Overview

The Engine Control Module (ECM) is the brain of your late model GM fuel injected LS and LT engines. Chevrolet Performance engine controller kits are true stand alone systems that will get your project up and running with ease. These controllers are specifically calibrated for the engine and designed to be installed in older muscle cars and street rods. This means that all unnecessary electronic triggers and computer codes have been turned off to allow for maximum performance, pure calibrations, while still maintaining superior drivability and diagnostics. Most kits contain the following items; Oxygen Sensors, O2 Sensor Mounting Bosses, Mass Air Flow Meter (MAF), MAF Mounting Kit, Drive-By-Wire Throttle Pedal Assembly, Oil Pressure Sensor and Harness (NOTE: Some crate engines have the the sensor installed from the factory), Complete Engine/ECM Wiring Harness with a Fuse Box, Fuel Pump Power Module, Fuel Pressure Sensor Kit, GM Fully Calibrated ECM, Detailed Instruction Sheet.
