Veteran Discount: 10% Off Diesel ECM Repair, Programming & Tuning

To everyone who has served in the United States Armed Forces: thank you.

We built this program because a large share of the modules that arrive at our bench come from veterans, and the vehicles they care about are the ones they use on their own time. A Ford Super Duty that has to pull a boat 300 miles without dropping into limp mode. A diesel motorhome that has to climb a mountain pass with the whole family inside. An outboard that has to start on the first turn of the key, twelve miles offshore.

When the engine control module on any of those fails, the trip stops. So does the work. Our job is to get that module diagnosed, repaired, and back in your hands — and for veterans, to do it for 10% less.

Who Qualifies for the Veteran Discount

The discount is tied to your service, not to your vehicle. If you qualify, it applies to any module we service.

• Veterans of the Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard, with an honorable or general discharge
• Military retirees
• National Guard and Reserve members who have completed their service obligation

Any one of the following works as proof of status:

• DD Form 214 or NGB Form 22
• VA Health Identification Card or a VA benefits letter
• Veteran ID Card (VIC)
• A state driver's license or ID with a veteran designation
• ID.me, GovX, or Veterans Advantage verification

You do not need to mail us the document. A photo or screenshot sent with your service request is enough, and we do not retain it after the order is verified.

Why ECM Reliability Matters on a Truck, a Boat, or an RV

The engine control module is the computer that decides how your engine behaves. It reads the sensors, controls fuel delivery and injector timing, manages boost, communicates with the transmission, and decides whether the engine makes power or derates to protect itself.

When that module starts to fail, it rarely looks like an electronics problem at first:

• Power loss or a hard torque limit that only shows up under load
• Rough or erratic shifting, or a transmission that hunts between gears
• Hard starting, extended cranking, or intermittent no-start conditions
• Diagnostic trouble codes that return after the mechanical repair is finished
• Stalling that nobody can reproduce in the shop
• Communication faults — a scan tool that cannot see the module at all

Those same symptoms are what lead to injectors, sensors, and wiring harnesses being replaced when they were never bad. On high-mileage diesel trucks and on older marine and RV platforms, the module itself is often the real fault: cracked solder joints from years of vibration, failed driver circuits, moisture and salt corrosion, or a degraded internal power supply.

Two things follow from that. First, a proper diagnosis of the module can save you the cost of replacing good parts. Second, repairing the original unit is usually faster and less expensive than buying new from a dealer, and it preserves your existing VIN and calibration data — which avoids a second round of dealer appointments just to make the vehicle run. You can see exactly how we handle each unit on our ECM repair process page, and if you need to identify a connector before you pull the module, our ECM pinout library is free to use.

Veteran Discount Truck Repair: ECM Service for Diesel Pickups and Heavy-Duty Trucks

Diesel trucks are the largest part of our work. Whether you are towing a bass boat, a fifth-wheel, a car trailer, or running the truck for a living, the module has to hold up under sustained high load — and that is exactly the condition that exposes a marginal ECM.

Our heavy duty truck ECM repair service covers diagnosis, component-level repair, reprogramming, cloning, and full bench testing before the unit ships back to you.

Ford Super Duty ECM Repair & Programming

We service the full Super Duty and medium-duty line — F-250, F-350, F-450, F-550, F-650, and F-750 — including 6.0L, 6.4L, and 6.7L Power Stroke engines and Cummins-powered medium-duty chassis.

What we see most often on these trucks:

• Power loss under load — the truck pulls fine empty and falls flat with a trailer behind it
• Injector driver failures inside the module, frequently misdiagnosed as bad injectors
• FICM faults on 6.0L platforms
• Transmission complaints — late or harsh shifts, or torque management that cuts power on grades
• Persistent DTCs that come back after the mechanical work is done
• No communication with the module on a scan tool

Our Ford F250 F350 ECM programming service includes flash programming, software updates, VIN programming, calibration file installation, and complete module setup, so the unit arrives configured for your specific truck instead of needing a dealer visit to finish the job.

Browse the exact service you need: Ford ECM repair, Ford TCM repair, or a remanufactured Ford module. Pickup applications fall under light duty ECM repair; F-650 and F-750 chassis fall under heavy duty ECM repair.

Chevrolet & GMC Heavy-Duty Trucks

We repair and program modules for the Silverado 2500HD, Silverado 3500HD, GMC Sierra 2500HD, and Sierra 3500HD, covering LB7, LLY, LBZ, LMM, LML, and L5P Duramax applications.

Typical faults include CAN communication dropouts, glow plug and injector control circuit failures, water intrusion on modules mounted in exposed locations, and corrupted calibrations that leave the truck stuck in a reduced-power state.

See our Chevrolet Duramax ECM repair services, Duramax replacement modules, and GMC FICM units.

RAM Heavy-Duty Trucks

For RAM 2500 and RAM 3500 trucks with the 5.9L and 6.7L Cummins, we handle ECM and TIPM repair, PCM and TCM programming, and cloning when a module has to be replaced but the original data needs to be preserved.

Common complaints are intermittent no-start conditions, fuel control circuit faults inside the module, and torque limiting that only appears when the truck is loaded. Start with our Dodge RAM repair and replacement page or browse RAM Cummins modules.

A Note on Performance Tuning

We offer emissions-compliant calibration work aimed at towing drivability: smoother torque delivery, better throttle response under load, and improved fuel economy at highway cruise. We do not build or install calibrations that remove, disable, or defeat factory emissions equipment.

Our calibration services are organized by application: truck tuning, Cummins truck tuning, and cloning and programming. There is an overview on our diesel tuning, cloning & programming page.

Marine ECM Repair Service

Marine electronics live in the worst environment we work with: salt air, standing humidity, wide temperature swings, constant vibration, and — on a lot of boats — a module mounted somewhere that will eventually see water.

Our marine ECM repair service addresses the failures that come with that:

• Corrosion on the circuit board and connector pins, often visible before any code sets
• Moisture intrusion through failed gaskets and degraded potting compound
• Intermittent misfires and stalling that show up on the water and disappear at the dock
• Sudden power loss or a jump into protection mode mid-run
• Trace and solder joint degradation from years of salt exposure

We work on both outboard and inboard applications. Go straight to your platform: Mercury & MerCruiser, Mercury outboard ECU repair, Volvo Penta, Cummins Marine, or Caterpillar Marine. The complete list is on our marine ECM repair page, and calibration work is under marine tuning.

Every marine module we rebuild is resealed to marine-grade standards and bench-tested under load before it ships. On a truck, an intermittent electronics fault is an inconvenience. Twelve miles offshore, it is a safety problem — so marine units get the most conservative rebuild standard we apply.

RV ECM Repair and Tuning

A diesel motorhome is a house that has to climb grades at 20,000 pounds and up. When the ECM in a diesel pusher fails, the trip is over and so is everyone's vacation.

Our RV ECM repair and tuning service covers Class A and Class C diesel motorhomes and diesel pushers running Cummins ISB, ISC, and ISL, Caterpillar C7 and C9, and Detroit Diesel engines.

What we see most often:

• Low power on long grades — the coach derates halfway up a pass
• Derate and limp mode events caused by failed internal sensing circuits
• Aftertreatment faults traced to module-side control failures rather than the exhaust hardware
• Electrical gremlins on coaches that sit for months between trips
• Fuel economy loss from a corrupted or drifted calibration

Because most RVs are stored between uses, these faults tend to surface on day one of a trip, hundreds of miles from anyone who can help. Having the module checked before the season starts costs a great deal less than a tow.

Coach engines are handled by engine family: Cummins, Caterpillar, and Detroit Diesel.
