log boost with JDM MAP sensor (updated instructions)

Okay, after some messing around with EvoScan I'm now reading -6.38 boost (vacuum) with the car off. The formula I'm using is 0.19347*x-14.7. I'm in San Diego so I'm at sea level. I could use some help. Are the settings for the Omni 7 bar the same as the 4 bar? I'm editing the Mitsubishi MUTII EFI.xml file found in EvoScan v2.9-->Data Settings. Is this the xml file I'm supposed to be editing for a 03 VIII. I'm using the 94170008 rom. Thanks for any help that comes my way.

So after a few minutes of messing around with EvoScan I was able to log -.0008 boost with the car off. But that was after I changed the formula from 0.19347*x-14.7 to 0.19347*x-8.32. That's okay with me until someone tells me otherwise. But when I log at idle I'm only reading -2.9- -2.7 boost. I'd love for someone to let me know what I'm doing wrong.

Thanks for the suggestion. I'll do that tonight at work. Do those wires go directly to the MAP sensor? I'd imagine I'd be able to meter at the sensor itself since those pins are simply power and ground for various 5v sensors. Fortunately this is my area of expertise hence the username. I'll look in the wiring diagram. Though I don't believe it's a power distribution problem, it wouldn't hurt to check it anyways.

I've been searching around for a while now and can't seem to find the map sensor definition tables for my JDM IX MR...80920002 (inherits 88570008)
I just installed an Omni 4 bar and am unable to rescale it because the tables aren't defined. Thanks for the help in advance guys.
