Dealer update! A hig

Dealer update! A highly anticipated update for Bavarian motor specialists! We are proud to announce that the ZF 6HP Transmission Control Unit (TCU) is now fully supported through the diagnostic port on your AutoTuner Tool.

This legendary automatic gearbox equipped the vast majority of BMW (and Alpina) models throughout the 2000s and early 2010s. Tuning this TCU is an absolutely crucial step to unlock the full potential of tuned engines, especially on the highly popular N54, N55, and M57/N57 diesel blocks where torque is often limited by the stock transmission software.

⚡ Method: 100% OBD (Normal Read – NR) Forget about lifts and tedious under-car access. Plug your tool into the OBD port, read, and write directly from the driver’s seat. Absolute workflow comfort!

Supported Highlights:
– BMW 1 to 7 Series: E8x, E9x, E6x, E65… (18d to 40d, 20i to 50i, 35i N54/N55 engines)
– BMW X & Z Series: X1, X3, X5, X5M, X6, X6M, Z4
– Alpina: B3, B3 S, B5, B6 S, B7 (35i N54 & 4.4 V8 bi-turbo engines)

Provide your customers with faster shift times and raised torque limiters on these iconic models!
