2-Step Rev Limiter
The TR6 has a built in 2-step rev limiter that is used to build boost when staging/racing. The trigger wire is the orange wire in the system harness, pin 1. To use this feature, first set the limiter RPM dipswitches. See the introduction section for help in setting the switches. When the trigger input is activated, the engine RPMs will be limited to the set value. When the trigger is active, the Trig/Error LED will glow SOLID. When the system is limiting RPM, the Trig/Error LED will flash quickly. (When not triggered, the Trig/Error LED will flash quickly when the main rev limiter has engaged.) The trigger is normally activated by applying voltage to the trigger wire. If the Invert Trigger switch is ON, then the trigger is activated when there is NO voltage applied to the Trig input. The Config-1 switch can be used to supply “Pullup Voltage” to the trigger input so that “Grounding” the trigger input will activate it. If the Trig Limit switches are all set to OFF, then by setting the Config-2 switch to ON, and connecting an MSD “Pill” from Analog input 1 to ground, the Triggered RPM limit (2-step) can be controlled remotely.

7
(RPM must be greater than 1500). Mode 8 retards 5 degrees, Mode 7 retards 10 degrees, with both Mode 7 and Mode 8 on, the TR6 will retard 15 degrees.
