You need to determine all the values through trial and error.
disable boost control, test, write down the level of boost it logs. 0% duty cycle = this boost level.
enable boost control, use fixed duty cycle, set to 10% duty cycle, test, write down boost level it logs. 10% duty cycle = this boost level.
set fixed duty cycle to 15%, test, write down boost level it logs...
repeat this process in increments of 5%. After you have tested for all increments until you hit your target boost, enter the values that you wrote down into the duty cycle vs pressure table.

Hello,
so here, I set the frequency on 35 hz then I increased the duty of 1% in 1% because 5% in 5% it was too much.
here are the results:
IAT at 5-6 ° C, sensor before throttle (7am)
outside temperature 1 ° C
20% 1.32 bars
21% 1,36 bars
22% 1.41 bars
23% 1,50 bars
24% 1.51  Bars
25% 1,60 bars
26% 1.65 bars
27% 1.67 bars
28% 1.75 bars
29% 1,80 bar
30% 1,85 bars
31% 1.92 bars
32% 1.93 bars
33% 2.04 bars
34% 1.94 bars
35% 2.09 bars
36% 2.17 bars
37% 2.23 bars
38% 2.30 bars
39% 2,34 bars
40% 2.41 bars
41% 2.54 bar
42% 2.64 bars
43% 2.73 bars
44% 2.84 bars

IAT at 30-35 ° C, sensor on intake manifold (1pm)
outside temperature 12 ° C
20% 1.32 bars
21% 1,38 bars
22% 1.41 bars
24% 1.49 bar
26% 1,59 bars
30% 1,70 bars
29% 1.65 bars
31% 1.75 bars
33% 1,88 bars
34% 2.04 bars
35% 2.02 bars
26% 2.17 bars
37% 2.21 bars
38% 2.21 bars
39% 2.24 bars
40% 2,32 bars
41% 2.52 bars

what values ​​should I put in the table knowing that there are not many boxes?
then IAT I keep what? manifold or piping before the throttle?
Is it better that I increase the frequency to decrease the duty?
Thanks for your help

Enter the values for the ranges you want to be able to target. See if the default temp compensation works with the values you enter.

I want to target between 0.5 bar and 1.7 bar boost but it's a lot of values for the case can

IT will interpolate between the gaps in values, just choose some high ones and low ones and some in the middle.
