I tuned a 2006 H2 yesterday. I started tuning the VE with fuel trims and then switched to my wideband to compare. I bstarted with a stock VE table both times. Why is there a difference in the direction the VE table gets adjusted between fuel trims and wideband tuning? Seems like the fuel trims made mountains while the wideband made valleys.
Here is the stock VE table
