BETTER HORSEPOWER and TORQUE
The AFR+ allows your vehicle to be optimized to get the best horsepower and torque for current and future modifications.
FUEL INJECTION CONTROL - AUTO-TUNE or FUEL TRIMMING
The AFR+ has a built-in piggy-back EFI control system. A piggy-back EFI control system is a system that does not replace the stock ECU, but monitors the signals to the injectors for the purpose of automatic 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 spraying fuel. 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 with 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 backlighting display allows the AFR values to clearly be visible for both daytime and nighttime riding.
WIDEBAND CONTROLLER - BOSCH CHIP and O2 SENSOR
The wideband controller for the AFR+ uses a Bosch microcontroller for interpreting 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.
