Holley Dominator CAN Setup on PDM25+ V1. v1.15

Trying to get Holley Dominator CAN data working on an older Hardwire PDM25+ V1. Firmware 1.15


The newer PDM28 imports the Holley DBC fine, but the older PDM25 software doesn’t have a Float data option.


I know this has been done before. Does anyone have the correct setup or an old Holley/PDM25 configuration they can share?


Mainly trying to get RPM, MAP, TPS, coolant temp, etc. working over CAN.
