    • BMW F22 M240i 8AT stock, MHD Stage 1 93 octane, and MHD Stage 2 93 octane dyno results

      MHD's B58 release for F-Series and G-Series BMW's is showing some great results. MHD provided dyno results on a Dynojet rom this BMW F22 M240i stock, on 93 octane pump gas with their Stage 1, and with their Stage 2 tune also on 93 octane pump gas.


      Now, @martial@mhd did not share the stock graph but the car put down 314 wheel horsepower.

      This is with the Stage 1 MHD OTS flash:


      Stage 2 MHD 93 octane, 98 RON OTS flash:


      The correction factor was not provided but the Stage 2 tune is still impressively adding over horsepower a the wheels with a great looking curve.

      Stock M240i 8AT
      93 oct / 98 ron pump gas
      Stock - 314WHP
      ST1 93 - 383WHP (+~70WHP)

        I'm more interested in the torque. Looks pretty nice, 70 more torques between 91 and 93. Those M240is are pretty beastly when tuned up.

        Well both curves are very nice and a function of each other. Finally we have some decent looking factory BMW turbo curves giving tuners something to work with.

        Seems pretty real world rather than drag strip special, so very applicable.
