Hi Mark, So, following the "OVMS issue: obdii on can3 crashes VMS" thread on TMC led me to an "oops!", I think... Did I miss something? With the updated OVMS cable to the Diag port on the Roadster, the report is that all 3 CAN busses are connected to the car. If so, doesn't that make the obd2ecu process impossible to run, since there's no CAN bus available on the 26 pin port to connect a HUD to? And, if one were to hook up a HUD to the 26 pin port, wouldn't its polls be sent on (at 500 kb/s) through the OVMS wiring to the car, confusing the car? Is the older (single CAN bus) cable still available? That, I would think, would fix the problem. I have the original cable, so haven't noticed anything wrong. The OP on that thread also claimed the original cable, which doesn't make sense. Where is the Oops? Greg
