Will engine braking taint log data? I'm working on my VE table after installing a Trex. I noticed when I was logging last night (watching LTFT's) that if I let the car coast in gear (m6 car) the LTFT's would go to the lean side in that particular cell. It looks like it may be causing inacurate readings in those cells. Is it? Because if I adjust my VE table with this data it causes peaks and vallys on the VE table in the areas that I let it coast in.

As designed. It may well be the dfco cutting in.
You can filter it out by only looking at data over 3% tps or whatever your dfco trigger is.
VE should be smooth like a rolling valley. Any cliff faces should be blasted off by checking filters and/or smooth functions.
