DIY - Launch Control

UPDATE:

Ended up changing the switch on the Clutch for a old Brake switch off another ae92.
This went straight into a bolt hole that the clutch pedal has already. Plug & Play.
And then went and tidied up all the wiring and mounted the power switch for the unit in a nice hidden place. (Im not into big flashy buttons/switches everywhere, like to keep it subtle.)


As the title says, its time for DIY - Launch Control.
All launch control is, is a rev limiter set to what ever you want to lauch from.
And to do this i bought a Frequency switch from Jaycar, or one can be made like this website.

But the unit was on special so i decided to go with that.
Frequency Switch - Jaycar

To allow for it to be used as launch control, a switch is needed on the clutch so when depressed it is active, and when your off the clutch it is deactivated. (This is so you can carry on reeving through)




So to do this i had an old pull switch from my motorbike, that i made a bracket to fit under the dash by the clutch pedal.

And then the rest of the unit needs to be wired to the coil negative, as this is the 'frequency' it uses.
And then 12v and a earth.
And then setup the frequency switch to earth out the coil when hitting a certain rpm, this is done by adjusting the pots inside the unit.
