Ok so I switched to a normally closed solenoid. I changed my solenoid configuration in Kpro but did not change my vacuum line configuration. I am currently running a vac line to the side of my TiAL 44mm gate and the boost controller line to the top of the gate. So to achieve the same boost level as I did with the open solenoid I set my fixed duty cycle to 85% where it was 15% before. Does this sound right? Should the vac lines be setup differently?
Also, if this is correct then trying to setup up boost vs gear is a bit confusing because it will no allow me to enter duty cycles in a decending order as boost ascends. In other words it will not let me do this for example:

Yes I am aware of that. This is exactly what I am attempting to do. However If my thinking in the first paragraph is correct then the duty cycles would have to be in a descending order because higher duty cycle equals less boost. However the table does not allow this. It will only allow me to enter boost and duty in an ascending order.
what solenoid do you have? I have the perrin and currently have all boost control turned off as I am running straight off the gate. I am trying to learn more about boost by gear and how it works.
trying to find if the perrin is a normally open or closed unit and if when doing boost by gear if you can just input the boost psi you want and leave the duty % alone or how I can figure out how to do this.

I have the perrin. It is a normally closed unit. To use boost by gear you have to determine what duty cycle gives you what psi. To do this you have to set fixed duty cycle and keep changing it so you can determine this. Doing this will allow you to create the table. Im having a bit of trouble with this.

I dont get it.
Answer me this though. With the gm (open) 15% percent duty cycle would get me 15 psi and any higher duty cycle value will increase boost. Now with the perrin (closed) 85% gets me 15 psi and any lower duty cycle will increase boost. Is this normal??
Ok now if the answer to the above question is YES then essentially my boost by gear table will be reversed however kpro doesnt let me arrange duty cycle in decending order.
There is an option there to choose the solenoid configuration (open or closed). This selection automatically inverts it so that you can use the table with ascending values.

See whats weird is that when I select closed the higher the duty cycle the less boost it will create. As if the values aren't being inverted. Does this inversion only work for gear based and not fixed?
