    The AFR+ can handle ALL your fueling needs or COMPLIMENT ECU downloads or already installed EFI controllers. The AFR gauge allows you to KNOW exactly how well your tune-up is performing. The EFI fueling allows you to CONTROL any necessary fine tuning without spending more money or valuable time.

    BETTER FUEL MILEAGE - The AFR+ pays for itself! SAVING YOU $$$
    The information the AFR gauge displays is all you need to get the best fuel mileage out of your vehicle. The AFR+ can be used alone or in combination with your existing fuel controller or mapping software. With a low retail cost, the AFR+ can pay for itself in ONLY 3500 miles.

    The AFR+ allows your vehicle to be optimized to get the best horsepower and torque for the current modifications. 

    The AFR+ has built in a piggy-back EFI control system. A piggy-back EFI control system is one where it does not replace the stock ECU, but rather monitors the signals to the injectors and makes fuel adjustments based on the mode settings. The AFR+ can be computer programmed into an auto-tune or a fuel trimmingoperation mode. The auto-tune mode instantly makes adjustments to the fuel curve based on the wideband O2 sensor input to match the user's desired AFR value. The fuel trimming mode allows a user to make instant changes to the duration of time the fuel injectors are fired. The AFR+ features a push button interface on the gauge allowing for quick fine tuning by the end user for each operation mode.

    The AFR gauge provides the user an analog view of air/fuel ratio values between 10 and 16. The AFR gauge is the standard size of 2-1/16 inches in diameter to allow for multiple 3rd party mounting systems to be used. A self-adjusting back lighting display allows the AFR values to clearly be visible for both daytime and nightime riding.

    The wideband controller for the AFR+ uses a Bosch microcontroller for interpretating the data from the wideband Bosch O2 sensor. The AFR+ uses the Bosch O2 sensor part number 17018 and can be found at most local auto parts stores.
