Inside the engine's computer
ECM, Gains And Process.
A diesel with its engine control module and a laptop on the line: what the ECM controls, what tuning changes, and how the software gets reprogrammed.
What The ECM Controls
The engine control module controls various functions of the engine, including fuel injection, timing and more. Its software settings decide how the engine runs, and that software is what performance tuning optimizes.
What Tuning Can Do
By optimizing the ECM's software settings, performance tuning can increase horsepower and torque, improve fuel efficiency and even reduce emissions: a significant increase in overall performance and efficiency for a heavy-duty diesel.
How ECM Tuning Is Done
Tuning isn't suitable for every heavy-duty diesel, since some have specific restrictions or requirements, so the truck and its software get assessed first. Then the team connects to the truck's computer and reprograms the software in-house, with state-of-the-art equipment and the latest software.

What drivers notice first
Signs A Truck Could Use Tuning.
Where each one usually leads. Tuning comes after the truck checks out, so a fault gets fixed first, not tuned over.
Fuel Costs Running High
Fuel is one of the biggest costs a truck has. Tuning can improve fuel efficiency, which adds up across a fleet over time.
