I used the boost target info I found in the RAX PDF (but it's not in the XML...). Perhaps I put it in wrong because I'm always getting 0.967 for boost target... That can't be right. Can anyone help?
Okay, so now I've swapped out my OMNI sensor for a new one and I get the same exact readings. I notice that with the ignition on (car not running) it reads less than atmospheric pressure so the sensor scaling is off. I went ahead and did a test and tabulated my Zeitronix gauge data against Evoscan data. See attached screenshot of my spreadsheet, it looks like a linear offset all the way up to 26psi. How do I fix this? I suspect it's my X-axis scaling on my MAP based load calcs tables? I've also attached a screenshot of those. I attached a screenshot of Tuner Helper's screen too because it tips me off that I should be looking for an X-axis scaling that ends with 34.98, but I don't have any scaling in my XML that gets me there... I'm expecting a scaling like "Omni4barMAP in psig" but I don't have any such scaling.
Hi, I download your ROM and had a look. It seems you missed out 2 additional steps in enabling the Omni4Bar usage. You enabled the 3 patches but missed out the X axis changes for the MAP based Load Calc and Fuel Compensation MAT vs MAP tables.

You're amazing, thank you! I tried several times to start from scratch and change the X axes like Tephra says in the thread here: https://www.evolutionm.net/forums/ev...r-writeup.html but when I do the car runs terribly. Attached is my restarted Tephra V3 ROM where I tried to follow the rescaling directions. Below is a screenshot of my current ROM on the left and my restarted ROM on the right comparing my map based load calc tables. Car ran super lean on the restarted (right) maps. I think I could use a nice clear walkthrough on how to do this considering I'm using Tephra V3, RAX, and Spark Cut. I don't do this as often as I used to so I must have lost my edge.
It seems like your axis are still wrong. Probably didn't have the right scalings in your definition files.
Maybe you can PM me with your email address and I will send you the modified ROM to flash and test.

Great, thanks! I'll do just that. For any in the future, if I get resolution I'll post up my files on this thread.
Anyone know how to make the units jive between ECUFlash and Tuner Helper? Tuner helper appears to be in PSIG whereas my "Omni4barMAP in kPa" scaling is in kPa absolute.
Wait, I stumbled on something. HERE I found that Tuner Helper must be using "stockXmap in psig" scaling. When I use that scaling in ecuflash the tables line up.
