    • COBB Releases N55 Accesstuner Pro and updated N55 OTS maps!!

      COBB is excited to announce substantial updates for the BMW platform! Available immediately are updated N55 OTS maps including Stage2+FMIC along with Accesstuner Pro support. The N54 software is also receiving a minor update to available tables. These N54 tables include new ignition timing discoveries and are hit in very rare cases, but we want customers to have access to anything that may help a particular vehicle. We also created 3D fuel scalar tables for all rom versions. This will allow better control of fuel trims with more precision than the old single cell value.

      N55 Map Updates:
      We have implemented new DME logic that solves potential load calculation issues. If you are currently running a v100 map you will need to completely uninstall the Accessport from your vehicle and reinstall using an updated v200 map.

      In order to take advantage of these updates, please ensure your Accessport Manager software is updated first, followed up by updating Accessport firmware using Accessport Manager.

      Note: Due to new DME logic, we are no longer providing a Stage0 map for N55 only.

        N54 still has the limits we've been working with... for now.

        N55 limit is very high though.

        ATR will be released very soon, most likely before the end of the year. In the meantime, here's some good reading...

        Yea, being able to modify all the tables is really gonna push the limitations and help us find the limits of the stock turbo on a variety of setups (pump fuel, race & E85).... It'll also be a HUGE now that upgraded turbos for the N55 are on the horizon
