Instructions for using AEM widebands with MSLabs CAN Wideband Module

1. Install your CAN Wideband Module according to the instructions from our website. Complete steps 1 through 4, then stop and complete these instructions.
2. Download the CAN Wideband Module INI file from our website: http://www.trackspeedengineering.com...nd-Module.html
3. Open your TunerStudio project. Click File>Project>Project Properties. Click the "CAN Devices" tab.
4. Next to CAN Devices, click the plus sign to add a device. Next to "Device Configuration File", click the "..." button. Navigate to the CAN Wideband Module INI file, click "open", then click "OK."
5. Your project will close and re-open automatically. In the upper left-hand corner, you will see a new Device drop- down menu. Select "CAN1" (or the custom name you used for your CAN module), then click "CAN Wideband Module Setup" at the top of the screen. Click "CAN Wideband Settings" from the dropdown menu.
6. Next to "Wideband Model" select "AEM" , then click "Burn", then "Close".
7. Click Tools>Calibrate AFR Table. Next to "EGO Sensor", select "Innovate LC-1/LC-2 Default" (not a typo - you must select Innovate even when using an AEM wideband). Click "Write to Controller", then "Close".
8. Complete steps 5 through 18 of the normal instructions.


Did you follow the instructions in step 7?

I use the AEM X UEGO and I want to connect it to the ms3pro via can as in the attached photo, I have the same WB.
I connect it directly to the CAN of the MS3PRO but in the software configuration it seems that something is wrong.
Question, is it very necessary to use the "MSLabs CAN Wideband Module"?
or the AEM X UEGO can't be connected directly?

No, if you do some searching you can find some posts on how to set up your MS CAN to work on AEM Net but you will loose the ability to connect any other CAN devices to your network.

So its confirmed I cant run AEM X With Canbus and Canchecked guage at the same time? Weird.. so AEM isnt real CAN?

So then its back to Analog Brown-Ground White-0-5v?


EDIT- saw this post... https://www.miataturbo.net/megasquir...an-bus-108238/

Anyone know if the canchecked gauge is ID-3?


And another clarification from https://www.miataturbo.net/general-m...series-108216/
To clarify here, AEM does speak normal CAN. AEMnet did not reinvent CAN. AEMnet is not some special CAN protocol, it is just a specific mapping of CAN message ID's to certain values, it is a unique CAN 2.0 data scheme. If you really want to see the details, you can scrounge for the datasheet for the protocol online, it used to be available straight from AEM but they may have taken it down. You can see some of the specific messages in the Infinity instructions as well:

Megasquirt 29-bit CAN is what does not speak normal CAN, that is it's own special protocol that is enabled by the "29bit Megasquirt CAN Enable" option. This is truly reinventing CAN. It is this protocol that is incompatible with AEMnet and, more generally, all other 29-bit CAN messaging schemes.

So, in theory, MS3 should be perfectly happy broadcasting 11-bit realtime CAN data for the CANchecked gauge while receiving EGO data via 29-bit CAN from the AEM X-Series wideband. That's not to say that the firmware is wonky and for some reason does not support this, but as long as "29bit Megasquirt CAN Enable" is off, it should work just fine.

If you don't have a need for the 29-bit Megasquirt CAN then you can disable it. Then you will be able to to configure the the MS3 to receive 29-bit AMEnet message (firmware dependent). The MS3 can be configured to rebroadcast the AFRs using the a 11-bit CAN message that the Canchecked gauge can read. I have both AEMnet (30-0310) and Canchecked co-existing on the same CAN bus.
