WARNINGS:

The RPM limiter function of the LNC-003 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-003 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-003 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.

DO NOTplaceindirectexposuretoexhaustmanifolds,turbochargerturbinehousingsorotherunderhooditemsthatarehightemperatureheatsources(radiatedheatsources).Thewarrantydoesnotcoverdamageduetomeltedenclosuresorwiringduetoimproperinstallation.
