Fleets that optimize their electronic engine parameters for fuel economy can expect to see about a 0.5 mpg improvement in fuel economy, according to a Confidence Report by Trucking Efficiency, a project of the Carbon War Room and the North American Council for Freight Efficiency.
Fuel economy improvements of 5 percent to 8 percent are possible for fleets that previously have not used parameters to optimize for fuel economy.
According to the report, engine parameters add no weight or cost, and don’t require any additional maintenance; they are already a part of the engine control software.
The report offers insights and best practices to deal with the obstacles to programming and maintaining parameter settings. It also contains fleet and dealer perspectives on setting and using electronic engine parameters, a summary of service tools available from engine manufacturers and a parameter names comparison chart.
