if I uncheck the “send EMU stream over can bus” in CAN, serial CAN setup box, will it still send a couple of user defined CAN messages to my transmission control unit ?
it is currently checked and mostly working but I have a problem where the VSS sometimes drops out and the TCU really doesn’t like that. i think that the TCU and the EMU Black are both sending something on the same address.
Please excuse my ignorance, i am learning (the hard way!)
If you have the “user defined stream” selected in the CAN dash drop down, then yes it will keep sending that CAN data regardless of if the “Send EMU stream..” checkbox is selected
Just so I understand fully; you’re concerned your TCU and the Black are sending data on the same x600 (up x610 I think) and the collisions are causing the TCU to miss receiving VSS info?
What trans controller?
You can change the address from x600 to something else if you can control the TCU’s receiving address (or whatever device you are having receive data from the Black like dash or PDM) and use the user defined stream for the TCU specific data.
Thank you, this has cured my issue. I have an Ofgear 722.6 TCU and Mercedes gearbox.
I dont recall enabling the EMU data, so was reluctant to turn it off. However, it was causing VSS to Ofgear data “dropouts” which in turn was messing with TCU operations. I have a couple of user defined things being sent which now work properly. I was worried it wouldnt send anything at all.
I will add some more user defined messages or change addresses in the future as i want to add a couple of ESP32 gauges, preferably on Canbus.
Thank you for taking the time to help me.
