  • Due to backwards compatibility issues with the latest Cummins Insite program and Inline adapters, all calibrations and changes to parameters should be done by DSO Industrial. Damage done to ECMs by Cummins hardware/software is not covered under warranty. Read more here.


Send us your ECM, and we will test it for FREE. We may be able to pull the calibration specs off of it and avoid the core deposit!

Fuel Solenoid Relay Mod:

A leading cause of ECM burns (permanent, non-repairable damage) is from fuel solenoid shorts. When the fuel solenoid shorts out, it causes an amp draw greater than the ECM can supply. There is no hardware based protection in the ECM for this fault. Installing a relay between the ECM and the fuel solenoid isolates the ECM from this common failure. Please click here for instructions on installing this relay. Its cheap insurance!

DSO Industrial specializes in Cummins Celect and Celect Plus ECM s. If you need a new ECM after getting an unfixable trouble code, we have several options available.
Before you decide you need a new ECM device, go through the troubleshooting steps and find out if it is possible to repair your truck, rather than replace the ECM. Our technicians can help you out when you need advice during this process. We also offer free ECM testing if you need help diagnosing a problem. Our policy helps you get the right solution the first time rather than purchasing a Cummins ECM when your truck is what needed repairs.
Our remanufactured Celect and Celect Plus ECM s are produced with the highest standard of excellence in the industry. When you buy rebuilt parts from other companies, you will not get the same level of craftsmanship. We offer warranties on these products and we might be able to give you a credit when you send us a rebuildable core for your ECM. All Cummins Celect ECM s are tested on live trucks in our shop and are guaranteed to work. They are not just repaired; they are rebuilt like new, free of the defects and quality checked on our test trucks.
You can order an ECM from DSO Industrial and expect same-day shipping when placing an order before 2 PM CST. Our products are stocked and ready for shipping when you log your order. We understand that you are operating on a tight schedule and keep our shipping and delivery schedules tight. Our commitment to our customers is unparalleled in the industry. Ask about our free calibration for your CPL when you order a Cummins Celect or Celect Plus ECM. We also sell security kits for these models at very low prices.
Our used Cummins Celect and Celect Plus ECM s are sold at a great value to our customers. While they do not come remanufactured by DSO Industrial specialists, each used model is tested to be sure it is in working condition. We occasionally receive serviceable parts from truck dismantlers and are happy to pass them on to customers on a tight budget when in stock. They will not come with the warranty we offer for remanufactured units. If a device arrives DOA, we will replace it or refund your money. Please notify us within 24 hours if there is a problem with a used part.
Other options include non-rebuildable Celect ECM cores. These non-rebuildable items will range greatly in condition and type of fault. Unfortunately, we cannot provide information on the types of faults existing in each part. All non-rebuildable cores are sold AS IS and may be acceptable to Cummins as cores. Water damage might be present, as well as extensive circuit board damage. Cases may be damaged. Circuit boards are secured to the case. Each core will have a defect that is unspecified, as these items are sold for as non-fixable cores.
Our Cummins Celect remanufactured products represent top-quality craftsmanship and are highly recommended to replace your faulty ECM. Take advantage of our fast shipping and no-risk purchase process today.

ECM to Cooling Plate stainless steel replacement bolts!

  • Stainless Steel anti-theft ECM Bolts. 6 bolts and  bit driver for $30
  • A2 Stainless Steel standard (non security) bolts. 6 bolts for $10

Don't re-install those old corroded bolts to hold your ECM on. Using mild steel bolts into the aluminum fuel cooling plate is asking for issues, as we all know. 
We have sourced STAINLESS STEEL replacement bolts that use an un-common high torque button head pattern that not only provides a better stainless steel fastener, but greatly increases your ECM security, and helps avoid ECM theft at the same time (anti-theft kit bolts only). If you are not needing the anti-theft bolts, we also have A2 stainless steel standard bolts.
