Ballenger Motorsports AFR500 Tuning Manual
The Ballenger Motorsports AFR500 is a precision oxygen concentration measurement system utilizing wideband technology to sense air-fuel ratios in the range of 9.00:1 to 16.00:1. Unlike conventional sensors, it uses a pumping current controller to estimate the ratio rather than outputting a direct voltage signal. The kit includes the AFR500 controller, a Bosch LSU 4.2 or NTK wideband oxygen sensor, a wiring harness, and a tuning manual.
