FreeScan MAP values??

I was wondering what the Values in Freescan under the MAP column refer to.
At WOT none of mine go over .97...it this normal.
I was thinking that since my bar reading was only going to 1.02 that it would basically be the MAP value in KPA but I just want to make sure.
Thanks

Looks like they are showing BAR and MAP in kPa, but erroneously including a decimal point. 102kPa would not be unusual for BAR near sea level. And 97kPa would not be unusual for MAP at WOT, max air flow. The difference represents the pressure losses in you air inlet track..... filter, ducting, MAF, etc. Remove the filter and you should see a slight increase in MAP.
