HKS EVC V Kpa to Psi Value set

[GST-RIDER 95]

I just installed my EVC V and no where in the user's manual does it say how to switch the displayed boost value from Kpa (bar) over to Psi.
This is a used controller that I got from a friend who had it in his car I asked him if He knew how to switch it, but He was unable to provide me with an educated awnser.
I feel it is a lot easier for me to adjust by Psi than Bar.
Please advice

Unfortunately HKS made 2 different screens one in bar and the other psi but they don't do both. so you can only do bar with the one you have.
