Range Technology™ was founded in 2010 by electronics engineers looking to provide simple to use solutions to Active Fuel Management (AFM) systems found in GM cars and trucks.  The goal was to offer inexpensive products that would not re-flash the factory ECU.  After hundreds of hours and thousands of miles testing, Range Technology™ is an industry leader and has expanded to offering multiple Active Fuel Management (AFM), Multi Displacement System (ADS) and Auto Start/Stop (ASS) products for late model GM, Chrysler, and Ford applications.  Racecar Engineering™ is proud to distribute and support the entire Range Technology™ product line.  Shop here online now for the most popular products from Range Technology™.  Always remember, if you don't find what you need on here our website, we'll gladly special order the item for you directly from the factory.  Please contact our Technical Sales staff for complete information.
