This is a product description of LT5 Crate Engine Control System Kit
This document provides installation instructions for the Chevrolet LT5 Crate Engine Control System Kit, Part Number 19370667. The kit is a standalone, fully-integrated system designed specifically for Chevrolet Performance LT5 series crate engines equipped with 58x crankshaft reluctor wheels, 4x camshaft indexing, and electronic throttle control. It is intended exclusively for use with manual transmissions and GEN 5 V8 engines, not earlier configurations.
The kit includes the Engine Control Module (ECM), Fuel Injector Control Module (FICM), Fuel Pump Power Module, engine harness, accelerator pedal, mass air flow (MAF) sensor, oxygen sensors, and various mounting hardware. Proper installation requires adherence to specific vehicle requirements, such as a vehicle speed signal of 40 pulses per revolution, tire diameters between 26 and 30 inches, and an axle ratio between 3.08 and 4.11. The guide details the mounting procedures for the ECM, accelerator pedal, and MAF sensor, along with critical system 'DOs and DON'Ts' to ensure safe and correct operation.
