Cases By Region

Drove 18 hours into hurricane-stricken Florida with three bucket trucks for emergency power restoration. One truck went into shutdown within days; the other two went into limp mode within a week with PTO failures during sustained bucket operation. Without these trucks operating, the storm-relief contract — and the payday — was at risk.

Called ECM Performance at 4:30 PM. Technician drove four hours overnight and arrived before sunrise. Coordinating with off-site team, all three trucks were running perfectly by 2 PM the next day. Three weeks of zero limp-mode, PTO, or shutdown events followed. Storm restoration completed; full payday earned.

Of 40 vehicles in the construction waste fleet, the 2007–2009 DPF-equipped trucks were the only ones with problems. Constant regen, power de-rate, recurring check-engine codes. Dealer-replaced turbos, EGRs, DPF filters, and DOCs across multiple trucks without resolving the underlying issue. Money pit.

Started with one ECM as a test — back in two days, truck now runs better than the day it was bought. Sent the remaining fleet ECMs one at a time. All reprogrammed trucks are back on the jobsite producing revenue.

Nine Peterbilt 340 concrete mixers constantly in regen and breaking down. Trucks shut down in PTO, couldn't idle, and went into limp mode mid-pour. Forced to dump full loads of cement when trucks failed in transit. Dealer service couldn't resolve the recurring pattern.

Started with two ECMs — back in two days. Six weeks later, zero recurrences. Working through the rest of the fleet one at a time.

Fleet of Freightliner M2s with DPF were shutting down on the open road in sub-zero weather. Dealer said nothing was wrong. Routinely towing our own trucks during the plow window — when the money is made.

Shipped one ECM via FedEx, back in 48 hours. Two weeks of flawless operation. Now sending the rest of the fleet ECMs in sequence.

Heavy idling and PTO duty produced constant DPF problems despite under 20,000 miles per truck. Limp mode, shutdowns, impossible to haul reliably.

ECM Performance resolved the DPF pattern across the fleet with fast turnaround.

Truck sitting idle through Minnesota winters because the DPF system couldn't handle cold-weather vocational duty. Started with one ECM in November 2012; came back to a working truck for the first time in years.

Second ECM programmed in two days — sent Wednesday, back Friday morning. First winter ever the fleet ran without DPF-related problems.

Constant regen cycles even on highway-cycle operation. Four regen events on a single 500-mile trip. Hard to shift during regen, shaking, backfiring, foul exhaust. Check-engine lights and periodic white smoke. Dealer dead-end.

ECM Performance addressed the underlying calibration pattern. No more engine lights, no constant regen, no white smoke.

Limping, constant regen, repeated shutdowns. Couldn't feed the herd without fighting the truck. Followed customer testimonials from the ECM Performance email updates for eight months before finally sending in the ECM.

Got the ECM back in two days, reinstalled, removed the DPF. Truck works great. PTO for the feeder works without a hitch.

Constant regen cycles, power de-rates, and recurring fault codes for DPF / crankcase pressure (codes 0555, 1881, 1883). Replacing the crankcase filter every 100+ hours to clear errors. Unburned regen fuel pushing past piston rings into crankcase — classic pattern for service-truck duty cycle.

Reprogrammed ECM + DPF removal. Like magic, no more codes or problems. Wish we'd known a year ago.

Only 1,700 hours but constant DPF-related limp modes. Cummins Insite forced regens at the dealer held for 15-18 hours before relapsing. PTO duty cycle fought the calibration. Older 2006-and-earlier trucks with no DPF had no problems.

ECM shipped, returned in two days. 100+ hours of trouble-free operation since.

Low-speed sweeper and refuse duty cycle fought the aftertreatment calibration. Constant regen and limp mode. Manufacturer, dealer, and Cummins service all said 'nothing is wrong' — the trucks just couldn't operate at 40 mph to sweep streets or pick up trash.

Both ECMs reprogrammed. Back to full-time operation, no outside contractor needed.

Second ECM sent to ECM Performance after the first repair held up. T-300 in limp mode, no boost pressure on acceleration, recurring red and amber check-engine lights.

Lightning-fast turnaround. T-300 now running as great as the Peterbilt 340 from the previous order.

Recurring engine problems even after the dealer kept the truck for two weeks at a $3,500 cost. Truck ran for three days, then started flashing engine problems again. Barely running by week's end.

Overnighted ECM. ECM Performance did in two days what the dealer couldn't do in two weeks — or two years.

Constant slow-speed and idle operation prevented DPF from completing regen. Truck shut down unexpectedly and had to be towed to the dealer with no permanent fix.

ECM programmed, returned in two days. No more problems. Fuel economy went from 8-9 mpg to 14 mpg — the reprogramming pays for itself in fuel savings.

