    • MHD F-Series N55 tuning update with support for XDI upgraded HPFP's (High Pressure Fuel Pumps]

      This is a great update from MHD adding what is a major development in tuning support for the Xtreme-DI N55 upgraded HPFP pumps. Previously, TTFS (Tuning Tech Frank Smith) was pretty much the only source for N55 tuning with the XDI HPFP.


      The update of course does more than just support tuning for upgraded pumps:

      Added on N55 an xHP setting (transmission choice page) for OTS maps.

      -Added on N55 a linear throttle (flash option).
      -XDI pumps support (flash option).
      -N55 EWG maps v1.08: fixed boost target drops when rail pressure is changing.
      -Added some default min/max values for common log channels.
      -Minor bugfixes.
      A great update for the N55 in particular with OTS maps for XHP flashed ZF8HP cars and updated EWG maps.

      MHD just continues to improve.

        You’re way too much of a bootmod3 fanboy.

        Competition and alternatives are good.

        Plus I don’t remember XDI support on bm3 a year ago. Is there even built in support now?

        Yep proud to be a fanboy of the truth.

        You can see it on their instagram, maximumpsi instagram too dyno'ing my friends car late last year with XDI pump on OTS map.

        MHD was only supporting XDI via Custom Tunes last year (since i know a guy in Germany who got the pump), but Bootmod3 offered full support via OTS and Custom Tunes.

        Give CREDIT where CREDIT is due.

        I'm supposed to give BM3 credit on an MHD announcement?

        Maybe keep the announcement on topic?

        Ok I had no idea BM3 had OTS XDI N55 tunes. I thought TTFS stated they needed to provide their software for it to work.

        Hurray for the software choice you run Click here to enlarge

        Hmm, great for MHD! BM3 has global xdi support now iirc so you click the box and every map will have proper fuel table scaling to run the xdi properly, which is very nice.


        I'd love to get bm3 since I'm they have a very good looking interface, and have really good ots maps. But since im an enthusiast that doesn't mind getting custom tubing done mhd atm is superior as it has one touch support for precision racewerks coils, up coming: map switching on the fly, flex fuel, etc. I have to stick with mhd.

        But it's the tuning game anything can change maybe ecutek (racerom), bm3 or mhd will come up with something crazy soon that'll bring them to the top. Either way I'm not biased, just looking forward to seeing tuning progression for our platform.
