For years, if you wanted to record air/fuel ratios with your in-car data acquisition system or your dyno’s recording software, you had to piece together an external, stand-alone 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™ engineers have developed a plug-and-play kit that makes it easy for anyone to measure their engine’s air/fuel ratio. The FAST™ kit includes a wide-band oxygen sensor and an Air/Fuel Ratio Module that wires directly into any data acquisition system. The FAST™ kit outputs a 0-1.5 volt signal that corresponds to your air/fuel ratio (Lambda). Compatible with gasoline, methanol, E85, E98 and diesel, the FAST™ Air/Fuel Ratio Module is ideal for any situation where tuning for maximum horsepower is desired. Making it easy-to-use was a priority for FAST™ engineers, so these sensor kits utilize fully automatic sensor calibration. No need to manually “free-air” calibrate the sensor; simply turn the power on and in just seconds, the FAST™ unit outputs 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 just that easy.

With industry leading plug-and-play installation, accuracy and ease of use, it’s clear the FAST™ Air/Fuel Ratio Module is the best choice for serious engine tuners
