    • World first - Weistec cracks the SLS Black Series TCU (transmission control unit) and has control of the M159 SLS dual clutch gearbox

      This is serious business right here and continues to show that the grasp Weistec has on the M156/M159 platforms is unrivaled. The SLS Black Series just like the standard Mercedes-Benz SLS AMG features a dual clutch gearbox. However, the redline on the two cars is different as the SLS M159 V8 revs to 7200 rpm and the M159 V8 for the SLS Black Series was redesigned to rev to a higher 8000 rpm redline for more top end horsepower and tighter gearing.


      The dual clutch transmission software of course was also changed in the SLS Black Series to accommodate the higher redline. Not to mention the more aggressive shifting profile for the Black Series. Weistec is able to flash a stock SLS with the Black Series TCU software. This answers a question BenzBoost raised a while ago when the SLS Black Series came out regarding if one could retrofit Black Series parts and software to the standard SLS. It certainly is appearing increasingly more likely that SLS owners will be able to update their cars with the newer AMG parts and software.

      Expect a release with the product information and cost in the coming weeks. Weistec is testing the M159 V8 in the standard SLS to see how it reacts to the increased RPM as far as longevity and durability is concerned before officially releasing this software. The custom Weistec coded TCU software requires an ECU flash to function correctly as well.

        There often isn't any logic to people being negative.
