Komatsu dozers ECM tuning & reflashing
We program engine control modules for 12 Komatsu dozers applications, running control units such as the Cummins CM2350A, Cummins CM850, Cummins CM2250 and Cummins CM2850A.
What we do for Komatsu dozers
Performance calibration for more usable power and better fuel use, stock software reloads and updates, and recovery of Komatsu modules that failed during a flash. The original file is saved before any change and can be reloaded at any time, and engine protections stay active.
How to order
Send the model, serial number and a photo of the ECM label. We confirm the exact module against our list, quote it, and you ship the ECM to our Oklahoma shop from anywhere in the USA or overseas.
In diesel tuning since 2012, with thousands of machines programmed.
