link linelock switch with 2-step launch control with your ignition box...
Mash throttle whilst preload trans on linelock/brakes
let go of clutch and linelock simultaneously and unleash your beast!
I've always wondered whether you could even use a linelock on a hydraulic clutch and literally launch on a single button...?
thats a quite interesting idea, and it could work, releasing pressure on clutch and brakes in one go sounds fast ans quite easy to do. but maybe too much help there will be and less human power involwed in the driving
