Holley efi can and dbc

Yes, on Linux, Raspberry Pi OS latest. Rpi 5 16gb. Two SocketCAN inputs. One from Holley and one from BMW K-Can (for car stuff like fuel level, etc). Works perfectly and very smooth.

I haven’t had a chance to go out and test without the BaseId. I’ll try it. I can’t remember if I did.

So I did two tests:

  1. Using the built in Holley: HP Dominator & Terminator x selection in the garage —> works just choosing it and seems to mask the bits for the baseId.

  2. used the xml file from Github dominator_and_terminator_x_can.xml → works fine without baseId.

So this confirms it is masking the baseId bits correctly. Sorry for the confusion.

Alright, thank you for verifying this. I also tested on simulator and it was masking the CAN id correctly.

So, to expand this a bit more. Could we start writing messages back to the holley on the canbus? I believe you can use the prodash button setting in the software.

Sure, as there is working CAN connection, you can also send CAN frames from RealDash to Holley. There are multiple options:

  • Use ‘Send CAN Frame’ action to send a static frame.
  • Describe your custom CAN frames that are sent by RealDash in your XML file. Then make a button or trigger to change the value that is in XML file. When value changes, its associated CAN frame is automatically written to CAN bus.
  • You can also use ‘writeInterval’ attribute on your custom frames to periodically send the values from RealDash to CAN device.
