    • 2010 on E93 (convertible) M3 with "locked" ECU dyno test featuring OE Tuning tune only

      The E93 M3 in question here is a manual. It is completely stock and on 91 octane pump gas. The reason the year is emphasized as being a 2010 on is due to the tuner lockout software BMW implemented to try to stop tuning with cars featuring 2010 and up build dates. These locked ECU's have stopped some tuners but the as the graph and video here shows OE Tuning is able to circumvent the lockout and custom dyno tune the car. Gains are shown throughout the curve with a healthy 21 wheel horsepower at peak, tune only.

        That is good work. The Cabriolet needs some more hp
        as the RHT Click here to enlargeweight is a huge penalty. Add some hardware and it would be even more beefy. Click here to enlarge

        Does the ECU have to be removed to tune? Good gains!

        Good question but wouldn't you know being a tuner?

        Tuner proof can be done with a certain cable in person. But most would need to send in that aren't local to this tool as it is several thousand dollars and licensed to the computer - not something that is portable without a major deposit.

        I see, interesting.

        Can't someone just set their ECU back to an older revision so they don't have to send it in?

        Well that's essentially what the tuner proof cable does, writes to a pre-lock version. BMW does not go backwards with updates. You can only write the latest and greatest.

        I see, so they get the cable and do whatever needs to be done then it can be remotely flashed. If they don't use the cable, send the ECU in, right?

        Correct it would need to back-dated first.
