RaceGrade RG EGT-8 Interface to CD Dash
Supported Devices
RaceGrade RG EGT-8
CAN Bus Wiring
AEM CD has 2 separate CAN ports. For 3rd party devices, AEM recommends you use AEM CAN Bus 2, whose
connections are contained in a 2 pin Deutsch DTM connector. On older harnesses it may be in an unterminated,
twisted/shielded flying lead in the dash harness.
RaceGrade RG-TC8 (CAN HIGH) AEM CD Dash "CAN 2" Pin 1 (CAN 2+), Gray wire in twisted/shielded pair
RaceGrade RG-TC8 (CAN LOW) AEM CD Dash "CAN 2" Pin 2 (CAN 2-), Black wire in twisted/shielded pair
The AEM CD Dash has a software selectable CAN termination resistor. Each CAN network needs 2 terminating
resistors, one at each end. The RaceGrade RG-TC8 does not have an internal terminating resistor and relies on
external terminating plugs. If your CD Dash is located at one end of your CAN network simply activate the CD
Dash’s internal resistor in the AEM DashDesign software. If the CD Dash is not located at one end of the CAN
network use external terminating resistors with one placed at either end of the CAN network.
RaceGrade RG-TC8 Software Setup
The RaceGrade Manager Suite software is not required if using a single RaceGrade RG-TC8 unit in its default
configuration. The DBC file provided for the RG-TC8 by AEM matches this default configuration.

Setup in AEM DashDesign
AEM has provided some pre-configured layouts that can be easily adapted to accept, display, and log (if using CD
Dash that supports logging) the CANbus channel data from the RaceGrade RG-TC8. The following steps will show
you how to quickly setup your TC8 to work with an existing AEM DashDesign Layout.
1. Visit www.aemelectronics.com/forum and scroll down to the CD Dash forum. This is a great place to find
answers to all AEM Dash related questions you may have.
2. Open your layout in AEM dashdesignDashDesign.

your device. You may can choose to import all of the channels available or you may select only the channels
you wish to display. For this example, I will include all available channels are selected. Unused channels can

8. In the “Setup Editor” under the “Outputs” tab, check to make sure the channels you selected to import are
present. If they are not, go back to step 4 and try again.
9. Find the output “TC1” and check that the Primary Input is “TC1_raw”. If it is not, change it now. If setting up
“TC2” the input should be “TC2_raw” and so on.
10.The correct scalar should be automatically set when you imported the .aemcan file. If you want to use the
default scalar and not create a custom one, skip ahead to step 11. The software automatically creates one
scalar for each of the TC8’s channels when the .aemcan file is imported. If the selected scalars are not correct
for your application you may change the scalar to a custom one. To create a custom scalar, go to the
“Scalars” tab in the “Setup Editor” window. Select “Insert” and create a name for your new scalar. Once
named, enter the correct scalar value and offset.

“Operation” column for your channel, select the new scalar. You do not need to make a different scalar for
each channel. . Simply Sselect the scalar for each output you wish to apply it to.

associated with the data from the TC8. This will open the “Value Editor”, “Dynamic Needle Gauge Editor”
or “Bar Editor” window depending on how you wish to display the data. Click on the “Input” drop down and
select the channel “TC1” or the channel you created. Click “OK”.
