Question omni 4 bar setup?

Im in need of a little help guys, Setting up this Omni 4 bar on rom id 55570006 is kicking my butt! LOL I started with a tephra xmod rom for this 2010 X.
I installed the 4 bar map sensor and changed the settings under "Omni 4 bar boost" to the correct settings for Omni 4 bar. With the key on, engine off, im seeing -2.4 psi via evo scan mode23 logging.

So my question is, did I setup the sensor correctly in the rom? Or is my evoscan logging incorrect?

Thanks so much for the help guys!

I read this thread, it doesn't have the coding I need for my rom id but has all the other info when changing map sensors. Thanks again.

You should try RAX Patch v2 logging.
https://www.evolutionm.net/forums/ec...m-patches.html

Once you figure that out, you can edit the MAP to adjust for the 4Bar MAP sensor right in EvoScan 2.9.xxx (newest version). Simply right click on MAP, edit, input new values. I like to also edit the notes to save 3Bar and 4Bar settings so I can just copy and paste.

Omni4Bar MAP Sensor.

Eval (PSIG) = [RAX_D_Dat]BITS(32,9)*0.11715
MetricEval (kPa) = [RAX_D_Dat]BITS(32,9)*0.8077214

Thanks GSXRider! Im still confused in one area. Im following you on the logging part but not on the actual tune side. Do I not scale the 4 bar map sensor in the tune itself first? Or that's not needed?

This is the final piece of the puzzle for you. Just select the 4Bar setting in the drop down menu of the application.
