Software Is Now Available for Improved Cold Starting Capability {7620}
- Agricultural Tractors:
- Challenger 65E (S/N: 6GS1-UP; 1GM1-UP)
- Challenger 75E (S/N: 6HS1-UP; 1HM1-UP)
A change has been made to the engine software for the Challenger 65E and the Challenger 75E Agricultural Tractors. The cold start strategy has been improved. The earlier software in some cases could cause excessive smoke and rough running when the engine is started in cold temperatures.
The improved software is effective with Challenger 65E (S/N: 6GS930; 1GM219) and Challenger 75E (S/N: 6HS909; 1HM604). The new flash files are a direct replacement for the former flash files. The new flash files are available through normal channels.
