    • 2015 BMW F80 M3 / F82 M4 S55 inline-6 ecu flash dyno results from Jailbreak Tuning

      Well that was pretty fast. As reported last week the M3 / M4 S55 engine control unit has been cracked. Keep in mind this is very early in the flash tuning process of the new M3 and M4 but there are multiple tuners with the ability to flash the ECU out there with many more to come. Jailbreak Tuning posted the first Dynojet results of their flash tune and the result on 91 octane pump fuel is an increase of 20 peak horsepower at the wheels.

      Obviously peak horsepower does not tell the whole story especially on the newer BMW turbo motors as the gains in the mid-range are in the 50 wheel horsepower range. The torque curve is much fatter and the peak torque figure increases by 42 lb-ft at the wheels.

      People will obviously being comparing these flash figures to the BMS piggyback tune figures. As of today, piggyback tuning shows greater horsepower and torque gains. It will be interesting to see how these two approaches play out and the way they play out will likely be reminiscent of the N54 tuning scene in which each approach has its place with many people using both for the optimum setup.

      Regardless, the flash tuning era of the S55 inline-6 motor is officially underway.

        you guys read that from me lol and yes it is true. remember the whole $#@!storm with Powerchip? Matt went through some issues with Wayne and his bull$#@! lawsuit headaches and then stayed real low key for a while and focused on tuning. then he comes out of nowhere on M5Board, joins as a "guest" vendor (he got banned because the staff demanded he become a sponsor since he was selling tunes for BMWs to the members but "he refused"), and heads straight to the E39 M5 guys.

        he then went and fixed a bunch of people's $#@!ed up PC tunes for free cause he's a stand up guy. then he showed some sexy ass gains for an E46 M3 he tuned and right there started JB tuning. he's tuning a lot of platforms apparently, one guy with an M6 got tuned by Matt and had nothing but good things to say.

        so yeah thats Jailbreak tuning

        i caught on right away when he joined this forum right after the rumors of the S55 ecu was cracked. i nailed it.

        so even you have $#@! on him?

        damn, i had no idea it was actually a global issue with him. that just makes it all the better how he gets treated. Don't think anything can top the gearboxing though.

        I think it's bench flash as it's a Bosch MEVD172.G (Infineon Tricore). Kinda the same as in the N55. This has a G in the end which I have NO idea of what it should be.

        If you bring Motec enough interest they can easily provide a plug and play stand alone engine management system for the 2015 M3/M4 like they already for the GTR and BRZ.

        http://www.motec.com/nissangtr/nissangtroverview/

        Their experience with BMW is extensive and are the first to have a stand alone ECU for direct injection

        http://www.motec.com/latestnews/news-bmw/

        http://www.motec.com/latestnews/britcar24hourwin/

        It is high dollar but the confidence one can have by the exacting control of all engine parameters allows one to shoot for much higher HP levels not possible with any future flashes to the OEM ECU

        You can even add secondary port injection running additional (to direct cylinder injection) 2,000 cc injectors, with the right bottom end the sky is the limit

        I sell tunes, simply some random guy sends me a stock file of whatever car (VW golf 2.0 tdi or even 997.2 turbo S), me and my buddy make whatever stage 1 2 3 desired and send it back. We know most of the tuning companies, not all do their tunes themselves Click here to enlarge PM me if you like any info!

        When I read about the GTR M1 plug in solution, I missed the word essential, glad you straightened me out

        No problem. If we could just plug a Motec in and keep everything working like OEM I mean... that would be ideal.
