    • Poll of the month - How do you feel about BMW anti-tuning?



      This is our question of the month for September 2010. BMW is increasingly taking measures to make it difficult to tune the cars. This goes against the very spirit of BimmerBoost and the BMW enthusiast. We don't want them to continue taking control away from us as well as hurting the aftermarket. We do understand the need for BMW to protect themselves from people who abuse leases, but what about the person who intends to buy and keep the car? Should they not have the option to buy with an unrestricted ECU foregoing partial aspects of the warranty?

      If BMW keeps this up, I may end up in a different car. Even Mercedes is rumored to be getting in on this with ECU's that won't be tuneable. American manufacturers embrace enthusiasts, Ford is offering factory supercharger options for the Mustang GT. If a user wants to get really crazy with it, they can forego their warranty and get a max performance setup. Ford gives users the choice. Chevy even allows performance engine owners to build their motors themselves if they want to. BMW is making changes that are best for their bottom line but spit in the face of their most loyal, dedicated fans. The best BMW has done for us is offer some Motorsport parts but those hardly consist of superchargers or turbos. How do you feel about it?

        There's no black magic to BMW tuning or any other make. There is no BMW processor I can't read/write presently. We're talking about other makes/models.

        Thanks

        Piggybacking isn't remapping. Standalone engine management should/will work, but I don't know of anyone that's done that yet with a Panamera Turbo, etc. That's not the road many owners really want to take, though they may be forced to soon.

        There are canbus tuners (MTM, APR, etc) but they aren't making any power and that's not real tuning.

        Besides the 3.0 B8s make 400-415HP stock, they are horribly underrated from the factory.

        Trust me it hasn't been hacked and the gen II and III SE processors are even worse.

        I've been hearing the same lines regarding (the people that make them at night come home and reverse engineer them), in this case and in the future, no they don't. It's not like it used to be. Leaking out encryption keys is step 1 of 100.
        Your statement is VERY inaccurate. APR has hacked the B8 S4 Ecu. Infact I am the first one to have it in DSG format. No piggybacks, strait flash. Saw it with my own eyes in Alabama when I went down to their facility. Also should mention that they are doing all flashes in house on the bench (with, or without the car) and therefore aren't hiding some piggyback in the car.

        Yes they are under rated but not by as much as you imply. They make 320's at all four stock and 360-370's with a tune. But the power curve above 5K is where the power really is. Just look for yourself on goapr.com

        What year/month production is your S4?

        Why not just a compelet OE replacement with the ability to be tuned? Why reflash the stock when you could just replace the whole unit. I mean it will be a huge PITA to make one. And it will have to controll everything else in addition to the motor but none the less if your getting no where with the stock ECU why spend the time and money to hack something when you could just build a new one.

        You are saying complete ECU replacement? As in standalone?

        Yes correct a stand alone replacement. I guess I should have called it that lol.

        The reason that standalones are not more prevalent as you lose I-drive and all kinds of other electronic features. There also is no straight answer on compatibility with DCT.
