LNC-2014 Lingenfelter Adjustable RPM Limiter & Timing Retard Controller For GM Gen V Direct Injection V8 Engines LT4, LTI, L86, L83. 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-2014 can also be used to retard the timing to build more boost at the line.
LNC-2014 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 the same time. If the two dont completely cut fuel at the same time you will run lean when the one system cuts off the injectors, risking severe engine damage.
The RPM limiter function of the LNC-2014 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-2014 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-2014 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.
