Oxygen sensors, also known as Lambda sensors or O2 sensors, are among the most sensitive and critical components on your car's engine. They monitor the air/fuel mixture under idle, moderate acceleration, and cruise conditions. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio than the newer wide range air/fuel sensors (A/F sensors). Today's engines may use as many as four oxygen sensors to monitor exhaust gas oxygen content and catalytic converter efficiency. In order to perform these functions properly, Denso oxygen sensors adhere to strict OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt drivability and illuminate the check engine light, resulting in costly and time-consuming repairs. Denso First Time Fit oxygen sensors are designed to meet those tolerances and more. Key features and benefits of Denso Oxygen Sensors include: * Robotic laser welds * Porous PTFE filters block efficiency-robbing contaminants * Double-protection covers maintain proper temperature for quicker response times and protect ceramic elements from silicone and lead fouling * Rugged, watertight stainless steel housings resist corrosion and contamination * Aluminum oxide trap layers keep silicone and lead out, preventing damage to the platinum electrode * Refined zirconia elements improves sensor response * Superior design maximizes engine performance while reducing fuel consumption and harmful emissions * First Time Fit design delivers the right part the first time

Denso air/fuel ratio sensors (A/F sensors) were developed to measure air-to-fuel ratios under a wider range of driving conditions than oxygen sensors. A/F sensors, also known as wide-band oxygen sensors, send information to the engine management computer to make adjustments based on driving conditions. Their wider range and variable adjustments allow engines to burn fuel more efficiently and produce fewer emissions. As A/F sensor technology has evolved, Denso has been there every step of the way. From the first thimble-type sensors to today's heated, quick-response sensors required to meet ever more stringent emissions regulations, Denso has supplied OEMs with quality components and continues to innovate. Denso helped to develop this important technology and you can rely on Denso First Time Fit A/F sensors. Features and benefits of Denso air/fuel ratio sensors include: * Tarnish-proof platinum electrode provides longer life and maintains accuracy * Quick-response planar zirconia element quickly detects oxygen concentration * Measures air/fuel ratios from approximately 12:1 to 19:1 * Increased performance by mapping air/fuel ratios throughout the RPM range * Lower emissions by optimizing the air/fuel mixture * Reduces fuel consumption and maximizes catalytic converter life * First Time Fit design delivers the right part the first time

For years, if you wanted to use your dyno's powerful data acquisition system to display and record air/fuel ratios, you had to piece together an external standalone air/fuel meter, along with a custom-made wiring harness to get a proper signal to record. Seeing the need for an easier way, FAST developed a plug-and-play kit that makes it easy for owners of any SuperFlow 902, AutoDyn, or CycleDyn dyno to measure their test engine's air/fuel ratio. FAST wideband O2 sensor kits for SuperFlow dynos include a wideband oxygen sensor and an O2 sensor processing unit that plugs directly into the AMP-style connector harness on the dyno. Once you configure the dyno's analog channel for the fuel you're using, the dyno will begin to display and record the air/fuel ratio. Making it easy to use was a priority for FAST, so these sensor kits utilize fully automatic sensor calibration. No need to manually "free-air" calibrate the sensor; just turn the power on, and in just seconds these FAST units output an accurate and consistent air/fuel signal. Additionally, each sensor kit is a standalone unit—so using multiple kits for measuring all your engine's cylinders is a breeze. With industry leading plug-and-play installation, accuracy, and ease of use, it's clear that FAST wideband O2 sensor kits for SuperFlow dynos are the best choice for serious engine tuners.
