Detroit Diesel Corp. has announced it will soon make available to customers a free software release that the company said will enhance the fuel economy of EPA ’07 Series 60 engines by up to 2.5%.


"Extensive testing of the Series 60 has shown our particulate filter regeneration process is more effective than originally anticipated," said David Siler, director of marketing for Detroit Diesel. "The fact that the filters are staying clean, combined with some advancements in the regeneration software, allows us to enhance the regeneration process to improve the fuel efficiency for the engines."

Detroit Diesel also announced no-charge updates that it said can significantly enhance vehicle shifting and cruise control operations. According to the company, fleet owners and owner-operators can schedule a visit to any Detroit Diesel dealer or distributor to have their EPA ’07 Series 60 engine re-flashed free of charge beginning July 1, 2008. After that date, all EPA ’07 Series 60 produced will be automatically programmed for the modified regeneration cycle.
