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.
