Data Broadcasting format as implemented in the MS2/Extra and MS3 firmware. This format consists of

288 data channels and 74 enumerated status channels. This definition represents the entirety of the

channels that are possible but your specific ECU and firmware level will determine which of these

channels are actually present and transmitted.

CAN Bus Wiring on the CD-5 & CD-7

The AEM CD-5 & CD-7 each have 2 separate CAN ports. For 3

party devices, AEM recommends you

use AEM CAN BUS 2, whose connection can be found in the 2 pin Deutsch DTM connector with Grey

and Black wires.

CAN Bus Wiring – Termination Resistor

Consult your hardware specs to see if a CAN termination resistor is required at your device and how to

implement it. 2 terminating resistors are required, one at each end of the network.

The AEM CD-5 and CD-7 have a software selectable terminating resistor which is activated in the base

Megasquirt template so no further action regarding terminating resistors is required on the dash side. If

only 2 items are on the CAN bus then a terminating resistor is used at each device and one will be

required at the other end. If a 3

(or more) device is added then some of the devices will need to be

unterminated.

CAN Bus Wiring on the ECU

There are many different Megasquirt hardware versions available so a single hardware wiring diagram

is impossible to produce. Consult with your hardware technical reference to determine the location of

the CAN port connections on the ECU you wish to use.

MEGASQUIRT CAN HI  AEM CAN 2+ (pin 1, Silver wire)

MEGASQUIRT CAN LO  AEM CAN 2- (pin 2, Black wire)

ECU Software Setup for MS3 based ECUs

The settings are on the CAN-Bus/Testmodes menu of the TunerStudio MS Suite:

CAN-Bus/Testmodes  CAN Parameters

Set Master enable to "On"

CAN-Bus/Testmodes  CAN Realtime Data Broadcasting

Set “Enable realtime data broadcasting over CAN” to "On"

The Base message identifier needs to remain at the default of 1520

For each group of channels required, the broadcast frequency should be set to enable that group.

ECU Software Setup for MS2 based ECUs

The settings are on the CAN-Bus/Testmodes menu of the TunerStudio MS Suite:

CAN-Bus/Testmodes  CAN Parameters

Set Master enable to "On"

CAN-Bus/Testmodes  CAN Realtime Data Broadcasting

Set “Enable realtime data broadcasting over CAN” to "On"

The Base message identifier needs to remain at the default of 1520

Set the “Broadcasting Rate” to an appropriate value (20Hz is good)

For each group of channels required, set the group to “On” to enable that group for broadcast

AEM Setup in DashDesign

The fastest way to get something working is to use the AEM created setup for the Megasquirt Real-Time

Data format.

It is titled “Megasquirt_Realtime.aemcd7” and can be found in the same location as this document

was. This is a version of our default black layout that has the CAN inputs pre-configured and includes all

of the channels listed earlier. If you choose this method then simply load this configuration into the dash

and as long as the MS ECU is wired to the AEM CAN Port 2 then you are done.

STOP HERE!

You only need to continue if you choose to not use the AEM supplied layout and

wish to add Megasquirt Real-Time CAN support to custom or other existing

layouts.

Adding Megasquirt Real-Time CAN on different layouts

If you want to create something from scratch, you can either start with a new dash layout by selecting

“File” then “New” in DashDesign or you can select from a pre-designed layout that has screens already

designed and inserted but has the CAN inputs left blank. These are chosen by selecting “File” then

“Open” and selecting one of the setups titled xzyblank.aemcd7 with the xyz representing a description of

the layouts contained in the file.

To import the CAN configuration into your setup you select “Setup” then “Display” from the main

DashDesign menu. Once the dialog box opens you select the “CAN Receive” tab.

Make sure the port settings are as

follows:

Show: “Port 2”

Baudrate: 500 kbit/s

Termination Resistor: “ON”

Address Mask: “OFF”

M800 Support: “OFF”

Then click on “Import CAN” on the lower left and select the

MS Realtime CAN setup file:

“Megasquirt_Realtime_Rev0.aemcan”. This will present

you with a list of all 64 possible groups contained in the

configuration.

NOTE: All groups will be selected by default. Deselect all

the groups your ECU is not putting on the CAN Bus. This

is important since if you import all the channels then you

will be scrolling through literally hundreds of selections

every time you open a channel list box.

After you deselect the unused groups

and click on the import button, the

CAN listbox will be populated with the

remaining channels. They can now be

viewed on the display or logged. You

can rename, filter, or manipulate any

of these channels to make them more

useful.
