Technology testing using test track fuel efficiency evaluation procedures reveals lack of accuracy in engine Electronic Control Module data

PIT Group, a not-for-profit engineering and research group for the North American trucking industry, today announced the availability of a technical report comparing data on fuel consumption from engine Electronic Control Modules (ECM) with test track evaluations. The report details ECM data precision and accuracy between engine manufacturers, and among engine models from a single manufacturer.

“The ability to measure fuel consumption accurately and precisely and defend the results is critical for writing vehicle specifications, for establishing effective maintenance practices, and for training drivers to operate vehicles as fuel efficiently as possible,” said Yves Provencher, director of PIT Group. “Our tests show that engine ECMs present different levels of precision and accuracy, and that ECM data should be used with caution for evaluating the impact of a fuel saving technology or operational practice.”

The PIT Group study that compares engine ECM data with actual test track fuel consumption was conducted in the fall of 2014 on 14 different vehicles with engines from four manufacturers. The test track evaluations, which followed the Joint TMC/SAE Fuel Consumption Test Procedure Type II, compared fuel consumption data provided by the engine ECMs.
