Lingenfelter L460145297 Lingenfelter LNC-2000 LS Timing Retard Launch Controller v2.0 - Manual (Page 4)

LNC-2000 description:
Sometimes referred to as a 2-step or launch controller, the LNC-2000 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-2000 can also be used to retard the timing in order to build
more boost at the line.
The LNC-2000 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-2000 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-2000. This dedicated timing retard activation input can be activated using clutch or accelerator pedal
position via a micro switch or the Lingenfelter CTAP-001 clutch and throttle activation position switch (PN:
L460190108). The LNC-2000’s timing retard activation input can also be activated via a +12v activation signal
from a nitrous controller, such as the Lingenfelter NCC-001 or NCC-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-
2000 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-2000 are often referred to as 2-step controllers, they
are not true 2-step controllers. A true 2-step controller, such as the LNC-003, has a high and a low RPM
limit function with a switch of some type enabling one setting or the other. The LNC-2000 only has one
RPM limit setting so if you are using the LNC-2000 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-2000 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-
2000 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-2000 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-
2000 are sealed but are NOT rated for high pressure wash, use caution if power washing near the LNC-2000
