For Those Who Need More - Know It - Control It

Improved Fuel Mileage - The AFR+ pays for itself by increasing fuel mileage
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.

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

Fuel Injection Control - Auto-Tune or Fuel Trimming
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 trimming operation 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.

AFR Gauge
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.

Wideband Controller - Bosch Chip and O2 Sensor
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 NAPA stores.

NOTE: Optional handlebar mount kit is black and can handle bars 7/8" to 1" in diameter.
