The MyChron 2 Port Data Hub with External Power can expand the capabilities of your AIM MyChron 4 Gauge.
The Data Hub allows connections of up to 2 CAN peripherals: GPS Module, E-Box, Data Key, LCU Lamba Controller, etc.
You can of course use more Data Hubs
in series to have all connections you want. Data Hub
takes all the information you need to your logger with only one cable, minimizing wires overall.
