    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.

    Very new to the N54 engine and have been considering options for tuning. Wondering if someone can clarify the capability of bimmerboost flash for me. Can you use OTS maps (such as shivs)? Are there any other OTS maps available that are ready to go? I have been looking for awhile but unable to find such simple info. Thanks In Advance!!

    Hi friends hope anybody out there, who can help me to fix my selfmade COBB map?! I do actaully face, huge problems with the wgdc after spool, in the low rpm (3000-4200). It jumps from 30% to 50% back and forth. I made over 100 logs, to try to fix this problem, but unfortunately the result is not that good and im runing out of idea. Is there any easy way to calm down this WGDC oscillations? What i did up to now, is try to fix it by the WGDC (base) and playing around with the WGDC ceiling. My actual mod is N55 COBB with stg1 turbo upgrade. Is it possible that you can give me a hint, how i could solve this problem? It would be very great.... Im really lost. The car is going very well once im on rpm, also on the track i have no issues. Im reaching actually up to 19psi at 5300 rpm (post shift DCT). These are my actual logs http://www.datazap.me/u/anatomius/stg3-sport-v154?log=0&data=3-4-16 many thanks

    musc replied to a thread BimmerBoost Flash questions in N54
    Yes. The E85 backend flash runs a lot more timing than stock and a more aggressive fuel scalar to account for the Ethanol. You need adequate amounts of Ethanol to run the E85 flash as well, generally E50+. If you switched back to a tank of pump gas with the flash you will be running too much timing and a scalar not suited for pump fuel. If you tend to run E85 just occasionally (and not excessive amounts, such as in a few gallons in a full tank of 91/93) then you'd probably be better off running the pump flash and just running Map 5 when you add the few gallons of E85 to make more boost. Not sure what Map you are running now.

    Correct, but see it like we see people cross shopping gtr's and corvettes or M3's and corvettes. On one hand you have rear space for kids, trunk space for whatever, on the other hand a 2 seat sports car. Same price range 2 different styles of driving.

    You probably need some ASAM based diagnostic tooling for the tcu platform. http://de.wikipedia.org/wiki/Association_for_Standardization_of_Automation_and_Measuring_Systems http://www.asam.net/ (Good page) (Siemens mentioned on FrontPage) https://www.dspace.com/en/pub/home/company/standards/asam.cfm But somebody above was right, you can't break the encryption, only by stupid luck and that is still a nearly impossible chance... You have to look to find an opening around the bootloader, classic approach, take out the encryption validation from the bootloader and you can load custom sizzle.. You need a bench, diagnostic tooling and time to fully understand the OS... Assembly knowledge would be very usefull, but first step is to understand how the TCU operates, firmware updates, reason why firmware has been updated (Potential weakspots) ... Or insight knowledge.. Bribe somebody ;-)

    Chances are these guys have some very high end software "specialist" that were able to beat the encryption, and then worked with a Jailbreak "tuner" to modify some of the OEM tables. This is how it starts, so more people work on it, it'll slowly get more and more refined, in addition to more control over the OEM tables.

    Switzer (obviously more well known for their GTR packages) has started advertising power packages for the Turbocharged M cars2 problems with this -- 1) Kills resale value & backdoors BMW into making sure when the car is sold, that someone doesn't try to sell the car with a "warranty" and 2) how to do you prevent someone basically "copying" the unlocked code onto a car that is still technically covered under manufacture warranty?Puts a LOT of responsibility on the manufacturer that they just don't want to waste their time (and money, and resources) with.
