A precisely calibrated engine control module is essential to making yourfuel-injected LS engine perform in your older vehicle - and ChevroletPerformance is your source for controllers that are designed for easy, ''plug-and-play'' installation and, in most applications, no need for third-partytuning adjustments.
Unlike production controllers that may or may not come with a usedengine, our controllers are calibrated for installation in older vehicles. Thatmeans many of the features required for late-model production vehiclesare ''turned off'' because they're not required in older cars and trucks. Thatmeans features that may trigger a diagnostic trouble code and possiblyaffect performance - requiring additional tuning - are not enabled.Our inclusive kits deliver all the components required to plug into theengine and get it running - from the controller itself and the accompanyingwire harness to the mass airflow sensor, oxygen sensors and even athrottle pedal assembly for engines equipped with an electronic throttlebody. The kits also include detailed instructions to help you do it right thefirst time, even if you have no experience.

Each Chevrolet Performance controller kit is a true stand-alone system.All that's needed to get a vehicle running with it are power and groundsources, a high-pressure fuel pump and an electric cooling fan.
