with the Siemens MS43 and vehicles were based on a 330i.
