Xtreme Vs Challenger Fuel pressure Option

Gidday everyone...

I have an Xtreme and a Challenger. I'm trying to setup both Efis with the Rdac Xf.
The one sensor I'm having issues with is the Fuel Pressure, the sensor being a UMA 2 BAR I was able
on the Xtreme by picking TYPE (resistive) SENDER (vdo) MODEL (2bar) to work properly.

On the Challenger the options for the fuel pressure are not the same :roll:
The closer I can get is by picking the automotive(resistive) but the option for the probe
resistance are 150 or 200 Ohms that are the closest to mine(180 ohm).

So at 0 PSI. on the challenger I'm reading 0.6 PSI and I've turned my boost pump (no engine running)
and the Xtreme is giving me 3 PSI and the Challenger 1.7 PSI.

Any suggestion??? as I would like to have the proper info on my Challenger.

Regards
