I'm not sure if the 2011 GSR's are different but I don't have to hold the button down for 3+ seconds for the launch control to enable. If I hold it down, it beeps and then a yellow AYC off light comes up on my dash. Is this what you mean?

 

I use launch control on the strip normally with 340hp and stage 2 exedy. Anyone have a comparable setup? My cluctch and/or diff makes a bad sound under heavy load...

 

hold the button for 3+ seconds to completely disable traction control

factory launch control is always on and set to like 5500 rpm imo its a clutch destroyer

 

ok so what is the difference between disabled and completely disabled? meaning what's the difference between hitting the button normal and holding the button for 3 sec? (not being sarcastic at all)

 

It probably says in the manual. Ive always just shut it off completely so my lap times dont suck.
