<h3>FAST (Fuel Air Spark Technology): The Science Behind the Speed</h3><p><strong>FAST</strong> — short for Fuel Air Spark Technology — has earned its reputation as one of the most innovative names in performance aftermarket electronics since the 1990s. Since the 1990s, FAST has been recognized as the industry-leading developer of aftermarket electronic fuel injection technology, with engineers releasing innovative products year after year, driving growth in the aftermarket EFI marketplace.</p><p>In 2001, FAST became a member of the COMP Performance Group, allowing the company to conduct even more extensive R&amp;D with a larger team of engineers. This enabled the fuel injection innovator to conduct more extensive R&amp;D efforts with a larger team of engineers, which ultimately led to even more discoveries in computer-controlled horsepower. Today, FAST is a proud member of the Edelbrock Group family of brands — including Edelbrock, COMP Cams, TCI Automotive, Russell Performance, and Lunati Power — representing over 130 years of performance.</p><p>Headquartered in Olive Branch, Mississippi, FAST is committed to bringing the best fuel injection experience to racers and street enthusiasts worldwide. What sets FAST apart from the competition is its in-house approach to development: with a complete line of superior, easy-to-use EFI systems, intake manifolds, ignition systems, and other EFI components, FAST is committed to bringing the best fuel injection experience to both racers and street enthusiasts everywhere.</p><h3>Ignition That Commands Control</h3><p>At the heart of any high-performance engine management strategy is precise ignition control. FAST's <a href="/263-fast-ignition-control-module-10488">ignition control modules</a> are engineered to work seamlessly within their broader EFI ecosystem, giving tuners and racers exact command over spark timing. FAST offers a full range of ignition products including ignition systems, ignition timing controls, coils, spark plug wires, crank triggers, and distributors — spanning everything from XDi Street HEI to XDi Pro Race applications.</p><h3>Know Your Tune with Air/Fuel Monitoring</h3><p>Understanding what&apos;s happening inside your engine is critical to maximizing power and protecting your investment. FAST&apos;s <a href="/263-fast-air-fuel-ratio-gauge-16851">air/fuel ratio gauges</a> give enthusiasts real-time insight into their engine&apos;s fuel mixture. The FAST Wireless Air/Fuel Meters use an under-hood mounted Bluetooth module connected to oxygen sensors in one or both exhaust outlets, and FAST has revolutionized the tuning industry with the most advanced, app-based, wireless air/fuel meters in both dual and single sensor options.
