Designed for serious enthusiasts and professional tuners who demand real-time engine management and precision calibration, this lightweight variant addresses the critical need for responsive fuel delivery, ignition timing, and boost control without adding unnecessary weight to your platform. Whether you're building a dedicated track vehicle, a street-strip hybrid, or managing complex forced induction, the Dominator V5 delivers the capability professional engine builders and certified technicians have relied on for years.
The lightweight construction of this ECU variant—weighing just 4.85 lbs—proves essential in weight-sensitive applications where every pound impacts acceleration and handling. The compact footprint of 8.5 x 4.5 x 17 inches allows flexible mounting in engine bays with spatial constraints common in retrofit and competition builds. Holley's proven architecture supports unlimited fuel and ignition tables, sequential multi-point fuel injection control, and advanced data logging for dyno tuning and street validation. The red finish identifies this unit at a glance and provides heat-reflective properties that protect internal circuitry in high-temperature underhood environments typical of turbocharged and supercharged applications.
This ECU suits engine builders, performance shops, and dedicated hobbyists running carbureted-to-fuel-injected conversions, engine swaps, or stock vehicle tuning programs. Professionals familiar with Holley's software suite and wiring harness ecosystem will recognize the Dominator V5 as a direct integration point requiring standard automotive electrical practices and proper fuel system setup. Installation demands competent tuning knowledge or partnering with a certified Holley technician to unlock full potential and ensure emissions compliance where applicable. The lightweight red unit is ideal for motorsports competitors and street performance enthusiasts seeking maximum control with minimal installation burden.
