Evidently, DPF deletion takes about six hours to complete, but the real cash cow in all this is the software. Reprogramming the ECM to run at a much leaner mixture is crucial to this process and costs thousands of dollars. Most likely, his clients would engage a private shop to get their work done using the plates and gaskets that can also be ordered from this supplier, depending on what strategy is employed to defeat the soot burner and EGR cooler. Located in Vernon B.C., most of Jenner’s business is by mail order, it seems, with truck owners removing the ECMs from their trucks and shipping them to him by courier for reprogramming. The final step declared: “Kiss your downtime goodbye!”

He promptly e-mailed me a prospective work order and pricing for “several scenarios” as well as step-by-step instructions on how to remove the turbo and EGR cooler. “I can take you back to the good old days,” he assured me. “You and about four million other people!” he joked.

The president of J-Ball Electronics, Don Jenner, answered the phone himself when I called an 800-number listed on the above Web site, posing as the owner of a 2009 Peterbilt having problems with the DPF system. A simple search of the Internet turned up an online vendor in British Columbia who openly boasted, “SAVE UP TO 3 MPG!…We can eliminate the DPF-EGR from your Cat C7,C9, C13 or C15, Cummins ISB, ISC, ISL, ISX, Detroit DDEC 4&5 engines.” One garage in Montreal has a two-week waiting list and claims to process 20 rigs per day. With the addition of a straight pipe running through the gutted DPF canister, the modified tractors look almost identical to the ones coming from the factory.īeyond the reach of Environment Canada, and existing in the grey area of seemingly unregulated “aftermarket modifications,” the practice seems to have picked up steam in the last six months. Calling around, within half an hour, I found several independent garages in Ontario and Quebec that would remove and delete the EGR/DPF systems from almost any EPA-compliant engine.Įither by Internet or word of mouth, truck owners are attracted to shops and vendors that promise better fuel mileage, more horsepower and an end to expensive DPF maintenance bills. Although it is technically illegal to obstruct or dismantle pollution controls on trucks, the almost total lack of enforcement across Canadian jurisdictions has allowed some vendors to quickly fill this niche. With all the distrust over newer truck engines, it’s not entirely surprising that some owner/operators and small fleet owners might consider tampering with their exhaust gas recirculation (EGR) and diesel particulate filer (DPF) systems.īut what is surprising is how much of this is going on. As long as there have been pollution controls on engines, someone has tried to mess with them, either by removing, bypassing or modifying components.
