This is why I was so incredibly confused with why GM structured their tables this way.
    Just to more completely explain my position on this, temperature and voltage are variables that primarily (in the case of voltage, strictly) impact the coil's electro-mechancial performance. Another way to explain this is that voltage and temperature are more analogous to environmental parameters. They don't generally change in rapid and direct correlation to instantaneous changes in overall system condition. Relate these to the ecu's barometric corrections.

    I chose to use RPM and MAP for the axes of the multiplier table because neither of these directly correlate to a coil's electro-mechanical performance. They're resultant and / or situational parameters that are intended to be used to adjust spark strength to the engine's current power demand / production metrics.
