About Us

Diesel ECM Exchange is the leading online supplier of rebuilt, high quality diesel engine control modules (ECMs). Family owned and operated, we pride ourselves on our excellent customer service and aim to get you and your vehicle back on the road as quickly as possible.

Our highly trained, certified technicians test, program and flash the latest OEM software and updates from the manufacturer on every computer we sell, and customize it with your car's exact mileage and VIN. That means that when you purchase an ECM from us for your diesel engine, you can rest assured that it is tailored exactly to your vehicle and programmed to help its engine run at optimum performance.

We carry ECMs for Dodge, Cummins, Caterpillar, Detroit Diesel, Ford, International, and Mack and all of our modules are plug and play. We do the programming heavy lifting and all you have to do is plug it in once we send it to you - no need to waste time and money at the dealer! Plus, we run every computer unit through a computer aided engine simulator to test for quality and back all of our ECMs with a lifetime warranty to put your mind at ease.

Please feel free to call or email us with any questions. We're here to help in any way we can!
