What is ECM Tuning?

ECM Tuning is a process in which a technician edits your engine software to improve fuel economy and increase power.

Your engine is controlled by an electronic management system.

ECM Tuning is the process of fine-tuning that software in order to increase power, improve response and lower fuel consumption — all in one go. When done properly — which our certified technicians always do — ECM tuning has little to no negative effect on exhaust emissions. And perhaps the best part of all, ECM tuning increases the overall lifespan of an engine.

The rising price of fuel in North America has led to a vast increase of drivers opting for ECM tuning. It's an investment that usually pays off in fuel savings within the first 3-6 months. 3K Calibrations is the leader in ECM tuning for heavy trucks.
