The days of relying on Dyno are over. Visualizing air/fuel ratio (AFR) data, in real-world driving situations, is the new standard. The AFR+ brings together two technologies in a single system to make it the most powerful and user-friendly adjustment device on the market. AFR+ combines an EFI controller with a wideband O2 sensor and AFR gauge to provide the user with instant fuel reduction capability and provide feedback on their vehicle's tuning status on the Analog Values View of the air/fuel ratio between 10 and 16. The AFR gauge information displays are also all you need to get the best fuel mileage from your vehicle. The AFR+ has integrated a piggyback EFI control system that does not replace the stock ECU, but rather monitors signals sent to the injectors and makes fuel adjustments based on mode settings. The AFR+ can be programmed in auto-tuning mode or fuel reduction operating mode. Autotune mode instantly makes adjustments to the fuel curve based on wideband O2 sensor input to match the user's desired AFR value. Fuel reduction mode allows a user to instantly change the run time of the fuel injectors. The AFR+ features a push-button interface on the gauge allowing for quick and precise end-user adjustment for each operating mode. The AFR gauge measures 2 1/16" (52 mm) in diameter to allow use of multiple third-party mounting systems. A self-adjusting backlit display allows AFR values to be clearly visible for day or night driving .
