    • BMW F-Series OBD-II port ECU flashing finally cracked - No more physical Siemens ECU unlocking necessary for F80 M3/F82 M4, F87 M2, F10 M5, F13 M6, etc

      Tuners have flashed F-Series BMW models for some time now but they would require physical access to the ECU. That means you would have to remove your engine management computer and get it to the tuner somehow.


      After they unlocked it, you could flash it. Well, no more. The F-Series is officially cracked with OBD-II tuning.

      This means you can expect hand held flashing systems to come to market shortly. BimmerBoost will be detailing some of these systems in a subsequent article. Several tuners have contacted this site already on this topic:

      We are about to launch a new chiptuning product for the latest versions of the BMW Fxx series that will undoubtedly be of major interest to your subscribers.
      Expect this to spread like wildfire.

      For those keeping score, the Infineon F-Series ECU's were first unlocked in December of 2014. It took three years to go from there to OBD-II port flashing.

        Ehh to be honest the R8 that I wanted was in NC and it's not easy or cheap to get that finalized and shipped here. I just found a great deal on the M4 and I honestly couldn't pass it up. 2015 M4 6MT in Silverstone metallic. It will be for more development and new parts for the market Click here to enlarge

        Man this is a great time to own an F series car!
        Hope that brings more tuners to the game and more tables being discovered, and not to mention more features being developed.

        Man am I excited! It'll help me save a few bucks in having the ecu unlocked lol!

        I wonder if MHD or bootmod3 can incorporate this technology some how. Otherwise Im pretty excited to see how this all plays out.

        It's going to be a mad rush. There are going to be many options... Even the BB software.

        Awesome! I did a quick google search and it seems mission performance are the ones developing this tech, are they going to keep it for themselves or are they going to share?

        All I really want is a simple flashing solution without and ecu unlock lol. I wonder what this means for piggy backs?

        f30?

        Most likely, it should be all F series and the m2 is an n55 so most likely the f30 (n55) will get it too. Not sure about the N20 or B series motors though. Probably not B series because it's a newer and different ecu.

        You're correct. No B series yet.
