The CD-7/CD-7L color digital displays feature a super bright, high contrast, sunlight readable display and include an integrated glare diffuser and shade hood so that they are readable in even the brightest daylight conditions. They are designed to accept channels from CAN bus connections and do not include analog inputs.
Two CAN bus channels are included so that it can receive and collect data from AEMnet enabled devices such as the Infinity ECU, Series 2 EMS or EMS-4, and 3rd Party Devices, including PDM’s, CAN sensor modules and programmable engine management systems. The CD-7 is ECU CAN ready and does not require external modules for CAN to CAN communication, just load your configuration and go! Third-party systems will require download of 3rd party DBC CAN bus protocol files for proper operation if they are not
included in our setup software. We currently have over 150 validated 3rd party applications, and offer a CD-7 Power Cable to simplify the
installation of 3rd party devices. We have also developed 3rd Party Plug & Play Adapter Cables for certain applications.
Seven ultra-bright LEDs span the top of the display housing for RPM and shift light indication. Users can program them to
ascend in specific increments based on RPM range, and flash when it is time to shift. Brightness is user programmable
on the fixed color LEDs. Two large buttons are included on the face of the display, allowing easy page changing and memory
resetting even with driving gloves on. These button functions are also duplicated on the rear connector allowing the
user to mount remote buttons on the steering wheel if desired. Two additional programmable LEDs are located above the
toggle buttons on the sides of the housing.
Four packages are available:
AEM’s CD-7 Power Cable (PN 108-30-2218) simplifies power and ground connections for the CD-7 Digital Dash Display for non-AEMnet
equipped, 3rd Party device harnesses (the CD-7 is powered through an AEMnet connection on equipped devices,
and does not require a Power Cable). The CD-7 Power Cable connects to the AEMnet connector on the CD-7 wiring harness
and includes a pigtail connection with power and ground leads, allowing for CAN connection to 3rd Party
devices through the CAN 2 connector on the CD-7 main harness.
The CD-7 Power Cable is designed for 3rd party, CAN-based ECUs, data loggers and devices, and AEMnet devices
that do not have an AEMnet connection built into the wiring harness. Most Infinity Plug & Play Adapter harnesses
and the EMS-4 Universal Flying Lead Wiring Harness include an AEMnet connection. Users of Series 2 EMS systems may
elect to use the CD-7 Power Cable, or purchase an AEMnet Series 2 Adapter Cable for their application to connect the CD-7. For all other 3rd party devices, this harness will make it
easy to power the dash.
AEM’s Plug & Play CAN bus Communication Harness (PN 108-30-2214) eliminates the need to manually wire a CD-7 Digital
Dash Display to a Holley EFI system! This harness is fully terminated and connects the CAN2 input on the CD-7 main
harness to the CAN output on a Holley EFI harness.
Because the Holley EFI system does not provide power from the CAN output, AEM recommends using its CD-7 Power Cable (PN
108-30-2218) to simplify power and ground connections. The CD-7 Power Cable connects to the AEMnet connector on the CD-7
wiring harness and includes a pigtail connection with power and ground leads that make it easy to wire the dash for
power when used with non-AEMnet equipped devices.
AEM’s Plug & Play CAN bus Communication Harness (PN 108-30-2213) eliminates the need to manually wire a CD-7 Digital Dash Display to the MSD Atomic TBI Fuel Injection! This harness is fully terminated and connects the CAN2 input on the CD-7 main harness to the CAN output on the MSD Atomic TBI harness. Additional power cables are not necessary as the CAN connection from the MSD Atomic TBI will power the CD-7 Digital Dash Display via a “Y” connection to the AEMnet port for Power and Ground.
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
