EQ error log not populating.

Hi all
My truck is 2018 GMC Sierra Denali 1500 6.2 gas
I'm trying to make a graph with the same row and column as my virtual VE table.I used user math to make up the map/barometric pressure ratio. I dunno for sure where I've made a wrong turn but it looks okay to me but no matter what I've tried I can't get my graph to populate. The graph's that are so with the template I choose seem to update fine. Hopefully someone can help me see where I went wrong?

First pic is my VE table in trying to replicat.
Second pic is my VE scanner page.
Third pic is the math parameters I made and used.
Fourth pic is the graph settings I used.
fifth pic shows the greyed out ratio channel's that i need for this to work but they disappear when i hit start scan.
I have a MPVI3
And I've tried closing the program and restarting it and disconnecting and reconnecting the MPVI3.
any hel getting my WB error ratio working I'm open to listen.
Thanks to anyone who tries ��

your graph is looking for two MATHS, you're only showing one. you will need your "EQ Ratio" math... 2 cents, only been here a couple weeks, best of luck!

Yes I understand what you are saying. But what I'm saying is I have no option for WB ratio. The two that are in the 5th picture shows them greyed out. I don't see anything for WB ratio at all for the stock sensors. My truck is 100% stock.

From what I think I see is that the gen 5 gm vehicles don't use wide band sensors so my EQ ratio prolly isn't gonna work with these settings because I don't have wide band just stock low bands sensors.
At least that's what I'm thinking is going on.

GM uses Narrow Band sensors.

People add Wide Band sensors for WOT tuning or curiosity.

Thank you I understand now why my graph wont work.
