Kustom Truck Data Management Processor (GPLM-04) – Patented J1587/J1939 Translator
This patented device acts as a bidirectional translator between older J1587 (analog) engine electronics and modern J1939 (digital multiplex) chassis systems. It enables full dash functionality — including gauges, switches, engine brake, cruise control, and more — when installing J1587-based engines into trucks with J1939 chassis electronics.
