two rotary switches located on the harness side of the unit. The adjustment range is from 1,000 - 10,900
rpm, in 100 and 1000 rpm increment, an LED will illuminate when the launch rev limit is active.

Parts Bag:
Note: The engine rpm must drop more than one third of the set launch limit in order to activate. For
example, if the launch limit is set at 3,000 rpm, the engine speed must drop below 2,000 rpm
in order for the launch limit to become active (one third of 3,000 rpm is a 1,000 rpm drop).
The built-in LED will illuminate when the 2-Step Launch Control is activated. It will also, illuminate
when there is no rpm signal.
