LNC-TC1 description:
The LNC-TC1, or Torque Cut Module, is designed to provide a momentary torque cut on GM LS based
engines using the OEM style ignition systems. This momentary torque cut is usually needed when using
dog-engagement or other clutchless shift type transmissions.
The LNC-TC1 also has an RPM limiter feature that can be used to provide a reliable and fast acting
spark based individual cylinder RPM limiter. This RPM limiter can function as a traditional engine
RPM limiter or it can function as a 2-step or launch controller in order to provide consistent launch
RPM off the line in drag racing and other standing start racing applications.
WARNINGS:
The RPM limiter and the torque cut functions of the LNC-TC1 act by disabling spark to
individual cylinders so the torque cut and 2-Step/Launch Control functions are not meant for use
on the street or for use on cars equipped with catalytic converters. The torque cut and 2-Step/
Launch Control functions of the LNC-TC1 are only for use at the race track on race vehicles
not equipped with catalysts. Failure to follow these precautions can result in premature catalyst
failure.
DO NOT operate the engine with the LNC-TC1 RPM limit active for extended periods of time.
Due to the raw fuel in the exhaust when the RPM limit is active, a risk of backfiring exists if you
do so.
DO NOT place in direct exposure to exhaust manifolds, turbocharger turbine housings or other
underhood items that are high temperature heat sources (radiated heat sources). The warranty does not
cover damage due to melted enclosures or wiring due to improper installation.
Do NOT submerge Controller in liquid or directly wash unit with liquid of any type! The switches on
the LNC-TC1 are sealed but are NOT rated for high pressure wash, use caution if power washing near
the LNC-TC1 controller
Important Information regarding spark plug wires and spark plugs:
You must use noise suppression ignition wires AND resistor type spark plugs with this Controller. The
LNC-2000 Controller contains High Frequency Digital Electronics and will NOT function correctly
without Noise Suppression Wires or resistor type spark plugs!
