Performance calibration
More usable power and better fuel use from the engine you already own. Tuned for the job the machine actually does, whether that is hauling in a pit or pulling a disc.
ECM reflashing for the machines that move dirt, crops and ore.
We program engine control modules for construction, mining, agricultural and forestry equipment. Ship us the ECM from anywhere in the world, or bring the machine to our Oklahoma shop.
In diesel tuning since 2012 — thousands of machines programmed.

Services
ECM reflash and updates
Stock software reloads, calibration updates and corrected flash files for modules that have been mis-programmed or need to match a replacement engine.
ECM recovery
Modules that failed during a flash, lost their software or will not communicate. We read them on the bench and bring them back where the hardware allows.
