Rolling launch won't activate.

Post by vongdong »

I've got it set to the brake switch to activate but it doesn't work. I'll drive it up to around 4K rpm, touch the brake and floor it (set at 5400rpm) but nothing happens. Car just pulls like normal. I've got the speed set up high so that's not the issue.

Standard (<5kph) launch control works though when I have it set to always on.
Using the latest Kmanager and Kpro V4.

I'm not sure I understand what it is that you are trying to do.

Use a different input and wire it accordingly. If the Brake switch is used it can no longer be connected to the brake pedal and will interfere with the brake lights

Only input i think would be good is the service connector switch. How would i wire that? My momentary button just has 2 prongs so one to the scs wire and the other to ground?

The switch should just complete the circuit to ground if it is a ground input.
