    • Not so fast with 992 tuning - Porsche rumored to be using Bosch MG1 ECU on the new 911

      This is not confirmed information but it was sent to PorscheBoost by a trusted source. Many of you know the B9 Audi S4, S5, RS4, and RS5 models with the Bosch MG1 engine control unit have yet to be cracked and tuners are struggling to do so.


      It seems Porsche is borrowing from their Audi sibling for the 992 generation of the 911 and employing the same ECU and encryption. Tuners are stymied and do not even know where to begin.

      What does this mean? It means the 991.2 is the model to have if you like to tune. It also means piggybacks will likely dominate the market for some time.

      Remember, even the 991.2 ECU took a while to crack and still requires a physical unlock. Porsche is becoming and more and more successful at keeping tuners out as are most OEM's.

      The good news is Bosch MG1 applications for the 2.0 Audi/VW motors have been cracked so there is light at the end of the tunnel.

      No doubt the ECU will get cracked but the question is, when? And when that happens, will anyone care or will they be on to the next generation?

        Isnít the MG1 used in BMW applications that can currently be programmed?

        I believe so. I'm not sure what changes Audi made so that the B9 V6's can't be modified at least not yet.

        I’d imagine its the encryption used and not the actual DME. Perhaps this is a hasty generalization? It will be interesting to see.

        I e-mailed a certain someone for greater detail on whether it is hardware or software keeping us out.

        I'll update as soon as I can.

        By who? APR has been trying to crack the Audi for over a year and a half. Now the 2019 GTI uses it too.

        Contrary to what I read on another forum over the weekend, it appears the 2019 GTI does not use the Bosch MG1.

        @Arin@APR just stated it is a Continental ECU for the B9 2.0's (I assume the GTI as well) so that is why they are able to flash it.

        992 is MG1. Good luck everyone!

        It's good for BMS. Absolutely should jump on the 992 bandwagon ASAP.

        Which was exactly my thinking with the 991.2 Click here to enlarge

        MG1 in BMW is cracked. Thats not to say the encryption in the 992 will not be as robust as B9 Audi S4.

        If not more so. Interesting Porsche made the switch that fast from 991.2 to 992.
