The company grew from Western’s experience in Formula 1, Indy car, and engine-management development. After completing a master’s degree in engineering at Cranfield University in England, Western worked at Cosworth Engineering and later joined Michael Andretti’s Indy car operation in California before establishing EFI Technology.\n\nThe company’s original focus was programmable electronic control for racing engines. Its first fully user-programmable engine control unit, introduced in 1988, was adopted by Pontiac Motorsports for an IMSA racing program. Early racing work established EFI Technology as a specialist supplier able to combine engine-control hardware, ignition management, software, and calibration support for demanding competition environments. The business subsequently broadened its systems for automotive, off-road, marine, and motorcycle applications.\n\nA major early relationship was formed with Toyota Racing Development in 1990, when EFI Technology developed an ECU for Toyota’s 503E engine program. The engine powered All American Racers’ Eagle MkIII in IMSA GTP competition, where it achieved a highly successful record that included 21 wins from 27 entries and 14 consecutive IMSA victories. EFI Technology later supplied additional systems for Toyota Atlantic, SCORE off-road, and stadium-truck programs. The company also entered Indy car racing during the early 1990s, supporting Buick-powered programs. In 1992, Al Unser Sr. drove a Team Menard Buick-powered Lola to third place at the Indianapolis 500, then the best result achieved by the Buick Indy engine.\n\nEFI Technology expanded beyond competition vehicles during the 1990s. In 1995 it began designing systems for military applications, initially creating an ECU for a high-output endurance V8 used by the Naval Special Warfare Development Group. This work led to further defense and aerospace programs, including engine controllers and software for high-altitude unmanned aerial vehicles. The company later became a supplier to Elbit Systems, supporting UAV-related work associated with the Watchkeeper WK450 program for the British Army.\n\nThe company continued to develop international motorsport relationships. From 1996 it worked with Neil Brown Engineering on Mugen-Honda touring-car and Formula 3 engine programs. The Formula 3 program reportedly won ten consecutive championships from 1996 through 2005, while the touring-car program recorded 13 podium finishes in 1997. EFI Technology also supplied electronics for Nissan’s Infiniti V8 program in the Indy Racing League, using a system with self-learning lambda control intended to simplify tuning and improve engine performance. Later work with Mugen included controllers and ignition systems for NSX and MF408S V8 engines, with the latter appearing in American Le Mans Series competition in 2002.\n\nData acquisition became another important business area. EFI Technology introduced its data-acquisition product line in 2001, initially working with Team Fernandez in CART and subsequently adding Chip Ganassi Racing. The range expanded to data loggers and dash displays used in sports-car and open-wheel racing. Mugen also adopted and distributed some of these products for its JGTC program.\n\nSince 2007, EFI Technology has manufactured ECU and ignition products for Edelbrock, marketed under the Pro-Flo and Pro-Flo XT brands. The relationship later extended into data acquisition, including Edelbrock’s QD2 advanced data logger introduced in 2009. EFI Technology’s product history also includes systems for drag racing, motorcycles, midget and sprint cars, throttle-body injection, sportsman racing, and aerospace applications.\n\nEFI Technology’s positioning is that of a specialized engineering and systems supplier rather than a mass-market vehicle-electronics brand.

The company’s first major product was a fully user-programmable ECU introduced for motorsport and adopted by Pontiac Motorsports in IMSA competition. This early success gave EFI Technology a foundation for supplying engine manufacturers and racing teams with configurable electronic control systems.\n\nDuring the early 1990s, EFI Technology expanded its racing portfolio. In 1990 it developed an ECU for Toyota Racing Development’s 503E engine program. The engine achieved notable success in IMSA GTP competition in the Eagle MkIII, including 21 wins from 27 races and a reported 14-race winning streak. EFI Technology subsequently developed products for Toyota Atlantic, SCORE off-road, and stadium-truck programs. The company entered Indy car racing in 1991 through programs using the Buick Indy engine. Team Menard’s Buick-powered Lola, driven by Al Unser Sr., finished third at the 1992 Indianapolis 500, which was described as the best Indianapolis 500 result for the Buick engine.\n\nIn 1995, EFI Technology diversified into military electronics. Its initial defense product was an ECU for a high-output endurance V8 used by the Naval Special Warfare Development Group. The company then pursued additional defense and aerospace applications, eventually specializing in engine-management systems for high-altitude unmanned aerial vehicles. This expansion broadened the company’s role from racing supplier to provider of specialized control electronics for mission-critical platforms.\n\nThe company developed a substantial European and Japanese motorsport presence during the second half of the 1990s. In 1996 it began working with Neil Brown Engineering, which represented Mugen-Honda engine programs in British touring cars and Formula 3. EFI Technology supplied electronics for a Formula 3 program that achieved ten consecutive championships from 1996 to 2005, as well as a touring-car program that recorded 13 podium finishes in 1997. In 1997, Nissan used EFI Technology’s latest 2.5-series ECU and CD ignition system for its Infiniti 4.0-liter V8 Indy Racing League program. The system incorporated a self-learning lambda strategy and was later adopted by teams using the Aurora engine.\n\nEFI Technology continued its Mugen relationship in 1999, developing an engine controller and ignition system for Mugen’s NSX program. Mugen later used related systems for its MF408S V8, which debuted at the 2002 Sebring 12-hour American Le Mans Series event. In 2001, EFI Technology introduced a dedicated data-acquisition product line. The company initially supplied Team Fernandez in CART and later added Chip Ganassi Racing. Its data loggers and dash displays also found use in Mugen’s Japanese sports-car activities.\n\nFrom 2007 onward, EFI Technology manufactured ECU and ignition products for Edelbrock under the Pro-Flo and Pro-Flo XT names. The commercial success of this arrangement encouraged EFI Technology to extend its work into data acquisition, and Edelbrock introduced the QD2 advanced data logger in 2009. EFI Technology’s product chronology shows continuing development of specialized ECUs and ignition products for drag racing, motorcycles, midget and sprint cars, throttle-body injection, sportsman racing, and aerospace.\n\nThe company’s later defense activity included supplying Elbit Systems with engine controllers and custom software for unmanned aerial vehicles. Elbit’s United Kingdom operation was associated with development of the Watchkeeper WK450 for the British Army, using an engine controller designed by EFI Technology.
