Can anyone point me to a how to on using vecalc in tunerpro? I would like to log a drive then use vecalc to make bulk changes to my ve table based on target afr and wideband data.

Is there a write up in the faq or tuning guides? I can't find it but I may also be blind.

Thanks

use the histogram function when playing back a log and record running average. note that vecalc especially cells with few samples can be inaccurate due to measurement time applying the calc to nearby but incorrect cells and enrichment / enleanment. once you've got calculated changes your still best off modifying the ve by hand to average out the results and filter out any cells that look wrong. you can select many cells at once and add or subtract some number over a whole area then smoothe in the edges by hand to apply these changes in a measured way instead of every cell one by one. you can also take a similar approach by overlaying target afr and wide band afr in the monitors, too, then looking for what region varies the most and apply corrections there. bubble tracing will show you what area when you click a point in the log and have the ve table visible.
