Description
The aRacer AF1 is a high speed AFR module that can be used for live autotuning or as a tool for dyno tuning. It includes a high quality Bosch wide band O2 sensor and plugs directly into the expansion port of the aRacer Speedtek RC2 Super or Mini 5 ECU.
If purchased with an RC2 Super ECU, we can preload your ECU with our proprietary autotuning race settings, or provide them to you to upload into your ECU via iLink cable.
