Safc and FCD

I was just wondering how would i bypass my fcd to actually get a correct pressure reading on my Safc.

hmm..... if i remember correctly the fcd modifies the signal coming out of the pressure sensor, and sends a clamped signal to the ECU,

im guessing your SAFC has the pressure input signal tap by the ecu? if you tap your signal from after the pressure sensor but before the FCD it would probably read the correct voltage and correct pressure! i think....
