These Holley Avenger EFI engine management systems are intended for users who want a bolt-on-and-go EFI system without the need for a laptop computer. The secret is the innovative Avenger EFI hand-held controller and the breakthrough technology of our self-tuning fueling strategies. The compact, easy-to-use controller guides you through the simple setup wizard, where you answer a few key questions about your engine setup. Once that basic information is loaded, you fire up the engine, run it through various rpm stages, and drive it to tuning perfection. The self-learning strategy will automatically tune your engine as you drive to deliver the optimum air/fuel ratios for performance and mileage.
