We bought our
Kenworth 2011 T800 with a Caterpillar C13 ACERT engine
as a certified pre owned rig. We got it from a large
in-state dealer with a great reputation. When we put
inservice on one of the oil fields, we had almost
immediate problems with EGR valves and a clogged DPF
filter.
We learned that our application which requires almost 24
-7 idle and slow speed operation was the cause of our
problem. Two times we brought is back to the dealer.
Both times they for a regen on the truck with their
computer. Still the problems came back.
We asked another vendor on the job site if they were
having the same problem. They told us that they used to
have big problems but ECMperformance was able to tune
their ECM. This got rid of all EGR and DPF issues for
our high idle application.
We were initially skeptical, but we figured we had
nothing to lose since the truck wasn't running right
anyway. ECMperformance had us ship the ECM to them. We
had it back in the truck 3 days later. Works really good
now. No more EGR or DPF problems. Idles all day and
night without a problem. Thanks!
