sweet as
have you also tried to disable the DBC?
(dynamic brake control) (pre charges the brake when you push it really hard and fast)
The function you need to set to not active is BB_RAB found in the MK60 ecu. (not my findings, but Tom K's from over the pond)
Havent done it yet, but looking at doing both of these, although ive been fine with Traction OFF as it doesn't rain here. Track mode with rain looks like an awesome add-on.
