    • 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:

        As far as I know the oem supra ecu is not flashable.
        How the hell is that possible?

        For the Tundra?
        Yup. Tundra, Tacoma, Sequoia, 4Runner

        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.
        Ehhhh. Disagree. Audi is actually flagging cars w tunes. They have service bulletin about it. I forget the number.

        Also. I think Audi's are $#@! quality based on my experience and those of my family and friends.

        No experience w Mercedes.

        It's at BMW's request. Siemens doesn't provide all the software BMW programs it.
        As it was explained to me by people who know, Siemens offers the encryption level to all OEM with whom they deal. BMW elects to take it. It is software, but also requires certain hardware which Siemens supplies. Once th encryption is on board of the DME, it makes no sense for an OEM not to use it.

        For BMW, it has been there since late spring of 2012. 2014 had nothing to do with it.

        Yeah, the 3.0T (and almost certainly others) has had problems for years with people just not understanding that if you flash it and bring it in for service, it gets hooked up to a diagnostic computer which looks at code somewhere and can tell if the car is flashed. If it's flashed, that diagnostic computer immediately sends a report to Audi HQ in Germany and they flag the entire powertrain "TD1"- tune detected- and your powertrain warranty is toast.

        All this wouldn't be such a problem if people understood to flash back to completely stock (not stock maps with tune installed) before service and if APR and GIAC would offer flash-at-home handhelds like Cobb. But since they dont, and there's no usable piggyback offering, Audi owners are in the cold. Stage one tunes are $1200+, additional maps cost $$$ and most flash tune installers charge $ to flash back to stock. It's the dark ages. A pretty large number just seem to wait until the warranty is up before tuning which is crap. They desperately need JB4 love @Terry@BMS or Cobb both both seem to have zero interest in anything VAG.

        Pretty sure this is a little off..... Not sure about APR, but I know EVOMS + GIAC both offer "at home tuning solutions" via a computer module and OBD cable (exactly like how people load E9x m3 tunes). Obviously it's no where as convenient as the COBB AP/OBD cables, but it's still significantly more convenient then having to see your tuner everytime you want to go back and forth.

        But like you started with, the real root problem is most of the people don't bother to fully install their tune before bringing the car for service while still under the original factory warranty.

        The TD1 works in reverse, the ECU keeps date stamps of the changes that are non dealer. This goes online to Germany and it comes back TD1. On the slightly older scars you could do a full write to the car via BDM on the bench and you would be safe. Current cars that I know have all been caught.

        I never heard of EVOMS but their website showed a bench flash for the 3.0T. GIAC has a handheld map switcher but that just changes maps AFAIK and you need their flash code on the ECU for it to work. Like APR and others, I believe GIAC needs to flash the entire ECU back to a stock file for you to go through service without being detected.

        These modern ECUs are a bear. The newer N63 or S63 supposedly has twin ECUs. WTF?!

        I have zero experience with all of this 3.0T VAG stuff other than owning a stock S5 with nice aftermarket wheels and RS5 grill but from what I've seen on the Audi forums, this doesn't seem to be the case. Several people with 3.0T claim to have flashed APR or GIAC, flashed back to stock and went through dealer service and supposedly had no issues. I'd have to dig through the posts but I could swear that covered both the B8 and B8.8 (2013+) ECUs. It's hearsay to me though until it becomes more widespread or I know someone who's done it and it worked or did not.

        I do not disagree but what do you mean about 2014?

        The guy who mentioned the Audi service bulletin is right, they are trying to flag cars. Audi isn't much better than BMW.

        All I have to say is MoTeC is the $#@!! I have an M130 on my seadoo and it hands down was the best thing I ever bought. The data logging and ability to control basically any parameter with a couple mouse clicks is out of this world. If I had a BMW, I would get this in a heartbeat. I don't see many 1 and 3 series owners springing for this though. Still cool

        I am glad you like the M130, I learned a lot from Pete at MoTec he is a very smart Guy.

        Am I the only one that thinks this thing looks really similar to the new Dinan piggyback ecu for N55?

        I guess I'm a little unsure after reading through the thread...
        At the beginning, there was a suggestion that you could run the motec in parallel with the oem ecu, but then later comments, such as post #20 by sticky, suggest it's only useful for a somewhat gutted track car. Another comment suggested you'd have to give up all of the oem dadhboard functionality.

        Any further clarification possible on whether a true tandem ecu set-up that retains basic oem dashboard functionality is realistically doable?

        To retain the OEM functions someone will have to figure out how to get this ECU to work in parallel with the factory DME. Right now, this is primarily a track car solution.

        Someone mentioned it earlier in this thread as the initiation date of the RSA 1024 encryption standard. It started in late April with the N55.
