Cummins

19 cases

The largest single engine population in our case library. Cummins B6.7, ISB, ISC, ISL, ISM, ISX, and X15 platforms across vocational, agricultural, refuse, snow plow, fire/EMS, and long-haul applications.

2011 Kenworth T370, 2011 Ford F-750, 2012 Freightliner M2 — bucket / utility fleet
Cummins ISC / ISL

Three weeks of zero limp mode, PTO, or shutdown issues. We made a huge difference in the storm relief — and earned a huge payday.

The Problem

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.

Outcome

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.

Cummins 8.3 ISC / Paccar PX-8

After dealer-replacing turbos, EGRs, DPF filters and DOCs without fixing the problem, ECM Performance gave us a real solution. Wish I'd known about them four years earlier.

The Problem

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.

Outcome

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.

Freightliner M2 fleet
Cummins ISB / ISC

Freightliner and Cummins couldn't fix our cold-weather DPF problem. ECM Performance did.

The Problem

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.

Outcome

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

Steve R.
Emergency service and plowing — local municipalities
2008 Freightliner M2
Cummins ISC 8.3

No engine lights, no regen, no foul smoke. No problems anymore.

The Problem

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.

Outcome

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

2007 Peterbilt 335 feed truck
Cummins ISB 6.7L / Paccar PX-6

My advice to anyone reading this: the sooner you do this, the better off you'll be.

The Problem

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.

Outcome

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

Ted
Cattle farmer
2010 Kenworth T370 service truck
Cummins ISC

Like magic. No more codes or problems. Wish we knew about this a year ago.

The Problem

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.

Outcome

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

Harold J.
Field equipment service — logging industry
2009 Kenworth T370 dump truck
Cummins ISC 8.3L 330HP

Highly recommend ECM Performance to anyone experiencing DPF-related issues.

The Problem

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.

Outcome

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

2009 Allianz Johnston 4000 sweeper, 2008 Freightliner refuse truck
Cummins ISC / ISB

Best money we ever invested in a vehicle repair. My boss thinks I'm a hero for solving this.

The Problem

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.

Outcome

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

Kenworth T-300 farm truck — 500,000 km
Cummins ISC

I'm telling everyone about you guys.

The Problem

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.

Outcome

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

Mike K.
Farmer
Ford F-650 flatbed
Cummins ISB 6.7

Truck now gets 14 MPG. It used to get 8-9 mpg. The reprogramming pays for itself in fuel savings.

The Problem

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.

Outcome

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.

Rudy E.
Farmer
2008 Ford F-650 dump truck
Cummins ISB 6.7

Very happy with the programming, turnaround time, and support. Would definitely recommend.

The Problem

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.

Outcome

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.

2008 Sterling Acterra — 36,000 miles
Mercedes-Benz MBE 900 / Cummins ISC

With no DPF, this truck runs better than ever. We feel confident to send it anywhere, anytime.

The Problem

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.

Outcome

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

Barry K.
Septic service
New 2011 Ford F-650 — 10,000 miles
Cummins ISB 6.7

Truck now runs without any code or limp mode for the first time since we bought it.

The Problem

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.

Outcome

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

Bill E.
Municipal vehicle recovery contract
2008 Peterbilt 335 roll-off — 140,000 miles
Cummins ISC 8.3

Better than a brand new truck. After dozens of dealer visits over 140,000 miles, ECM Performance solved it in three days.

The Problem

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.

Outcome

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

2008 Kenworth T300 service truck — 84,000 miles
Cummins ISC

Eight months with no problems. Rock solid reliable. Fuel consumption is down with more power.

The Problem

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.

Outcome

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

2009 Kenworth T300 water tank truck — 120,000 miles
Cummins ISC

Idles and sprays water all day with no problems. Now we stay on the job site making money instead of costing money.

The Problem

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.

Outcome

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.

2008 Sterling bucket truck — 900 miles, 540 service hours
Cummins ISC

Flew in with the ECM, had it back the same day. Best money we ever spent.

The Problem

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

Outcome

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.

Three new 2012 Ford F-750s
Cummins ISB 6.7

End user removed the DPF and is now very happy with these latest trucks. Sending three more ECMs from last year's delivery your way.

The Problem

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.

Outcome

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.

Carlos V.
Import / Export — trucks destined for South America
2008 Ford F-650 fire truck — 1,000+ service hours
Cummins ISB 6.7

6,000+ hours of smooth idling and no problems. God bless you guys.

The Problem

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

Outcome

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.

Paccar

8 cases

Paccar PX-6, PX-7, PX-8, PX-9 medium-duty platforms in vocational and fleet service; MX-11 and MX-13 heavy-duty platforms in long-haul including international export cases.

2014 Peterbilt 579
Paccar MX-13

Got the ECM back in a week — including shipping from South Africa to the US and back. 100,000 km later, still running strong.

The Problem

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.

Outcome

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.

Pete Z.
Long-haul trucker — South Africa
Nine Peterbilt 340s
Paccar PX-8

Six weeks, no more problems on the reprogrammed trucks. Sending the rest of the ECMs in one at a time.

The Problem

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.

Outcome

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

Earl O.
Ready-mix concrete delivery — nine-truck fleet
Kenworth T300 dump truck fleet
Paccar PX-8

Both trucks working great. Thanks for the fast service.

The Problem

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

Outcome

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

Charlie G.
Excavation / mining company
Peterbilt 340 dump truck
Paccar PX-8

Customer service, turnaround, and results — all great. Tell your customers not to be afraid of ECM programming.

The Problem

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.

Outcome

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

Mark T.
Gravel company — Minnesota
Peterbilt 330 — 120K miles
Cummins ISC / Paccar PX-8

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

The Problem

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.

Outcome

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

Jose M.
Waste removal
Peterbilt 335 box truck — 80,000 miles
Paccar PX-8

You can't remove the DPF without reprogramming the truck's ECM. Big thanks to Jim and the fellas at ECM Performance.

The Problem

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.

Outcome

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

Four 2009 Peterbilt 335 propane tank trucks
Paccar PX-8

Four trucks on the road all winter long earning money instead of costing us hard dollars out of pocket.

The Problem

$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.

Outcome

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

Scott P.
Propane delivery
Three Peterbilt 337 mine service trucks — under 100 service hours each
Paccar PX-8

Trucks run with no problem, no engine codes, and the PTO mode runs great. Professional and quick service.

The Problem

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.

Outcome

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.

Caterpillar

2 cases

Cat C13 and C15 ACERT platforms — particularly oilfield service trucks running 24/7 idle and slow-speed duty that fights the ACERT calibration assumptions.

2009 Peterbilt 386 — 50,000 miles
Caterpillar C15

I wish we'd known about you guys a year ago. I would have saved a lot of money and had a running truck.

The 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.

Outcome

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

Hector P.
Agriculture / Farming — Mexico City, Mexico
2011 Kenworth T800
Caterpillar C13 ACERT

Idles all day and night without a problem. No more EGR or DPF problems.

The Problem

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.

Outcome

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