EMU PRO 8: EGT channels 5-8 status "Unused (0)"

EMU PRO
1

Hello everyone,

I am having an issue with activating EGT channels 5 to 8 on my EMU PRO 8 on a V8 engine project. I am using an Ecumaster EGT-to-CAN module.

The setup:

  • ECU: Ecumaster EMU PRO 8
  • Engine: 8 Cylinder
  • EGT Module: EGT-to-CAN V2 (sending on custom IDs 0x610 and 0x611)

The problem:
Channels EGT 1 to 4 work perfectly, showing “OK (1)” and plausible temperatures. However, channels EGT 5 to 8 remain stuck on 0 °C with the status “Unused (0)”.

What I have verified so far:

  1. The CAN data arrives flawlessly at the ECU. In the Variables Inspector, my custom channels c_channel5 to c_channel8 show correct room temperature values (around 23–24 °C).
  2. If I map the CAN ID 0x611 (which holds EGT 5-8) to the software channels EGT 1-4, it works immediately. This proves that the CAN stream, the IDs, and the hardware are 100% fine.
  3. No matter what I try, the software keeps EGT 5-8 in the “Unused (0)” state. I looked for a global “Number of EGT sensors” or an “Enable” switch inside the EGT 5-8 parameters, but couldn’t find a way to force them to active.

Is this a known bug in the current firmware version, or is there a specific setting in the Engine / Bank / Cylinder configuration that I missed to unlock Bank 2 / EGT channels 5-8?

I have attached a screenshot of my client window and my current .emupromap file.

Thanks in advance for your help

Have you opened the EGT software and confirmed that you have temps being reported on 5-8? Have you confirmed the defalut id’s are 1552 and 1553? What about endianness? The default endianness should be Intel byte order and your using Motorola.

In EMUpro what does live capture show for 5-8? The image you attached shows unused due to no data and I assume a CAN timeout.

Thanks for checking bravo685!

Actually, if you look at the (screenshot) Variables Inspector in the top right corner, it seems the data is already arriving there quite nicely. The custom channels c_channel5 to c_channel8 are showing stable room temperatures around 23–24 °C.

Because of that, I think the CAN connection, the custom IDs (which are indeed 1552/1553 in decimal), and the Motorola endianness are probably set up correctly for this module, as the raw values look very plausible.

Also, when I test-map that same CAN ID 0x611 to the EGT 1–4 software channels, they instantly change status to OK and display the temps.

It really feels like the CAN side is happy, but the EMU PRO firmware is choosing to keep EGT 5–8 in the “Unused (0)” state for some reason. Could this be related to a specific cylinder/bank configuration or a software lock that I might have overlooked?
