Theres not a lot of info around for what filters people use while doing their AutoVe tuning.
Would you care to post up what filters your using and why?

the auto ve tutorial helps you set up the filters you need one for temp. and one for tps

KR more than 0.00
TP is less than 2.00
TP is changing more than 5% per 100ms
ECT is less than 63 degC
Once I have applied this filter I would check the IAT & ect that is most common & add the temps that are out of range to the filter.
From then on all adjustments to the ve table are made with that filter applied to make sure transient temps arent messing with the data.

This is kind of old but how do you know if the filter is applied or not? There is a button apply or remove filter but after you hit it and every thing is changed it doesnt say if it applied it or removed it.

btw don`t filter out your KR if you are hitting it because of lean you may miss some data spots
or if you timing is to far advanced paste and subtract.
also if you filter TPS less than 2% you will hide the low kPa cells.
my 2 cents.

I had to change my coolant filter also cause I have a 160 deg stat now.

There is two sides to that coin. KR can cause the lean reading so the data you use could be bad. Better to filter it out of your main data & have a look at why later.
As for filtering throttle under 2%. By lifting your foot completely from the throttle while decellerating you will let the filter remove transients from this condition.
