This has changed recently. Latest S6 firmware allows Life Racing, Syvecs or JTi GPS receivers to send full GPS data on the same CANbus that's running the slave. You can also send CAN EGT data in on the same bus - either Syvecs or (soon to be launched) JTi versions.TimH wrote:You CANNOT have I/O assigned to a slave, AND have GPS receive enabled. It's nothing to do with terminations, connections, or whatever - the ECU will complain as the config is invalid. The single CANbus cannot support both.
It's a shame that this is not clearer from Syvecs/Plex.
JTi expander (will soon) support wheel speed data using the Bosch M4 ABS protocol, so you can get the benefit of GPS, and 4 additional inputs (albeit only wheel speeds) all on the standard 1Mbit/s CAN.
The Plex can receive dash data on a slave link (1.33Mbit/s CAN) but you would not be able to send CAL up/down messages back in. The X10 also translates the outgoing 1.33Mbit/s generic transmit datastream from the S6 to 1Mbit/s allowing all other devices (e.g. Toucan) to receive data. It is data back in to the S6 that is limited in this scenario to: slave data; GPS; EGT.
Bottom line - your S6 and an expander, plus a GPS unit, could all have been made to work.
That said, an S8 is a nice bit of kit
