Not meaning to hijack the OP's thread but I need clarifying on reading fuel trims (which may also help OP understand more about reading logs). From a graphical standpoint, its the lower the line the better? smoothness? I can't tell what is good from bad. Again, I'm strictly talking about the "trims" variable.
I notice that the OP's graph where e85 shows the fuel trims to be near the top of the graph when the 1st/2nd are lower and it spikes differently.
Thanks.
