I am having trouble finding these maps in both the XDF for the M-box and the CH (1.8t) box.  I would like to bring the values from the CH box over so I can start logging gears also.

From the WIKI:

"Gear detection
The ecu computes the gear (gangi) from the quotient N/V out of nmot_w and vfzg_w. To find the current gear, the ecu uses for each possible gear a min and a max quotient to compare the actual N/v against.

You have to update these quotients in order to map with the present gearbox/wheels. The thresholds are named NVQUOT1O (upper quotient for 1st gear), NVQUOT1U (lower quotient for 1st gear) up to NVQUOT6O, NVQUOT6U for 6th gear.

NVQUOT1O (0x013BC2)
NVQUOT1U (0x013BC4)
NVQUOT2O (0x013BC6)
NVQUOT2U (0x013BC8)
NVQUOT3O (0x013BCA)
NVQUOT3U (0x013BCC)
NVQUOT4O (0x013BCE)
NVQUOT4U (0x013BD0)
NVQUOT5O (0x013BD2)
NVQUOT5U (0x013BD4)
NVQUOT6O (0x013BD6)
NVQUOT6U (0x013BD8) "
