Wideband AFR Data for Legacy and Current aRacer ECU Systems.
The aRacer AF2 Wideband AFR Module is an air-fuel ratio monitoring module designed for supported aRacer ECU systems, including many legacy and current aRacer ECU platforms.
What It Is
A wideband oxygen sensor module that allows compatible aRacer ECUs to monitor air-fuel ratio data for tuning, calibration, logging, and closed-loop fuel control.
What It Does
- Provides wideband air-fuel ratio monitoring
- Supports fuel tuning and calibration
- Supports legacy aRacer AutoTune functions where compatible
- Supports wideband O2 closed-loop fuel control on compatible ECU systems
- Works with many legacy and newer aRacer ECU platforms
- Useful for dyno tuning, track testing, and performance development
- Supports data logging and real-time AFR feedback where supported
- Designed for high-performance motorcycle, ATV, scooter, mini moto, and UTV applications
Compatibility
The AF2 Wideband AFR Module works with supported aRacer ECU systems, including Super 2, Mini 5, Mini 5 Plus2, RC1 Super, Super X, Super XX, Mini X, and Mini XX platforms where compatible.
The AF2 supports legacy AutoTune functions and fully functional wideband O2 closed-loop fuel control on compatible models.
Important Note
The AF2 does not support AI AutoTune and does not have the same high-speed enhanced-resolution wideband O2 capability required for AutoTune Pro. For AutoTune Pro and enhanced high-speed wideband support, use the aRacer AF3 Wideband AFR Module where compatible.
