Coming Soon: Optimizing Performance with Cummins PowerSpec 5.4

PowerSpec 5.4, to be released later this year, includes several updates that will help you get the right gearing and parameter settings for every engine and every duty cycle.

Reporting has been improved with more accurate calculations and new graphics that make it easier to view engine duty cycles. Trip reporting now includes average engine load while in drive, and overall engine life totals. These reports can be saved in XML format for Microsoft® Excel, and exported to your designated folder automatically. Customizable parameters now let you adjust the idle shutdown timer when the parking brake is set, and adjust the numerical rate for the Sudden Deceleration function. PowerSpec 5.4 is backward-compatible, using the industry-standard J1939 connector as well as the J1708 connector. You can even use PowerSpec 5.4 to license your QuickCheck 5200 handheld diagnostic device.

But the new feature that will really make your life easier is “Easy Spec,” a wizard that makes it easy to set up an individual vehicle or fleet of trucks for maximum fuel economy. You just enter the following three pieces of information:

  • Maximum accelerator vehicle speed
  • Maximum cruise control speed
  • Idle shutdown timer

Then use the Performance Gauge to specify whether your customers want to maximize fuel economy or go for a balance between fuel economy and performance. Easy Spec will automatically show the default and calculated values that will maximize fuel economy and reduce operating costs.

Of course, Cummins PowerSpec 5.4 will continue to show you gearing recommendations. PowerSpec 5.4 will be available for download from by the end of this year. Watch your service publications for notification of its availability.
