In 1986, the GM Motorsports group asked Delco Electronics Corporation (December), a subsidiary of GM Hughes Electronics (headquarters- Kokomo, Indiana) if an electronic engine management system could be developed for the Chevy Indy V8 engines used in the CART open-wheel race series. Delco Electronics had been supplying all GM automobiles sold in the US with Engine Control Modules (ECMs) since 1981 when the US Clean Air Act required 3-way catalytic converters and controlled air-fuel ratios. The production ECMs were becoming more complex, and were becoming powertrain controllers controlling the transmission, spark timing, Idle speed, as well as air-fuel intake mixtures.
Delco Electronics hired a small group of electronic designers and technicians at their facility in Goleta, California (near Santa Barbara, California) to undertake special assignable projects that were advanced or more state of the art. This facility was called Delco Systems Operations (formerly known as GM Defense Research Labs), a part of Delco Electronics Corporation at the time. Delco Systems Operations is the place where the Apollo Program's Lunar Rover Mobility Sub-system[1] was developed and built, also the Apollo Program's guidance computers (Apollo PGNCS) and the Boeing 747 guidance computers (Delco Carousel IV) were developed and manufactured there. All Delco Electronics Motorsports products developed before 1994 were designed by this group. From 1994 onwards, they have been developed at Delco Electronics/Delphi in Kokomo, IN.
The first generation of engine management controller for CART racing used a modified production ECM, but performed poorly in the race car due to the harsh EMI (Electromagnetic Interference) environment. This version was never used in racing, but the experience gained enabled the engineers to design a more successful Generation 2 controller for use in the 1988 CART IndyCar World series.
Generation 2 controllers were used experimentally by Newman/Haas Racing in 1988 and the first win was in the Cleveland GP with Mario Andretti driving.
In 1989 Newman/Haas Racing, Team Penske, Galles Racing, and Patrick Racing teams used Delco Electronics Gen-2 controllers with the Ilmor Chevy Indy V8 engine. "By the start of the 1989 season, racing pundits recognized that Chevrolet, with its Ilmor Engineering engines and Delco Electronics equipment, had assembled perhaps the most potent racing power in the history of the sport. As the season got under way in April, the pattern of winning began. Racing's elite drivers- Al Unser Jr. and Senior, Emerson Fittipaldi, Rick Mears, Danny Sullivan, and Mario and Michael Andretti—were driving the best equipment in the world.
The results began to show early on. By October, Chevy engines with DE equipment had won 13 of the 15 IndyCar races.
When Emerson Fittipaldi won the 1989 Indianapolis 500 in a Chevrolet Indy V8 engine controlled by a Delco Electronics electronic engine control module (ECM), it was the first time in the 500's history that the engine of the winning vehicle was controlled by an electronic engine management system.[2]
For the 1990 season, all teams using the Ilmor Chevy Indy V8 were provided a redesigned Gen-3 system and it won 15 poles, 16 wins including the 1990 Indianapolis 500, with 17 races in the IndyCar World Series. To prove the system, the components were used with GM engines in the Trans-Am Racing series during 1989.
In the 1991 IndyCar World Series, Gen-3 had a perfect score: 17 poles, 17 wins, 17 races including the 1991 Indianapolis 500. At the 1991 Indianapolis 500, Delco Electronics introduced telemetry to the electronic system using the advanced spread spectrum radio technology.[3] It was so popular that all IndyCar teams eventually used it, and many still use it. ABC TV used the data from the systems to display real time data with ABC's in-car video cameras.
In 1990 and 1991, the Chevy engine with the Delco Electronics Gen-3 controller won 33 straight IndyCar races. Chevy's dominance had proved that electronics had found their place in IndyCar racing.
In the 1992 IndyCar World Series, race cars with Gen-3 captured 7 poles, 11 wins including the 1992 Indianapolis 500, in 16 races.
For the 1993 IndyCar World Series, Delco Electronics had been developing a smaller more powerful controller using 32-bit computers and a high-level software language called Modula-GM. This system was called Gen-4 and won much praise for its improved functions and features. The telemetry system developed for the 1992 season was used, and a new Distributor-less Ignition module component was added to the overall engine management system. 10 wins including the 1993 Indianapolis 500 in 16 CART races.
In 1994, a totally new Ilmor engine was introduced to IndyCar teams and the engine controller was Delco Electronics Gen-4: 12 wins including the 1994 Indianapolis 500, 16 races.
In 1995, Gen-4 won 6 races out of 17.
In 1996, the Indy Racing League split from CART and used the naturally aspirated Oldsmobile Aurora engine, which used the Delco Electronics Gen-4 system until the engine was retired from the IRL IndyCar Series a few years ago. 1997 was the last year the Gen-4 ran in the CART IndyCar World Series.
Per a February 27, 2003 Delphi Press Release,[4] Delphi's current involvement in open wheel racing is as follows:
"Delphi is the official electronics provider to the IRL and has been involved in open-wheel racing since 1988. Today, a majority of the vehicles in the IRL are equipped with several of Delphi's racing products including:
Delphi also has begun offering services to the racing industry, including Hydraulic Sled Testing from its state-of-the-art testing laboratory in Vandalia, Ohio. Delphi provides comprehensive safety testing using a hydraulic test sled to simulate a crash. Services include on-board data acquisition, on- and off-board digital video monitoring and the use of Delphi safety products such as the earpiece sensor system and accident data recorder."
