    • VF-Engineering releases Stage I & II BMW F87 M2 N55B30T0 Hex Tuning ECU flash software showing massive torque gains - Dynojet graphs

      Great news for BMW F87 M2 owners looking for quite a bit more power and torque out of their M2. The chassis of the car is capable of handling much more power than BMW gives it but we all know it can not be allowed to encroach on the mighty M3/M4.


      Well, in comes VF-Engineering to the rescue with Stage I and II Hex Tuning software. Let's start with taking a look at Stage I on a Dynojet in STD and uncorrected plots:




      You see a big torque gain before 3000 rpm and gains throughout the curve which level off toward redline. The N55B30T0 is not exactly a classic M top end design but it sees over 400 lb-ft of torque at the wheels with just the Stage I tune.

      Now let's look at Stage II:




      The Stage II software picks up 52 peak wheel horsepower but the torque gain is a massive 78 lb-ft at the wheels. The peak torque figure is an incredible 442 lb-ft on the Dynojet.

      That is something you are going to feel. I can say that with certainty as I went for a ride in VF-Engineering's Hex Tuned M2 and it is very stout down low. It pushes you into your seat right away.

      Does it pull like a freight train up top? No, but that is the nature of the N55B30T0 engine. The software complements the factory curve and just gives you more of everything including more power in the upper rev range where it is desperately needed.

      The software is not just about power and torque gains but offers additional features such as a limiter delete, throttle overrun (exhaust burble), start up roar, and an increased power level on the Sport Display. It all felt very OEM and worked perfectly.

      You wouldn't want a stock M2 after trying it out, let's put it that way.

      (all on 91 Octane. Average gains over multiple runs.)

      NOTE: We never take the lowest Stock Run, and subtract that from the highest Tuned Run.

        $895 for Stage ONE.
        $995 for Stage TWO.

        Software price includes our HEX Flash Cable which is used for MAP switching activities.
        IE: Updates, Upgrades, switching between Stock and Performance Tuned files.

        That's VERY reasonable.

        Bench Flash?

        All F-series ECU's do need to be removed and unlocked in order to enable port flashing.
        It's a one time process that at this point remains a necessity.
        After the "unlock", everything else happens through OBDII.

        Is there an ecu removal DIY?

        For the F3X cars, not yet.

        We made a quick one for the F8X (which is similar), but wanted to stress that it is still a more advanced DIY.

        Sure.
        Next local customer who comes our way I'll try and get some video of the install.

        Any sounds of the GTS roar?

        I don't have any clips of the "Start-Up Roar", but how about some Throttle Overrun as a consolation prize?!

        Stage ONE - Stock Exhaust


        Stage TWO - Turbo Back (Meisterschaft)

        The throttle overrun is very cool. Very similar to how it sounds on my 911 with PSE.

        Not a bad price. Do you have any authorized dealers/sellers in Europe? I'm looking at M2s soon but live in Italy. Would I have to mail the ECU to the states?

        We have a dealer in the UK, which should be much easier than sending to the US.

        If you have any suggestions for BMW Performance Shops in or around Italy, feel free to drop us a PM and we can look into them for possible Italian dealers!

        Just a heads up, our dealer in the UK can turn around the
        ECU same-day, so there is very little down time if you do
        decide to go that route.

        If you ship it on a Monday,
        they receive it on a Tuesday,
        you get it back by Wednesday!
