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.
