It seems the the 105 kPa table in each B0101 and A0009 are averages of the entire row of the opposing table. not accurate BEN at all. Is this a bug?

The way the table interpolation works in the PCM is like so.
If the MAP is reading 102kPa, then the PCM will average out the VE values between 100kPa and 105kPa, if the MAP was reading 104.95kPa, the PCM will still look between 100kPa and 105kPa, this of course is the range of the standard VE table.
Once you go above 105kPa then the boost VE table comes into play, so any MAP value between 105.01kPa and 110kPa the VE value will be the average between the numbers in 105kPa (boost VE) and 115kPa.
I think because both are labeled as 105kPa it looks a bit confusing, but it would look 'dumb' IMHO if we had 104.9kPa as a column label.
I understand your confusion, but does that make sense?.

I understand the interpolation. What I see is my MainVE tables go from 85 in 95kPa to 69 in 105kPa which is fishy and I dont trust it for BEN tuning. In {A0009} the 105 kPa colum shows a cumlative cell count for MainVE table so I dont trust that for anything either. I have to get the laptop out of the car to be more specific but it seems to me that the 105kPa tables on both B0101 and A0009 are "junk" values derived from the contents of the other table and that you need to linerally scale across that boundry.

85 in 95kPa to 69 in 105kPa does not seem right to me either.
I understand now what you mean with the two 105kPa columns in two different tables.
What you could do on your log is using the filtering on the BEN MAP so that if you are working with the std VE table you can filter any values below 105kPa and the opposite for the boost table, see if that pulls your numbers back in place.

guess thats what those filters are for... :P

Are you using separate BEN maps for normal and boost? I tried that and got strange results. Doing it all in one map seems to work fine.

yeah I have two maps defined. how do you get two tables in one?

Change the MAP scale to read up to whatever boost u are running?
Thats what I have have done have'nt tested it on a blown car yet but it should work

I thought I tried that...

I just created one BEN map table using the kPa values from the two VE tables. When I copy and paste in BEN values, the regular VE gets 15 thru 105 and the boosted VE gets 105 and up.
