I used a kind of OEM looking lighted switch along with a relay to bypass that signal on command, like at the dragstrip. There are no lights or faults associated with this when I hit the switch, because all I'm doing is bypassing that push switch.
It rained this morning so I went out and tried it, and it works perfectly. Hit the switch, hold the brake firm and gas at the same time with your right foot (around 3500rpm) then dump the clutch. The car shouldn't move.

I have some pictures of the process if somebody want to see them.
