The sole reason of the truck's unreliability is the DPF Filter and a regeneration cycle that just doesn’t work in the real world.
Fort Lauderdale, FL (PRWEB) April 03, 2012
Ecm Performance provides Engine Control Module (ECM) programming and Diesel Particulate Filter (DPF) Deletion for Cummins ISB 6.7 & ISC 8.3, Paccar PX6 & PX8 DPF equipped diesel trucks like the Ford F650 - F750, Peterbilt, Freightliner, Kenworth, Sterling Trucks, Thomas Bus and more.
In real world work applications, these trucks are increasingly used as machines requiring long idle and extended use of PTO (Power Take Off) Mode. This prevents the truck from properly going into its regen cycle which is supposed to clean the DPF filter.
And this is where the trouble begins, as a clogged DPF filter can result in diesel soot backing up into the engine causing damage to the VGT actuator, turbo, fuel injectors and EGR solenoid. Also the unburned fuel injected into the exhaust system as part of the regen cycle can go into the crankcase contaminating the engine oil.
The most common Cummins DPF related symptoms that owner/operators experience are clogged and cracked DPF filters; high cleaning / replacement costs; lost income due to truck down time; excessive regeneration cycles; and reduced power / limp mode in PTO.
These DPF problems are so widespread that the first class action lawsuit has been filed on behalf the owners of Dodge/Cummins equipped vehicles. This case has yet to be settled or go to trial.
Jim Comack at ECM Performance says, “Lawsuits will never make these trucks run reliably. We can get any DPF equipped vehicle back to full reliability with our unique programming service and the customer simply removing their DPF filter.”
Ecm Performance technicians travel anywhere-anytime from China to Alaska and all points in between to reprogram the Cummins ECM's right on the vehicle. For fleet service and in-use time critical vehicles, this premium service will only take hours instead of days.
For remote service, customers simply unbolt it the ECM from the engine block and unplug the harness connections. They prepare their order at http://www.ecmperformance.com website. Typically, within 48 hours the ECM has been flashed to the customer’s specifications and returned via next day air, ready for reinstallation into the vehicle. Just bolt it back to the engine block and replug the harness connections.
At Ecm Performance, the original engine data is read from the ECM and backed up three ways for the customer’s protection. An ECM Performance technician then modifies the calibration to shut off the after treatment system / DPF cleaning cycle. Then the new calibration is flashed to the truck’s ECM resulting in 100% Code Free operation.
For ECM’s that have been modified to run off road or for export with DPF Deletion the customer must remember to remove the DPF and replace it with a straight pipe. Failure to do this could result in engine damage.
Scott P., a fuel delivery service in Green Bay, WI, said, “We have 4 2009 Peterbilt 335 Propane Tank trucks with Paccar PX8 engines. They each have about 65,000 miles. Between all the trucks, we spent over $25,000 in uncovered repair bills and towing charges all related to problems with the DPF. The only time the trucks ran right was the 40 mile drive back from the Cummins dealer. We were ready to take a loss and just sell the trucks. A friend of mine in the same business suggested we contact Ecm Performance. After Ecm Performance sent us back our reprogrammed ECM’s, our 4 trucks have been on the road all winter long earning money instead of costing us hard dollars out of our pocket.”
Jim Comack at ECM Performance said, “Scott’s experience with a Cummins DPF equipped truck is very typical. My heart really goes out to these guys. Most are just trying to make a living with trucks that just are not reliable. The sole reason of the unreliability is the DPF Filter and a regeneration cycle that just doesn’t work in the real world. It doesn’t matter how many times these guys tow their truck back to factory service facilities. The only way to restore full reliability is to shut off the Regen Cycle through reprogramming the ECM. They can then remove the DPF. Like magic all their DPF related problems disappear.”
