Not sure who may need this, but this is a handy little chart to help you convert your MAP sensor voltage to PSI (with 14.7psi atmosphere already subtracted). The actual atmospheric pressure varies by sea level, just keep that in mind. Useful when datalogging or when using a scan tool to watch live data:


Voltage​
Boost Pressure​
2.16​
1.15​
2.35​
1.89​
2.55​
4.63​
2.74​
6.37​
2.94​
8.11​
3.13​
9.85​
3.33​
11.59​
3.52​
13.33​
3.72​
15.07​
3.91​
16.81​
4.11​
18.55​

22.03​
4.695​
23.77​

25.51​

Mapped this on my V2 years ago (remember my Boost-F'er-Upper?) and the numbers FR posted are pretty much identical; probably +/- ~0.05v

So even electronically regulated the numbers are the same.

Odds are its the same sensor with the bolt offset changed slightly. The electronics are visually the same and they are the same diameter and use the same o-ring.
