The Launch rpm setting can be adjusted manually in 100 rpm increments from 1,000 – 10,900 rpm with the two control dials. Adjustments can be made with the engine running or with the ignition On.

1. Connect the Manual Launch Control to the MSD Ignition with the 9-Pin Harness.

2. When the ignition is turned On, the LED will blink then remain On.

3. When either rpm control dial is rotated, the LED will blink once indicating that the new value has been programmed and accepted in the Ignition. If the LED continues to blink, that indicates a faulty switch position or connection.

Note: When disconnect ed, the last

launch rpm limit set will be programmed into the ignition.
