• 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.

Maybe the more aggressive BS tcu tune creates more heat in the trans with faster harder shifts and more aggressive matched rev downshifts, I am sure the ecu retards timing once the trans temps get way up there and pulls timing to cut power. I am no engineer but I would think faster harder shifts create more energy and that can equal more heat. I am not saying that is the absolute case, but it migt be something to ponder. These cars ECUs are smart and the cars self preservation kicks in and they do all sorts of stuff. Have you had the car on a dyno to back up your claims of less power? I have no issues with you and you're usually pretty well informed on most topics pertaining to M156's and M159's but to come on here and make a blanket statement that the tcu tune does not work when I know people that have the exact same tune and are VERY impressed with you it might be jumping the gun a bit. You and your brother are kind of like me, your always pushing the limits of these cars and you guys are not affraid to take them to the track and use them.
        Jim, I think you dont have the whole picture. Nobody is pulling any gun. The problems was not just the TCU , the problem was/is the ECU. TCU has been flashed back to stock.

        I dynoed it after the tune , and yes it was making less whp than a stock SLS and I sent steve some Vbox runs


        With the previous tune , the car did 60-130 in 7.7-7.9s on a 105F degrees wheather!

        after the upgarde...well lets just say it was nowhere near that

        anyway, we dont want to comment anymore. I did not even know that my brother came in here and posted about this, I did not want to see any of this happening, especially here on the forums

        Steve, is great guy and he is currently helping him in getting the issue resolved just like he usually does with his customers.

        Issue will be resolved for sure bro, everybody will be happy

        Sounds like an isolated case, hope everything works out and I am sure Wesitec will sort out the problem, whatever it might be.

        the issue was not the refund. If that's what Weistec are telling you, then you have no clue!
        @Weistec , please shut this clown up , @SLS AMG already promised not to talk. Why are you discussing our matters with people who have no business or have any clue?

        What are you so upset about ?? You said the car was flashed back to stock, so it would only stand to reason that you (or your brother) got a refund. Why are you dodging the question??

        I don't think Weistec would have any problem with my comments here, but based on what they said earlier, they certainly did take issue with your brothers comments.

        Now I'm a pussy ? You are the one who is refusing to be honest and answer the question - were you and your brother issued a refund or not ?? It's a simple question and the fact that you continue to ignore it speaks volumes about your character.
