Default OBDII CAN Flap Module for F Series BMW - 02-07-2015, 12:56 PM

Hey guys,

We'll use this thread as the single point of contact for anything CAN module related.


Exhaust Valve Mode:

Toggle between flap open, flap closed, and OEM operation, by pressing the BC button for 2 seconds. The left blinker will flash for valve open, right blinker for valve closed, and both blinkers for OEM operation. The valve setting is persistent and will remain in effect until you change it. Note if you hold the BC button down too long you will enter the menu system below.

Menu System:

To enter the menu system press and hold the BC button until both arrows flash and the tach drops to "ready". Press and quickly release the BC button to toggle between different tach selections or menus. As you toggle through the menu selections documented in the list below your blinkers will indicate left for enabled, right for disabled, or both for undefined/unused menu. If you toggle past the last menu it will wrap back around to menu 0. To change a menu selection press and hold the BC button while you're focused on that menu. This will trigger the system to switch the blinker position and exit menu mode. Note holding the BC will change the status of a menu on all menus except for menu 0 and undefined menus where both blinkers are on. So if you wish to exit without changing anything, for example if you entered the menu system accidentally, simply press and hold the BC button on menu 0 and you'll exit out.

0: Undefined/Unused.
1: Active Sound MUTE - When flap is open full time
2: Active Sound MUTE - When flap is closed or OEM operation
3: Boost gauge on fuel, scaling 0-20psi, activates when boost goes over 5psi
4: Delete Diagnostic Faults
5: LED HALO Max Brightness at Night
