Perkins T402850R Engine Control Module

The Perkins T402850R is an Engine Control Module (ECM) designed for Perkins 2506 and 2806 series diesel engines, also applied to Caterpillar C15 and C18 engine platforms. This electronic control unit manages fuel injection timing, air-fuel ratio, and emissions control through real-time sensor monitoring. The module arrives unprogrammed and requires full calibration with engine-specific software before installation. It serves as a direct replacement for Caterpillar part number 478-7932 and FG Wilson 10000-90624, used in construction machinery loader grader applications and power generation generator sets. The unit operates on 24V electrical systems typical of heavy-duty diesel platforms.
