Launch control

1. How does it work, is it fuel cut or ignition cut?

2. How do I use it with the frequency input? If pull-up, how?

1) LC in DET3 is ignition cut. DET3 cuts signal from CKP sensor / or signal to ign module (the best results)
2) For frequency input connect frequency input with the DET3 pullup output, then activate it by switching ground.
