Caterpillar skid steer loaders ECM tuning & reflashing
We program engine control modules for 18 Caterpillar skid steer loaders applications, running control units such as the Caterpillar A5M12, Denso 112500-1xxx, Denso 275700-1201/3410/3411/3412, Denso 275700-7122, Denso A6E11 and Denso A6E10.
What we do for Caterpillar skid steer loaders
Performance calibration for more usable power and better fuel use, stock software reloads and updates, and recovery of Caterpillar 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.
