I am trying to tune the VVE table on my 2015 Silverado and having some massive numbers generated when I click the claculate coefficients button.
I am logging AFR error with my wideband, I copied and paste special by% and everything looks great until I click the calculate coefficients button. The cells around the 23 zones are all in the 2000 range but those two zones are over 55000.
If I change the cell hits in the histogram around and try again, it will be fine so it seems the math is doing something crazy there. I can get it to mess up the zones around it as well.
Any ideas on how to fix this issue, what I am doing wrong or just use the higher cell count from the histogram when pasting?
I started using 50 cell hits but it seems that 300 or higher eliminates this issue. It was a 2 hour log, so I have quite a few cells populated even at 300 so I can make it work. I was just curious as if anyone had this issue and I didn't find much from the search button.
I copied the labels from the tune VVE table and the zones are all stock. I used AFR error with engine speed vs. MAP/Baro ratio for the histogram.
Any help is appreciated. I am just learning so I have a long ways to go. I have the MAF logging less than =/-3% error and now i'm trying to work on the VVE and hit a road block with this issue.
