CAN-EGT 8 channel thermocouple interface

[kb1gtt]

I've had luck with this PCB screw terminal. http://octopart.com/7693-keystone-116638 It's about $.50 each, perhaps that's to high of a price, but they are reasonably rugged. I've never used them in QTY, but they worked well on a prototype.

didn't get it. does this mean that the egt unit might just be sending out, say, each 50ms couple of messages, say with can ids 0x98 and x99 with temperature values for the eight cylinders, and should there be any other device on the bus sending out can messages with same can ids, the ecu would get confused?

It is of engineer responsibility to assign unique IDs on the bus to approp. ecu. EGT ecu will send 0x98 and 0x99 messages and no one else.
There should not be any other source for such msg.
PCM as receiver of such messages is not able to recognise which ecu is transmitter of such msg. CAN itself does not have system of something like address of transmitter and receiver (like in OBDII (on ISO bus) protocol is, for example).
CAN frame has only ID + 8bytes of data. Nothing more.

kb1gtt: no, I am not the person.

About ISO15765, that seems like a good option, as it will probably be desired else where, for interfacing with off the shelf diagnostic equipment. The goal will of course to be only to use the MFG codes, and such to keep things legal friendly. ...

Don't know about legality of using iSO15765. I hope it does not have any royalties or so.
Using ISO15765 would have benefit in every phone/tablet/PC+ELM327 will have possibility to read DTCs from RusEfi
and in addition there would be used applications like Torque for live data monitor, ....

Above the CPU and headers is the jack for the CAN bus. This is a 3.5mm jack that is compatible with the USB-CAN adapter plug

Is there a de-facto pinout of using 3.5mm plug for CAN?
