Improving your cars 60 ft and 0 60 times can improve in ways you never thought possible just by setting up 2 step.
Diy 2 step rev limiter.
An aftermarket two step rev limiter lets you set one lower limiter for launch and a higher limit for when you re upshifting as you accelerate away.
Adjust shift light to desired rev limit.
This also activates the boost vs time function as well.
This is where a 2 step rev limiter can really shine.
Hook the 85 and 86 pins of the relay to the shift light on the tach and have the igt signal for a toyota run through the 87a and 30 of the relay.
The reason why is that you can build boost pressure on the starting line with no load on the motor by setting up the 2 step limiter with the right parameters.

To have it work as a launch control flat shift or what some call a 2 step have the tach powered only when the clutch is pushed in.
A changeover relay these differ from normal relays being 1 circuit is always active.
