Graph filtering

I ave been tuning my 2 door tahoe on speed density only and using an eq ratio off my wideband to tune the ve. I have got most of the cruising areas dialed in to less than 1% ratio error. My question is how can i add filtering in to clear out anything +/- 1%. I have tried the less than/more than method and its not clearing out what I want. Thanks in advance.

Dump it into excel and make adjustable filters to remove the data above/below a certain amount. Then copy those results out of excel to put back into Editor.

Ill do that. Thank you.
