Re: For Configuring the MAP sensor
For the HFS4-v2, 2.5bar is the default factory setting. It will read up to ~22.5psi over 1 ATMOS.
Your setting should be B (default). It translates your sensor from 1.88-4.76V to 0-5V for the internal circuitry.
The difference between a,b and c is the voltage at 1 atmosphere. It is used internally as a boost reference from 1 atmosphere.
