Kenworth ECM Programming
Kenworth's modern fleet population runs primarily on Paccar MX-13 and Paccar MX-11 engines, with Cummins X15 / ISX heritage across older highway and vocational equipment. The full Kenworth lineup — T680 fleet long-haul, T880 severe-duty vocational, W990 owner-operator long-haul, the W900 classic, plus medium-duty T370/T380/T480 — is programming work we do every week.
Highway
Kenworth's highway lineup runs from the modern T680 fleet long-haul tractor through the T660 legacy fleet workhorse to the W900 classic and W990 premium owner-operator platforms.
