TFI AFR+ Gen4 FXD06-11+F*ST07-11 Wht gge

The days of Dyno dependency are over. Air Fuel Ratio (AFR) data viewing, in real driving situations, is the new standard. The AFR+ brings together two technologies within one system to make it the most powerful, user-friendly tuning device on the market. AFR+ combines an EFI controller with a wideband O2 sensor and AFR gauge to provide a user instant fuel trimming ability and gives feedback about their vehicle's state of tune on the analog view of air/fuel ratio values between 10 and 16. The information the AFR gauge displays is also all you need to get the best fuel mileage out of your vehicle. The AFR+ has built in a piggy-back EFI control system which 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 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. The AFR gauge is 2 1/16" (52mm) in diameter to allow for multiple third party mounting systems to be used. A self-adjusting back lighting display allows the AFR values to be clearly visible for both daytime and nighttime riding.
