LNC-001R description:
Sometimes referred to as a 2-step or launch controller, the LNC-001 can be used to provide consistent launch rpm off the line in drag racing and standing start road racing applications. In turbocharged applications the use of the LNC-001 also allows the engine to build more boost off the line during the launch.
The LNC-001 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.
Ff the two don’t completely cut fuel at the same time, instead of having an RPM limiter you will likely go dangerously lean, risking severe engine
damage.
With the new Timing Retard function, the LNC-001 can now also be used to retard timing by up to 10 degrees. This can be used to retard the timing when you trigger a nitrous oxide system or to retard the timing off 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.
If you are an existing LNC-001 customer that purchased your LNC-001 before the Timing Retard function was introduced, you can send your LNC-001 in for a software update and then you will have the new feature as well.
The LNC-001 is designed for use on all GM LS series engine applications (LS1, LS6, LS2, LS3, LS7, LQ4 and other Gen III and IV GM V8 applications along with other GM V8 engines using the same ignition coil system) including the following vehicles:
· 1997-2004 C5 Corvette
· 2005-2008 C6 Corvette (including Z06)
· 1998-2002 LS1 V8 equipped Camaro and Firebird
· 2004-2006 Pontiac GTO
· 2004-2006 Cadillac CTS-V
· 1999-2008 GM CK trucks (Tahoe, Yukon, Escalade, H2, Sierra, Silverado, Avalanche) with the 4.8, 5.3, 6.0 and 6.2L Gen III and IV V8 engines (will not work on 305 & 350 Vortec engines)
· 2003-2006 Chevrolet SSR
· 2006-2007 Trailblazer SS and other S/T body trucks with the 4.8, 5.3 and 6.0L Gen III engines
The LNC-001 should function on these vehicles but has not yet been tested on them:
· CK trucks with 8.1L V8 engines (L19) with individual coil ignitions
· front wheel drive 5.3L LS4 Gen IV V8 equipped cars (Impala SS, Grand Prix & Monte Carlo)
The LNC-001 should function with these products but has not yet been tested with them:
· aftermarket coils for the LS series engines used with the factory PCM
· aftermarket engine management and ignition systems Accel, BigStuff3, Motec, FAST, MSD,
that run the production GM coils.
Installation
No coil wires need to be cut, just disconnect the coil pack connectors on each side of the engine and then plug the LNC-001 wiring harnesses in between on each side.
The only wiring that is required is for the trigger wire(s) depending how you want to enable the device.
Ground activation wire
+12 volt activation wire
Switch between the two wires -usually a momentary switch
Ground wire connect to +12 volt wire for standard rpm limiter operation -always
active

Specifications:
· 40 MHz 16-bit automotive qualified processor with eight channel Enhanced Time Module.
· Each coil drive circuit has a dedicated timer to keep the timing accurate over the full RPM range.
· Independent coil drive provides Sequential Ignition Kill when RPM limiting is active.
· Reverse battery protection.
· Both of the activation inputs have active clamps and optical isolation to suppress electrical noise from external solenoids (such as trans brake and line lock).
· Digital filter provided in software to further isolate electrical noise on the activation inputs.
· Both Ground Activation and +12 Volt activation inputs are provided to work with existing vehicle wiring. Both activation wires may be connected together to enable activation. This allows for the use of a momentary
switch for activation.
· The LNC-001 can be adjusted from 1500 rpm to 9,900 rpm in 100 rpm increments by the two 10 position rotary switches found inside the module.
· True plug-and-play design for ease of installation and removal.
· Fully encapsulated or potted construction for added durability.
· Rated for operation at up to 185 degrees F (85 degrees C).
· 90 day warranty from date of purchase
Please note - although launch controllers like the LNC-001 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-001 only has one rpm limit setting so if you are using the LNC-001 as a launch control rpm limiter, you will need to use the factory ECM/PCM as the engine maximum rpm
limiter.
Warnings for use of this product-
Because the LNC-001 acts by disabling spark to individual cylinders, not by disabling
fuel like a production RPM limiters it is not meant for use on the street or for use on cars equipped with catalytic converters.
The LNC-001 is only for use on race vehicles on the race track. Failure to follow these precautions
will result in premature catalyst failure. DO NOT operate the engine with the LNC-001 active for extended periods of time. Because of the raw fuel entering the exhaust, a risk of backfiring exists if you do so.
