AEM’s CD-7 OBDII CAN Plug & Play Adapter Harness makes the CD-7/CD-7L the perfect racing display for track day enthusiasts
who want to be able to see engine and vehicle data but are still running a factory ECU. This is especially true when
the CD-7 or CD-7L (logging) Digital Dash and OBDII CAN PNP Adapter Harness is combined with the Vehicle Dynamics
Module to add GPS, 3-axis accelerometer and 3-axis gyroscope for track mapping and lap times, and critical vehicle
dynamics data including G-loads, roll, pitch and yaw. And for CD-7 owners with CAN OBD-II who are already using the
dash and receiving channels from a data logger or other CAN-enabled device, you can now add additional channels through
the OBD connection with no additional wiring!
With the release of CD-7 software version 1.01.0X, all CD-7 Digital Dash Displays have the ability to read CAN bus data
from the OBDII port of 2008-up vehicles with a simple firmware update to DashDesign software version 1.01.04b. To
help with the installation, AEM has also made it easy to connect to the OBDII port by creating an optional CD-7 OBDII
CAN Sub Harness (PN 108-30-2217) that provides plug & play access between the CD-7 harness and the vehicles OBDII
connector. AEM’s CD-7 Plug & Play Power Cable is included with the OBDII Plug & Play Adapter Harness to make
an easy power and ground connection for powering the dash.
Once the CD-7 OBD-II CAN Sub Harness is connected, the dash polls the vehicle’s CAN bus to see what channels are available
and what speed they are being delivered. Users can then select the channels they want to add to the display, set
alarms for available channels and log them if using a CD-7L logging dash.
Although the CD-7 cannot control the data rate that available channels are transmitted (since this is determined by the
vehicle manufacturer), users can prioritize channels to optimize them for the best available transfer speed
