Overhead Control Module

The Overhead Control Module by Auto Rod Controls is a precision engine management component designed for serious vehicle builders and performance enthusiasts who demand reliable, centralized control over critical engine functions. This module serves as the command center for managing overhead systems, making it indispensable for custom engine builds, engine swaps, and vehicles requiring sophisticated electronic control architecture. Whether you're rebuilding a carbureted engine with modern EFI integration or fine-tuning a high-performance platform, the Overhead Control Module (model 8000R) provides the electronic foundation necessary to orchestrate complex overhead valve timing, fuel delivery sequencing, and ignition management from a single, strategically mounted unit.

Built with the durability and precision required in demanding automotive environments, this module features industrial-grade circuitry capable of handling the electrical load and thermal stress of continuous operation. The compact form factor—measuring 8.2 by 4.85 by 10.6 inches and weighing just 4.26 pounds—allows flexible installation in engine bays with space constraints, while the robust construction ensures reliable signal processing for fuel injector timing, ignition advance curves, and sensor feedback integration. Auto Rod Controls engineered this unit to minimize voltage drop and signal noise, critical factors when managing microsecond-precision fuel injection events and ignition timing on high-RPM builds where even millisecond delays compromise performance and drivability.

This module benefits engine builders, restoration specialists, and performance tuners working on vintage-to-modern engine conversions, turbocharged platforms, or carbureted-to-fuel-injected retrofits. Installation requires proper wiring harness integration and sensor calibration to your specific engine configuration; compatibility depends on your control system architecture and ECU specifications. Mechanics familiar with standalone engine management systems or modern OEM electronic controls will recognize the Overhead Control Module's role as the bridge between traditional mechanical engine operation and fully sequential fuel and ignition management, making it essential for any serious performance or restoration project.
