EDC16 VNT Settings, Why does Output Still on %75 Duty?

**Emre2blue** · 27th April, 2019, 09:16 AM

Good Morning,

I'm adjusting the VNT for my Car, EDC16C39, As you know VNT Settings are Starts with %75 Duty cycle at IDLE, I need them to start %85 or maybe %90 for the boost, I made the map, but when I datalog the car, It stays at %75. Why ?

I've also Set the "Inıtial Value for Control Signal" in PCR_CtlVAL_Calc, Am I missing something? I know that the map is not the "Regenerative" one. So Please help?

I think that VNT at 75% is the maximum possible closure but I'm not sure ... even if you set 85% he can't close them up ...
did you modify all the VNT maps of your file ?? why you have to close more ??? we should try to "play" with the PID maps to regulate the pressure where you need it

I have an Electrical Actuator Instead of N75 Valve, So that's why %75 setting is letting all the boost go away, I need to set it higher to keep the boost. You can check my youtube channel, I've connected original Electrical Actuator to replacement of N75 valve.
