Marine Diesel ECM Tuning

Marine diesel ECM engine tuning for fuel efficiency

Improve Performance and Reduce Fuel Consumption

ECM tuning your marine diesel engine will safely increase horsepower and torque resulting in improved responsiveness and reduced fuel consumption.

Updated ECMs typically return 5% to 20% in fuel efficiency and both horsepower and torque gains up to 20%. Our engineers tune your ECM (also called remapping or chipping) by connecting to your engine remotely or through the diagnostic port with special software to read your factory settings then modify the mapping tables to deliver the performance needed to suit your vessel and application.

The completed tune is then reloaded onto your ECM where a number of validation tests are performed. A copy of your original configuration is safely stored and can be reloaded if you need to go back to original equipment specifications.


Improve horsepower and torque and reduce fuel consumption with a custom fuel efficiency tune or Plug-In Power module. Diagnose and fix problems with our Laptop and Diagnostic Software package.
