Refer to my reply #8. " Change the drop down box on the left to manifold switch to open."

Tried it on switch open, same thing. Must be some kind of garbage in there somewhere. Have no idea how it's getting -11,000 to 14,000 in the 3 columns. Going to try a re-scan tomorrow and see what happens. Just started raining..........

it does that sometimes, just smooth the error out and go again.
I just brought them closer to the surrounding cells and hit calculate. Looking at it in 3D it looks choppy as hell, but checking the original it does too. Looking at the diagnostics--->airfow tab and failing the MAF, it seems logical to me to get the P0101,P0106 and P0121 out of the way and disable Cat testing??

Ok i must be doing something wrong but i cant figure out what i missed. If someone could take a look. I have my MAF failed according to what i have read here and have done it dozens of time on my E38 but I am not getting the code set or light. Did not realize this till after 2 scans. I'm guessing that is why when i make adjustments to my VVE table, nothing changes in the cells much but my trims are increasing. I'm sure it's something simple that i have missed. I did the first scan, copied and paste special----multiply by%-1/2 claculate both open and closed then save. Upload to the ECM then drive/scan and as you can see almost no difference.
There must also be a bug in the programming, every time i do a calculate, i get some outrageous numbers in a few cells.
What am i missing in the setup??

I am still new to tuning but I did my 2014 chevy ss using histgram for rpm and map set up the save way the VVE looks. I am trying to tune my friends 2017 Camaro SS and everything is so different to what i was learning on. I thought the vve was stating a math. On the scanner I added the marometric pressure to the list and then I made a new math paramer of MAP/barometric pressure. i figured the output of that parameter was the ratio it needed so this is very helpful, thank you! I knew it was a whole different thing to tune vve for his car just didnt know how to get it. Also the OP posted the MAF in the scanner with a lot more cells, i just have the one row that matches the maf on the tuner app.
