Marine Mods GMLAN - N2k Gateway covers all High Speed GM CANbus protocols used on model years 2004 to 2019. Allowing OEM hardware builders the option to run NMEA2000 based MFD's or gauge sets, with just two wires on stand alone engine applications.

Rather than using a traditional OBD2 "request and reply" PID structure to gather gauge data, our code reads raw steaming data from the OEM ECM and TCM just like other GM CANbus hardware. For certain gauge parameters not inherit to a factory dash like IAT or Boost, we use Dynamic PID's to instruct the ECM to include this extra data inside the normal broadcast stream. This equals a much cleaner approach, with no delay or lag on the gauges displayed.

HS GMLAN or GM GLOBAL-A Protocol is fairly common across all GM models. However there are some slight differences in gauge related data packets between ECM hardware and OS versions. For this reason we have tried to split up the firmware configuration options based on ECM models. Please Contact Us with any compatibility questions.
