MODULE KIT

The GM Performance 19354342 is an EFI engine controller kit specifically engineered for the LSX 454 engine. This complete control system includes the ECM, wiring harness, mass air flow (MAF) meter, MAF boss, accelerator pedal assembly, and two oxygen sensors with corresponding bosses, providing a streamlined solution for managing high-performance crate engine setups.

Designed for custom installations and engine swaps, this controller kit ensures precise fuel and spark management for the LSX 454. It is calibrated for use with an automatic transmission, supporting complex EFI requirements in various vehicle platforms where the LSX 454 is integrated.

Installation requires professional automotive knowledge, particularly in wiring harness routing and sensor calibration. It is essential to ensure that all factory harness connections are secure and that oxygen sensors are placed according to the included instructions to maintain optimal engine performance. Reuse of any additional vehicle-specific brackets or cooling components may be necessary depending on the chassis configuration.

This kit is inherently versatile, serving as a critical component for engine conversions rather than a replacement part for a specific vehicle model. Its compatibility is tied to the LSX 454 engine platform and automatic transmission setups; therefore, it will not fit applications utilizing other engine architectures or manual transmissions without significant modifications or re-calibration.
