    • Motec's M182 standalone ECU supports direct injection - Turbo upgraded BMW F30 335i with Motec controlled N55 and 600 horsepower

      Getting control of the BMW factory DME is a huge pain. With the F30 generation BMW upped their encryption and to this point nobody has cracked BMW's protection. What is one to do? Well, there are piggyback options but for those who want full control of their motor that will hardly do the trick. The Motec M182 standalone (takes the place of the factory ECU) is an option in these situations although at a pricey 4,552.00 Euros ($6200.00).

      The F30 335i you see below has its N55 turbocharged and direct injected 3.0 liter inline-6 controlled by the Motec M182. You will also notice it is a stripped out race car. So how does the M182 help a street application? Well, it does not help you if you want to retain all of your OEM electronic systems.


      However, a future answer for those who want to do turbo upgrades on the F30 335i and F32 435i may be relying on such an ECU run in conjunction with the factory DME. The Motec ECU in such a scenario would handle the engine management while the BMW engine computer would make sure all the factory electronics still play nice. This sort of dual ECU solution was employed on the E46 M3 early on with turbo kits and Motec ECU's are used in the high powered Lamborghini and Ferrari Underground Racing turbocharged street cars we all know and love.

      This may be the route tuning takes as it is just now the factory computer on the over a decade old E46 M3 is decrypted to the point of allowing turbo kits tuned on the factory DME. With F30 encryption being even more difficult to crack does anyone really want to wait around for 10+ years (could be far less, could be more) for factory DME tuning to evolve to the point of supporting a turbo upgrade?

      Fortunately companies like Motec continue to deliver engine control systems that can support modern engine management. It's up to the BMW aftermarket to figure out how to best integrate them.

      Look at this dyno of M182 controlled N55 with upgraded Borg Warner turbocharger (stock injectors and fuel pumps) versus OEM DME controlled N55 with the factory turbocharger. This previews what the N55 is capable of with a turbo upgrade. Horsepower is 599.4 with torque at 629 pound-feet:

        If you're open to giving up all your comfort features (NAV, Sound System, Comfort Access, etc) & hack up your dash to use a Digital Gauge Display, then yea it is the ultimate performance car solution.

        But that's a big jump to make in a 335 when you could spend a little extra coin on a 996 Turbo/GTR & keep all your comfort features, while doing something simple like a bolt-on car or an all out 1k WHP killer.

        It's at BMW's request. Siemens doesn't provide all the software BMW programs it.

        Or you could get a Mustang and beat them all. How does this help the F30?

        ....Never said I was pro-F30. Personally I'm even less pro-F30 (and BMW if they're gonna keep up this software "war" against owners trying to modifying their cars) if means dumping $10k into it on a standalone EMS & render every factory feature useless to modify it.

        I can understand that BMW's concern (from a business perspective) is now that 99% of their cars are turbocharged from the factory, they don't want owners "messing" with their product and then attempting to get any failures/broken parts covered under warranty, aka on BMW's dime.

        I just don't see the point of suggestion F30 owners should go buy a used decade plus old 2 seat Porsche as a tuning solution for a 3-Series. It's like someone asking for ketchup on their hamburger and instead they get handed yesterday's burrito.

        Alright, so if you want to buy & modify a brand new German automobile, Audi & Mercedes are clearly much better options since they are much more aftermarket friendly.

        That makes more sense.

        maybe I missed it, but is it mentioned anywhere what turbo setup this car is actually running?

        I don't think the specific model of the turbocharger is mentioned.

        Well 600 WHP+ has been done on the N54 on a kill setup with a Precision 5862, which moves 64 lb/min. So a comparable Borg Warner is the EFR 7670.

        IN the original link I posted in the other thread, link, all he states is that is a Borg Warner EFR Turbo with external gates (Twin scroll).

        This has been the case for years with Toyota ECUs.

        Most of the modern Supra guys run standalone for the features they can't tune on the stock DME, specifically FlexFuel, Anti-Lag/2-Step Launch & Traction Control.

        Single Map Tuning & Boost Controllers are nice and completely capable of doing the job reliable, but it's certainly not as safe (nor will it truly showcase your setups' potential) as any of the current standalone options -- ProEFI, AEM Infinity, Syvecs, etc.

        **Motec still does not support FlexFuel

        As far as I know the oem supra ecu is not flashable.
