This calibrated controller kit from Chevrolet Performanceenables the quicker and easier adaptation of GM's popular5.3L V-8 for countless hot rod projects. It works with 2005-2009 5.3L engines and is specially programmed for retrofitinstallations, with features that make getting the vehiclerunning easier than if a production 5.3L controller were used.The kit also includes hardware and components that don'ttypically come with used engines, such as the wiring harness,mass airflow meter and electronic throttle pedal - eliminatingthe need to source them separately.
Unlike the calibration for regular-production controllers, thisspecially calibrated 5.3L controller does not engage thecylinder-deactivating Active Fuel Management system thatoriginally came with the engines. A number of other featuresassociated with production-model systems are turned off withthe controller, as well, eliminating the possibility of "troublecodes" being set. It is also programmed for easy use withautomatic transmissions and includes a SES (service enginesoon) LED indicator embedded in the fuse box.
This 5.3L controller system is a true stand-alone system for usein older vehicles, as all that's needed to get a vehicle runningwith it are power and ground sources, a 58-psi (400 kPa) fuelpump and an electric cooling fan.
