=== Map for boost pressure actuator setpoint ===
More commonly known as... wastegate duty cycle (though it's the reverse).

TBDFIRST PASS, NEED MORE DATA TO CONFIRM: The way the wastegate duty cycle works is based on modeled turbocharger tables that calculate the turbine intake and exhaust flow factors. It's *impossible* to tune the wgdc on an ED tune without additional logging capability. One possible way to tune the wgdc is to measure the following 4 variables:```fac_1_put_ad - first parameter for precontrol and adaptationfac_2_put_ad - second parameter for precontrol and adaptationfac_pow_put_ctl_opl - Open loop value of PUT controlfac_pow_put_ctl_rgl - Regular value for PUT control```In maestro, the axes are labeled incorrectly.The X value is *actually* `fac_2_put_ad`, and the Y value is *actually* `fac_1_put_ad`. Calculating the difference between `fac_pow_put_ctl_opl` and `fac_pow_put_ctl_rgl` will tell you how far off your wgdc table is from your actual wastegate control.
