Diy 2 step rev limiter.
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.

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.
Thank you very much for your input.
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.
A changeover relay these differ from normal relays being 1 circuit is always active.
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.
Here is what you need.
This also activates the boost vs time function as well.
This is where a 2 step rev limiter can really shine.
