Lauch control - not disengaging

I would assume it does not see wheel speed like mapper has mentioned. You could also be hitting a limiter somewhere else. Check to make sure that this is not interrupting the launch control. I.E. you think it's launch control when really it is a completely different limit activating. Most likely wheel speed but can never be too sure.

Check under the chassi setup if non-driven wheelspeed is setted up. You can confirm correct reading under F12 tab or in a datalog. 

You are spot on, it hasn't been setup.

Apologies for the newbie question, what would the "non driven wheel speed source" be on an all wheel drive car?

It's a good question, there is no non-driven speed source on an all wheel drive car. You can set the non-driven speed source to be the same as the driven speed source, however there will never be any slip, and if using it for launch control the launch control will disable if your driven speed source is faster than the threshold you have set.

Alternatives could include taking non-driven wheel speed source from a ground speed sensor, or a high speed GPS. Or you could use a timer or some other condition (gear?) to disable launch control.

Scott.
