Ballenger Motorsports is presenting a limited time (until October 31, 2014), sponsorship discount only to FSAE & Formula Student teams for our AFR500 - Air Fuel Ratio Monitor Kit - Wideband O2 System ! The coupon code is 091514WJQF37 which takes $50 off the $299 wideband meter with sensor. Most teams will already be aware of the need for an excellent air fuel ratio measurement system and this particular one is well suited to use on a vehicle or dyno cell. Any team familiar with the NGK Powerdex AFX will find that this product has identical features & function. The AFR has an analog output for use with data logging systems and works with a variety of Bosch and NTK lambda sensors.
