Is anyone aware if the analog signal provided by the AEM Digital Boost Gauge provides an absolute pressure. ie. atmospheric pressure plus the pressure created by the supercharger/turbo etc?
If this is correct I am at or around sea level so I have an approximate atmospheric pressure of 14.7 psi.
If this is the case I would need to modify the formula applied to the raw 0-5 volts from the AEM boost gauge to be "[(12.5*v)-6.25]-14.7". Anyhow applying this formula the boost levels I am datalogging appear significantly more accurate.
Can anyone confirm if this correction for atmospheric pressure is required?
