Logging sensors through ODB
#6
I think requested RP has a good chance of being a value stored in a real address in the ECU data that other OBD values are referenced from...

I'm far from an expert on it all but I think OBD coverage is just a list of values exposed under the OBD standard (possibly headers on the values in the memory that OBD kit can scan and find!?)
It's likely that you can also just manually enter an address and get the value.

Ie, years ago a friend used to play Command and Conquer on LAN and he used to monitor money values in real time after finding the correct address, and often changed his money value haha... often we got sync errors in the game and it'd crash out, but I *think* OBD is just a set of advertised addresses, but in theory can enter it's own and look at other stuff.


OBD is still not that fast though...


If you can do one variable by OBD and then another via multi-meter logging you can combine in Excel later and get better performance from both. Ie, just one PID via OBD is maybe 5 samples a second which is pretty good... add one more and you get half speed, and so on.
