Freescan Question...MAP readings

I am reading my MAP on freescan, and trying to tune with TunerCat. Looking at my Freescan it doesnt show what units its in. Looking in TunerCat it wants the MAP pressures in kPa... Does .45(in freescan) = 45kPa in TunerCat? And also, if you are at .67 MAP does it pull off the 65kPa MAP or the 70 kPa MAP?

I am doing some partial MAP tuning and this is what I am using to pull some timing, we will see if the knock goes away.

Yes, the .45 would be for the 45kpa range. I believe if your at a .67, it will use the 65kpa cell. Someone correct me if i'm wrong....

thank you very much, the info made me feel a little better about partial map tuning.
