Do you have an older AEM Series 1 or MoTeC M4-based programmable ECU that only outputs through a serial port connection? Then we have your racing digital dashboard solution! AEM's Plug & Play Serial-to-CAN bus Communication Harnesses convert the data stream from the serial data ports on AEM Series 1 and MoTeC M4/M48/M8/MLS/M2R programmable ECUs into AEMdata CAN bus for display and logging on CD Carbon Digital Dash Displays. These adapter cables provide a one-plug connection and are already configured in DashDesign 2.0 software to import, making them easy to set up and configure.
