Default Zeitronix datalogging and MAP voltage.

I have a d16z6 with a T3 turbocharger, crome tuned.

I am trying to figure out how to scale my map voltage to figure out which vac/boost tables to tune.
Yes it is hooked up correctly. I am using the user1 input hooked up to read map sensor voltage.

Around 18/17" of vac I am getting anywhere from .35-.47 volts

I am still running a basemap so at my current max (4psi) boost I am getting around 4.83-5.0 volts.

I was under the impression that I wouldn`t see 5v map until the map maxes out under boost (about 11.2psi)....so wtf??

Anyone out there know how to scale map voltage to vac/boost tables? I am thinking I should just man up and buy the zeitronix boost sensor...I`d like to find a way around that if possible since I`m a cheapass broke nukka.

I've got the map sensor wired to the User1 input but it seems to read really low like 4 to 5.5 lbs when im boosting 8lbs.

Datalog with ECU control to know for sure
