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

Here are a couple screen shots to get you going.

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.

I need help figuring out why my evoscan is logging much higher boost than is actually there. I'm using Tephra V3 for my X with RAX. I've zeroed my WGDC/boost tables and my Zeitronix gauge, logged load, and perceived power (butt dyno) all agree that I'm at wastegate pressure of only 19ish PSI... but per below you can see that Evoscan is saying I'm at 32PSI. Please see below my screenshots, including my scaling for the boost. I've also included a screenshot of my ecuflash ROM showing I have it all enabled. Do I have to "scale" my MAP or something? I've only had this issue recently when I realized I had a bad boost leak... I fixed it and then had way high boost an so I zeroed out my WGDC/boost tables to start from scratch and I noticed this discrepancy. Any ideas?

Any specific reason you went with a 4bar sensor? Are you really wanting to read past 32psi?

https://www.evolutionm.net/forums/ev...r-writeup.html

A summary:
In standard EcuFlash definitions, you need to:
- take the X-axis scale values from MAP based Load Calc #3 and paste them into #2
- take the X-axis scale values from Fuel Compensation MAT vs MAP - Omni4bar and paste them into - Stock3bar
- revert 3x values under Omni 4 Bar Boost back to factory
- if using PSI-based boost target, copy Boost Target 3x tables from Omni 4 Bar Boost section into Direct Boost section
- also, copy OBTR Y-axis from and to the same
- also, copy Target Boost Error Correction from and to the same

Thank you so much! Yes, I run about 32psi right now, no idea what I did to screw this up when I went to V3... I do this so infrequently now that I find myself having to relearn all this. I have some questions:
  • You say take "Map based load calc #3" x-axis and put into #2, but Tephra says to copy #1 and put it into #2.
    • Which should I do? Screenshot below.
  • You say to "revert 3x values"... what does that mean? I read and re-read this and don't know what you mean.
  • I am using the PSI-based boost target - what do you mean when you say to "Copy them" from the Omni section to the direct boost section? You mean copy the values in the tables
    • I think your next two bullets appear to be similar so I think I can figure those out if you explain this maybe.
For ease, here is my ROM and definitions in a zip if you care to look: https://drive.google.com/file/d/1IQ8...ew?usp=sharing

Hiya.

For Omni 4-bar logging in EvoScan using RAX Fast Logging, try revising the formula to...

MAP imperial: [RAX_D_Dat]BITS(32,9)*0.11715
MAP metric is: [RAX_D_Dat]BITS(32,9)*0.8077214

Thanks for the input Rich! Indeed, that's the formulae I'm using per my screenshot above. Any other ideas?

I did go through and follow the directions in that link posted by METAL_AF and I'm still seeing basically pegged boost in evoscan (~32psi) but I know I'm only running about 19psi.

Okay, I see it.

Your EvoScan "RAX Fast Logging" Boost item should simply be as follows...

[Map]-[Baro]

...whereas you have an actual calculation in there.


So... Make sure your MAP is reading correctly. Make sure your Baro is reading correctly. Your "gauge" boost is simply one minus the other.

Rich

PS. It looks like you're also missing Boost Target as a logging item. See if you can get that one back, as it's useful!

PPS. See if your logging works faster if you disable EvoScan's "multithreading" mode. Go to "Files" menu and TICK "Disable MultiThreading".
