Default Help Tuning AEM 3.5 bar Map Sensor

Last thing I need to do to get my car up and running is to scale the map sensor and of course it want s to be difficult.

After over a week of searching I figure I need to ask my subie brethren.

I have an 06 forester and Im trying to scale the map sensor with ye old accesstuner race software.

The problem Im having is that the numbers simply don't add up. Here are the stock calibrations:




Im trying to input these values which I found posted by other forum members to be the correct scaling:
Multiplier = 12.6875
Offset = -6.34375

But once input the highest it will go is to this:
Multiplier = 1.379
Offset = -1.379

Am I looking at the wrong option within the software or do I need to convert these values to a different format?

Thanks in advance for any help.

By the way Ive contacted a tuner which I will not name to avoid ruining a rep and for some reason even after several attempts even offering to pay in advance I can seem to get a response to get a break in map so that's why Im trying to do this myself to get it going to the point I can get the car running to get it to a shop for proper tuning.

Oops I now realize my issue!

The Multiplier and offset values I have are in PSI and the entry on ATR is in Bar.

So for anyone doing the same and don't want to make my mistake the values in Bar are as follows:

Multiplier = 0.874
Offset = -0.437
