Lingenfelter Performance Engineering (LPE) has announced the LNC-002 – an adjustable RPM limiter for General Motors LS series engines that provides consistent launch RPM off the line in drag racing and standing-start road racing applications. The LNC-002 also includes a Timing Retard function useful in turbocharged, supercharged and nitrous applications.
“Our latest launch controller is a functional, plug-and-play product designed specifically for today’s racers,” said Ken Lingenfelter, owner, Lingenfelter Performance Engineering. “The LNC-002 can be used as an adjustable, individual cylinder RPM limiter that provides fast-acting, spark-based engine RPM limit control. It also features a Timing Retard function that can retard timing by up to 15 degrees. The timing retard can be based off of manifold pressure for turbocharged and supercharged applications or can be time-based for nitrous oxide applications. It can also be used in combination with the launch control function off the line in drag racing to build additional boost in turbocharged applications.”
Featuring a custom-molded, high-temperature glass filled Nylon 6 enclosure, users have direct access to the launch controller settings without having to remove a cover or access panel. The product’s RPM limiter activation can be adjusted from 1,500 to 9,900 RPM in 100 RPM increments, and both ground activation and 12-volt activation inputs are provided for RPM limit activation.
Additional product benefits include a 40-MHz 16-bit automotive-qualified processor; dedicated timers on each coil drive circuit to keep timing accurate over the full RPM range; independent coil drives that provide Sequential Ignition Kill when RPM limiting is active; active clamps and optical isolation to suppress electrical noise; separate RPMx100, RPMx1000, Degrees and Rate switches for easy adjustment; and an analog voltage output wire to send timing retard information to data acquisition systems.
The LNC-002 (part number L460095297) is designed for use on all GM LS series engines – LS1, LS6, LS2, LS3, LS7, LQ4 and other Gen III/IV GM V8 applications – as well as GM V8 engines that use the same ignition coil system, including:
• 1997-2010 Corvette (2009-2010 ZR1 Corvette requires custom wiring)
• 1998-2002 LS1 V8-equipped Camaro and Firebird
• 2010-2011 Camaro SS
• 2004-2006 Pontiac GTO
• 2004-2007 Cadillac CTS-V
• 1999-2010 GM CK trucks, Tahoe, Yukon, Escalade, H2, Sierra, Silverado and Avalanche (with the 4.8L, 5.3L, 6.0L, 6.2L engines). It will not work on 305 and 350 Vortec engines.
• 2003-2006 Chevrolet SSR
• 2006-2008 Trailblazer SS and other S/T body trucks with 4.8L, 5.3L and 6.0L Gen III engines
A second version of the launch controller, the LNC-003 (part number L460105297), is also available and provides two separate adjustable RPM limits but does not provide a Timing Retard function.
The Lingenfelter Launch Controllers are prices right around $250 and are available as part of a complete kit including a shift light, RPM switch and MPH switch for around $450.
