The canbus is the data stream into and out of the ECU. The Procede reads that. If the factory ECU doesn't see it neither does the Procede unless it's specifically added to the Procede harness (like alcohol injection or map switching). That does not necessarily mean if the ECU sees it the Procede does though.
