Ballenger Motorsports AFR500v3 Air Fuel Ratio Monitor Kit

A pro-grade wideband that's ready for HP Tuners out of the box. The Ballenger AFR500v3 is the current version of the AFR500 air-fuel monitor, preconfigured for vehicles tuned with HP Tuners software. Its linear 0-5 volt output feeds VCM Scanner through a PROLINK cable, or any other data logger or gauge.

Running methanol at low AFR? Ballenger recommends the NTK calibration-grade sensor; the production-grade sensor in this kit is the least expensive one they recommend for methanol. Need CAN output instead of analog? See the AFR500CANv3.
