PID 3 is the voltage index for the dwell table lookup. So 5 would be correct for the 12v column. If you want to see actual sensed voltage add a 'V' to your logging request. Just bear in mind asking for a lot of human readable conversions on the logging data adds cpu load.

Temperature sensing relies on seeing initial spark advance to know which voltage divider the ecu is using so you'll need to at least attempt to start before it knows what lookup table to use. Did you copy your crank spark advance table from 12075 into the definition of crankSpkTable in config.h?
