About aRacer AF2 Professional Wideband AFR Module
aRacer's upgrade AF2 Wideband O2 AFR Module packs a lot of upgrades over their previous version, including a Bosch LSU 4.9 wideband O2 Sensor for more stable, accurate, and faster readings. They also improved the connection to their ECUs by providing a harness that plugs directly into their ECU without the need for extra converters or adapters, so the install is faster and easier and you can get back to riding.

If you have a Aracer Mini X this is a must have. You can’t run Autotune without it and you absolutely want to use Autotune. The AF2 with the mini X made the biggest difference on my bike than any other modification. And actually improved the other modifications I had already done. The AF2 arrived in 2 days. They were way faster than any other place I looked at to buy it. Aracer customer support sucks but MNNTHBX is the best.
