Adjustable Launch Controller, RPM Limiter 2 Step & Timing Retard

Lingenfelter Adjustable Launch Controller, RPM Limiter 2 Step & Timing Retard LNC-002

Sometimes referred to as a 2-step or launch controller, the LNC-002 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-002 also allows the engine to build more boost off the line during the launch.

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 do not 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 Timing Retard function, the LNC-002 can now also be used to retard timing by up to 15 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.

The LNC-002 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

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

Timing retard capability with up to 15 degrees of timing retard authority.
Dedicated timing retard trigger input wire for nitrous activation or other timing retard activation.
GM 3 bar manifold air pressure MAP sensor connector for boost based timing retard function.
Analog voltage output wire for sending timing retard information to data acquisition systems EFILive, HPTuners, DashDAQ, etc.\
True plug-and-play coil pack connection design for ease of installation and removal.
Fully encapsulated potted construction for added durability.
Rated for continuous operation at up to 185 degrees F 85 degrees C.
90 day warranty from date of purchase.

Switches and indicator lights Red (Power) LED:

Comes on solid on start-up (power on)
When active RPM is reached, red LED will blink even if activation wire is not triggered.

Green (Activation) LED:

slow blink indicates launch activation only
medium blink rate for Retard Activation only
fast blink rate for both launch and retard inputs on

Settings:

Controlled by two (2) ten position switches (RPM) and two (2) sixteen position switches (Timing)
Two (2) ten position switches for selecting hundreds of RPM (x100) and thousands of RPM (x1000)
Two (2) sixteen position switches for selecting retard Degrees and timing retard Rate

Notes:

The LNC-002 RPM limiter function will not trigger at RPM levels below 1500 RPM
The LNC-002 timing retard function will not retard timing below 1000 RPM
Changes to the switch point settings (RPM, Degrees, Rate) must be done with the ignition off
The switch positions are only read on start up

Current versions do not work on 2009 CTS-V LSA engine or 2009 C6 ZR1 LS9 engine.

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-002 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
Example wiring diagrams for clutch switch, line lock and nitrous configurations included in supplied installation instructions

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.

Warnings for use of this product
Because the LNC-002 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-002 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-002 active for extended periods of time. Because of the raw fuel entering the exhaust, a risk of backfiring exists if you do so.
