LS1, LS6, LS2, LS7, LS3, LQ4, L76, L92, LSA & LS9

Easy way to take out timing for nitrous applications.


Sometimes referred to as a 2-step or launch controller, the LNC-2000 and LNC-2001 are adjustable RPM limiter and timing retard controllers that can be used to provide consistent launch RPM off the line in drag racing and other standing start racing applications while also providing timing retard capabilities for a variety of applications.

Two models exist, the LNC-2000 and the LNC-2001. The LNC-2000 is for most GM Gen III & IV V8 engine applications and connects to the standard coil pack harnesses found on these vehicles. The LNC-2001 is specifically designed for use with the LSA engine found in the 2009-2014 Cadillac CTS-V and the 2012-2014 Chevrolet ZL1 Camaro and with the LS9 engine found in the 2009-2013 Chevrolet ZR1 Corvette. The LSA and LS9 engines use different coil pack harness connectors compared to what are used on most other Gen III & IV GM V8 engines.

The LNC-2000 or the LNC-2001 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 and LNC-2001 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. This dedicated timing retard activation input can be activated using many different methods including clutch or accelerator pedal position via a micro-switch or the Lingenfelter CTAP-001 clutch and throttle activation position switch (PN: L460190108). The timing retard can also be activated via a ground or +12v activation signal from a nitrous controller. When used in conjunction with the Lingenfelter NCC nitrous controller, the LNC-2000 and the LNC-2001 allows progressive timing retard tied to the nitrous percentage via an analog input signal. 

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 and the LNC-2001 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.

The timing retard can also be controlled by external traction control products like the Davis Technologies line of traction control modules. In these applications the external module uses the timing retard feature of the LNC-2000 or LNC-2001 to reduce engine power in low traction conditions.

Additional Notes:

Although launch controllers like the LNC-2000 and the LNC-2001 are often referred to as 2-step controllers, they are not true 2-step controllers. A 2-step has two distinct RPM limit functions with some method of enabling one RPM limit setting or the other. The LNC-2000 and the LNC-2001 have one RPM limit setting so if you are using either one as a launch control RPM limiter, you will need to use the factory ECM/PCM as the engine maximum RPM limiter engine speed governor. If you need a true 2-step, Lingenfelter Performance Engineering offers another module that has two separate RPM limiters, the LNC-003, but this device does not offer timing retard capabilities.

The RPM limiter function of the LNC-2000 and the LNC-2001 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 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 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.