Constant limp mode from dirty DPF. Removed the DPF first without reprogramming the ECM — truck ran great briefly, then stopped running flat. Cummins dealer pointed to ECM Performance for the calibration work.

ECM back in a few days. Plugged back in, truck fired right up and runs great.

DPF problems across F-450 and F-550 fleet drove the decision to proactively program the low-mileage F-650 before issues arose. Removed DPF ceramics, reattached empty canister.

Overnighted ECM, took 20 minutes to remove and reinstall. One missed connector caused a check engine light; ECM Performance support diagnosed it via blink-code pattern. Power and torque increase noticeable.

In two years of ownership: DPF filter replaced, plus injectors, turbo, EGR cooler — all DPF-driven. Worried about post-warranty reliability for long hauls. When the DPF was finally removed, the ceramic elements were cracked and crumbling; catalytic converter elements melted.

ECM Performance reprogrammed. With DPF removed, truck now runs better than ever and can run long hauls confidently.

Six months in: urea line contamination, exhaust sensors, DPF filter replacement. Truck spent half its life at Ford and Cummins dealers without improvement. Truck drove fine home, then went back into limp mode within days. Threatening the municipal service contract.

ECM reprogrammed, DPF replaced with straight pipe. Truck now runs without any code or limp mode for the first time since purchase.

Constant idle and slow-speed operation on construction sites. Replaced turbo, VGT actuator, two DPF filters across dozens of dealer visits over 140,000 miles. Shutdown, reduced power, never running properly.

ECM shipped, returned in three days. Truck now runs better than the day it was bought — better than brand new.

Replaced turbo and DPF filter. Couldn't idle, recurring shutdowns, limp mode every few days. Service tech directly identified the DPF filter as the source and recommended ECM Performance.

Eight months of rock-solid reliability since reprogramming. Lower fuel consumption with more power.

$25,000+ in uncovered repair bills and towing charges across four trucks, all DPF-related. Only ran right on the 40-mile drive back from the Cummins dealer. Ready to sell the fleet at a loss.

ECMs reprogrammed. All four trucks ran an entire winter on the road earning money instead of costing money.

Water truck used for dust control on excavation sites. Dealer told us to take it on the highway for two hours to complete regen — except the truck is jobsite equipment, not a highway tractor. Constant shutdowns.

ECM returned in 2-3 days. Truck now idles and sprays water all day without problems. Crew and truck stay on the job site producing revenue.

Certified pre-owned T800 in oilfield service with 24/7 idle and slow-speed operation. Almost immediate EGR valve failures and clogged DPF filter. Two dealer regens didn't hold. Another vendor on the job site referred ECM Performance.

Shipped ECM, back in three days. No more EGR or DPF issues. Idles all day and night without a problem.

DPF wouldn't clean, recurring stop-engine and check-engine lights, de-rates, limp modes, and shutdowns — at only 50,000 miles. Dealer mechanic referred us to ECM Performance.

Reprogrammed ECM installed three days after ordering. No more problems.

Auction-purchased bucket truck with reduced power in PTO mode from the start. Only 300 additional miles before the truck died completely.

Flew the ECM to Fort Lauderdale, programmed and returned same day. Truck started right up back in Panama City. Now at 8,000 miles with better than full power.

Previous-year 2011 F-750 export trucks had ongoing shutdowns, red stop-engine lights, and check-engine lights once in service overseas. Local service identified high-sulfur diesel fuel as incompatible with the DPF aftertreatment.

Transported the three 2012 trucks directly to ECM Performance before port shipment. Programmed same day. End user removed DPF and urea injection — happy with results. Sending three more ECMs from prior-year fleet for retrofit.

Brand-new 579 with MX-13 power for coast-to-coast South African long-haul. Ongoing derates, check-engine lights, and total shutdowns. Dealer and local service offered only temporary, expensive 'solutions' that didn't hold.

Shipped the ECM to Florida from South Africa. Programmed and returned within a week including both-way international shipping. 100,000 km of trouble-free operation since.

Brand-new mine service trucks wouldn't run on local Congolese diesel fuel. DPF aftertreatment incompatible with available fuel quality. DEF fluid not easy to source in the Congo. Removing the DPF without reprogramming wouldn't let the trucks start.

ECMs overnighted from Congo to Florida and back in a week. Mechanic reinstalled, removed DPF DOC and SCR internal elements. Trucks run with no problems and no engine codes; PTO mode runs great.

Two turbos replaced and the DPF filter cracked — truck no longer running. Manufacturer recommended international overnight shipment of the ECM to ECM Performance.

One week turnaround for international shipment. Pulled DPF, replaced with straight pipe, plugged in reprogrammed ECM. Truck fired right up. 6,000+ hours of smooth-idling, problem-free operation since. Sending four more ECMs.
