GM Powered Solutions Debuts Smarter Engine Control Module for 6.6L Gas Engines

General Motors' new engine control module for 6.6-liter heavy-duty gas engines aims to simplify customization for commercial vehicle builders while ensuring reliability.

Marine propulsion heritage
over 100 years

What Happened

GM Powered Solutions (GMPS) is GM's unit providing propulsion systems for marine, industrial, off-road, and on-road commercial applications. It leverages GM's high-volume powertrain expertise to offer reliable, proven hardware that customers can tailor to their needs.

Main application areas
  • Reliable power for heavy- and medium-duty on/off-road fleets
  • Dependable marine propulsion for boat builders and OEMs
  • Tough, consistent performance for industrial equipment
New ECM vs Traditional Approach
Before
Customers reverse engineered ECMs to fit unique applications, a costly and time-consuming process
After
New ECM comes with GM-approved base calibration pre-loaded, ready-to-run, reducing development time and field issues

The new ECM is designed for 6.6-liter heavy-duty gas-powered engines used in on-road commercial vehicles. It is customizable for different jobs, from last-mile delivery to heavy construction, but with less development time and fewer surprises. Customers also benefit from GM's global Customer Care and Aftersales network for parts and service support.

Why this matters

Commercial vehicle builders often modify engines for specific jobs, which can be costly and complex. GM's new pre-calibrated control module reduces development time and errors, making it easier to get dependable power for tasks like construction or delivery.
