What Is Truck ECM Tuning?

ECM tuning recalibrates the software that manages the engine’s fuel system. The process does not require the replacement of engine parts. It may improve power, acceleration and fuel economy. A suitable calibration may also support more efficient combustion. This can help reduce certain maintenance costs.
