The Caterpillar 785 dump truck is power by a Cat 3512C HD-EUI diesel engine produces 1348 HP from its 58.5 liters of displacement. The ECU controlling the engine functions is a Caterpillar ADEM4.

We at Alt Tune have the ability to reprogram the factory ECU and re calibrate the operating functions of the ECU.

Goals for 785 dump truck tuning.

The main goal for tuning a 785 dump truck is fuel savings and an increase in productivity, we can achieve both these goals via modifying the injection parameters and modifying specific limiters in the factory program. As a result of increasing the power and torque output via our ECU tune, the trucks will hold higher speeds in high load situations, such as when they are fully loaded and driving up a hill.
