Blocks IDs that are almost certainly irrelevant to EPS assist function: VIN, MFL buttons, diagnostics/ISO-TP, DME temps+fuel, cluster warning-lamp broadcast, and other modules' generic status heartbeats (not 0x4B0/0x1FB - those are the EPS's OWN transmissions, confirmed on the isolated bus, not something the car needs to send it). Everything else stays allowed until tested. See eps-comms/findings.md.",
