A method for WUE tuning
This is just to make sure that what I'm doing is sane and perhaps give other people some ideas.
In order to tune WUE, I'm using MegaLogViewer. I've created a custom field: 100*[AFR]/[AFR Target 1]. On a scatter plot, I map it against CLT and use hits on the Z axis.
To find out how to adjust the WUE table in TunerStudio, I check where the plots are at each temperature that I have on my WUE curve. The plots can be a bit fuzzy, so use the colours (number of hits) to evaluate the weight of the plotted data.
Say the custom field value is 95 at 0 degrees Celsius (slightly rich), I multiply the WUE % by 0.95. So far it has been a breeze to get the AFR to match the AFR Target through the temperature range. Below is my current WUE table. It is tuned down to 0 degrees and below that point it's a best guess.
Obviously, in order for all of this to have any meaning, a well tuned fuel table is essential.
