or commonly rounded to 14.7psi at sea level = atmo
but actually atmo changes depending on location.
so no atmo does not equal a bar.

WOT can also change depending on location as well

The RX-8 baro sensor essentially senses atmospheric pressure and is really more of a crude altitude detector with no weather correction input. The baro = zero column would be considered ideal sea level conditions. The negative baro value columns are decreasing altitude (below sea level) and the positive baro value columns indicate increasing altitude. The baro sensor itself is a 0-5 V output device with CEL faults if it drops below 0.2 V or exceeds 4.8 V and the expected sea level output is 3.8-4.2 V, but again this can vary due to atmospheric weather conditions. So the Cobb Accessport map shown below is setup as a reversed V output differential from sea level rather than the direct baro output. Can't really say why that is ...

HTHs .....

The yellow injector is the secondary injector. (lower table)
