Hi, it would be a usefull feature if the “sensors-\>vehicle speed” could be also set additionally to “max. of undriven axle” or just a “custom cannel”. The background of this request is: When driving with ESP and the ESP locks the unloaded front wheel the detected slip gets very high causing the TC to react harsh although there is no wheel spin on the (rear) driven axle.
