About Construction Calibrations
An Oklahoma diesel shop focused on one thing: getting heavy equipment ECMs programmed right.
Who we are
Construction Calibrations is based in Oklahoma. We have worked in diesel tuning since 2012 and have programmed thousands of machines, from construction and asphalt fleets to equipment from nearly every major construction, agricultural, forestry and mining brand.
Our owner grew up in agriculture and ranching and still runs a working farm. We know what downtime costs, and we build our process around getting your machine back to work.
Frequently asked questions
How do I know you can do my machine?
Search our capabilities list, then send us the ECM part number or label photo. We confirm the exact module before you ship anything.
How long does it take?
Programming itself is quick. Total time depends mostly on shipping. We give you a turnaround estimate with every quote.
Can you put it back to stock?
Yes. We save the original software before any change and can reload it at any time.
Do you remove emissions equipment?
No. Our calibrations work with the emissions hardware installed on the machine.
Do you ship outside the USA?
Yes. We regularly work with customers in Africa and other regions. See shipping details.
How do I pay?
We invoice after confirming your quote. Card, bank transfer and wire are accepted for international orders.
