LNC-002 description:
Sometimes referred to as a 2-step or launch controller, the LNC-002 adjustable RPM limiter and timing
retard controller can be used to provide consistent launch RPM off the line in drag racing and other
standing start racing applications. In turbocharged applications the LNC-002 can also be used to retard
the timing in order to build more boost at the line.
The LNC-002 can also be used as an adjustable individual cylinder RPM limiter, providing reliable
and fast acting spark based engine RPM limit control. This is especially useful in vehicles that have
auxiliary fuel control systems where it is not possible to make sure that both the factory ECM/PCM and
the auxiliary systems both turn off fuel at exactly the same time. If the two don’t completely cut fuel at
the same time you will run lean when the one system cuts off the injectors (but not the other), risking
severe engine damage.
The Timing Retard capabilities of the LNC-002 can be used to retard timing by up to 15 degrees. For
nitrous oxide applications the timing retard can be activated using the dedicated timing retard activation
input to the LNC-002. In turbocharged and supercharged engines the amount of retard can be controlled
by the boost level using the 3 bar MAP sensor input. The LNC-002 can also be used to retard the
timing at the line to build boost in turbocharged vehicle applications (with or without the launch control
RPM active). The Timing Retard function can be used by itself or while the launch control RPM limit
function is active.
Please note - although launch controllers like the LNC-002 are often referred to as 2-step
controllers, they are not true 2-step controllers. A 2-step has a high and a low RPM limit function
with a switch of some type enabling one setting or the other. The LNC-002 only has one RPM
limit setting so if you are using the LNC-002 as a launch control RPM limiter, you will need to use
the factory ECM/PCM as the engine maximum RPM limiter (engine speed governor).
WARNINGS:
The RPM limiter function of the LNC-002 acts by disabling spark to individual cylinders and not
fuel like most production RPM limiters so the 2-Step/Launch Control function is not meant for
use on the street or for use on cars equipped with catalytic converters. The 2-Step/Launch Control
function of the LNC-002 is 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-002 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-002 are sealed but are NOT rated for high pressure wash, use caution if power washing near
the LNC-002 controller
