ECU software for John Deere, Caterpillar and heavy-duty trucks

ECULogicX is an independent provider of ECU software solutions for agricultural machinery, construction equipment and heavy-duty trucks. We supply calibration files, diagnostics support, DTC solutions and performance software for the most common engine control units in the field — from Bosch EDC17 and MD1 in John Deere and Claas tractors, to Caterpillar ADEM and C-Series ECMs, to Scania EMS S6/S8, MAN, DAF and Volvo truck controllers.

Every solution is engineered on your original read-out and delivered with a written change log. Dealers, workshops and fleet operators in the United States, Australia and Europe use the three portals to find the right software by manufacturer, machine and ECU. TheGreen covers John Deere, TheYellow covers Caterpillar, and Truck covers on-highway heavy-duty brands.

Frequently asked questions

Which portal do I need?

John Deere machines go to TheGreen, Caterpillar machines to TheYellow, on-highway trucks (Scania, MAN, DAF, Volvo, Mercedes-Benz, Iveco) to Truck. Other brands: use the "Ask the engineer" box above or search by ECU type.

What do I need to order a solution?

The original file read from the ECU, the machine or engine model, and what you want solved. Upload it in the portal, we quote scope, price and delivery time.

How fast is delivery?

Most standard files are returned within the hour during support windows in the US, Australia and Europe. Complex diagnostics jobs are quoted individually.

Are you an official John Deere or Caterpillar site?

No. ECULogicX is independent and not affiliated with any manufacturer. Brand names are used only to identify the machines and ECUs our software supports.

Is every solution legal in my country?

Availability and admissibility differ by region, machine class and intended use. Each product page states where and for which applications it is offered.

I'm a workshop or reseller. Do you offer dealer pricing?

Yes — volume pricing, a priority file queue and a named engineer contact. Apply for dealer access.
