DBW Accelerator Pedal

The HOLLEY DBW Accelerator Pedal (model 145-160) is a drive-by-wire electronic throttle control system designed for custom engine builds and high-performance fuel-injected applications. This component replaces mechanical cable linkage with direct electronic signal transmission, providing enhanced control over fuel delivery timing and throttle response. It is particularly useful for those converting from carbureted to EFI systems or swapping engine platforms.

The DBW accelerator pedal operates via potentiometric sensing, where a variable resistor sends a proportional voltage signal to your ECU or stand-alone fuel injection controller. This design allows for real-time adjustments to fuel injectors and ignition timing as the pedal is depressed. HOLLEY has engineered this assembly with a compact footprint and lightweight construction to fit modern engine bays efficiently.

Engine builders and fabricators benefit from this pedal when integrating standalone fuel management systems like HOLLEY EFI or MegaSquirt. The pedal is factory calibrated for plug-and-play installation into most aftermarket ECU harnesses, making it a versatile choice for various performance applications.
