• What an M156 (63 AMG) ECU/computer ruined by a tuner looks like and how to fix it

      We are not going to name any names here but chances are there are a few M156 ECU's out there that look exactly like what you see here. This ECU was drenched in epoxy gunk which essentially ruined it without the owner knowing or providing consent for the ECU to be modified in this manner. The only way to remove the material to be able to tune the ECU was to use a CNC machine carefully to remove it over a period of a couple hours. It was a coin flip whether the board would be hit essentially creating an expensive paperweight but the ECU was able to be salvaged and tuned as the material was removed without hitting/damaging the board. Make sure you do not have to go through this ordeal with your ECU and be careful what tuner you go with.

        Yes. Although Techtec probably does not know they have other options for US distribution.

        You tend to take things the wrong way frequently, I don't know why. Techtec will come to the USA, that is not a shot at anyone simply what is happening that will affect tuning options.

        I'm sure you would like to be able to have the option of their tune directly.

        Quit being an ass. It was a legitimate question and I was looking for confirmation one way or the other.
        Seems you're the one who won't give up and continues to chum the waters with backhanded comments like the above.
        We've moved on - why can't you ?

        Nobody moved on. @BAD430BENZ was right. If y'all moved on, then MHP wouldn't have been mentioned. Just sayin that's what he was referring to and he wasn't the only one thinking it.

        I'm out for the night. Gotta take advantage of the pumpkin ale while it's available.

        This thread is ABOUT MHP. I'm sorry, would you prefer I take it off topic and discuss something totally unrelated ?? Jesus, some people just love to $#@! about everything. My question was valid considering the context here. I'm actually interested in a Techtec tune as it obviously yields good results however I would never buy it from MHP especially after their markup.

        Because the member posting for MHP is banned apparently.

        Let's say we are not friends.

        Half the time I get the impression this thread is very personal to you, you respond to every opinion given here.
        And on top of that you are the most judgemental person in this whole thread.
        Please do not verdict other peoples lifestyle Luke. For once, use the force, and stay away from the dark side.

        Just temporarily, I'm not sure how else it needs to be said MHP can post for themselves if they feel the need.

        This thread really isn't about MHP as much as people want it to be. It's about an ECU issue and a valid one.

        Nope, don't understand because as stated this was never an issue before. I didn't even know Jbond was Andy at first as I was surprised to learn about it as well which he thought was funny. It wasn't funny and I didn't condone it. That is why eventually I had no choice but to simply expose it. That isn't driving the getaway car, that is turning myself in. Why would I expose it knowing I would take some blame unless I was prepared to take my share? I said I was sorry I did not do something about it earlier but I did do something about it. Sorry I did not do the right thing earlier, that is my mistake. I'm still not the one who abused the accounts, he did.
        Understood.

        It's all good, no hard feelings I hope?

        Anyway, it felt good racing again last night, it's been a couple of months.

        I went to Atco but the track prep was terrible. Couldn't hook up even with drag radials. Decided on my last run to put traction control in sport mode and managed an 11.70 @ 122.56 with a mediocre 1.837 60'

        Made a total of 4 runs:

        Run 1: 12.25 @ 119+ (1.988 60') Traction OFF
        Run 2: 11.90 @ 120+ (1.918 60') Traction OFF
        Run 3: 11.84 @ 121+ (1.914 60') Traction OFF
        Run 4: 11.70 @ 122+ (1.837 60') Sport mode

        The car was getting stronger with more runs coupled with cooler weather.
