Hi I am working on setting up an electronic wastegate valve used in VW 2.0 Turbo engines in my engine build, I have succesfully being able to control its position and played with dyno runs on different positions and with a closed loop with respect to manifold presure I have been able to get it to behave somehow similar to how I want it to behave to control boost all this by using the custom DC motro strategy and a rotary switch, On this example it did what I wanted it to do and opened the valve once 75KPA of boost have been reached, I know his way of controling it is sub optimal and I want to control it with the boost control strategy but eveytime I try on that one it just very erratically goes from 12% waste gate position to 100% waste gate position, I have no idea of what causes the erratic behaviour I am pretty sure it is something in the setup I am misunderstanding so I wanted to see if somebody could point me in the right direction, this is a screenshot for the log in which I was able to get it to behave like I want it using custom DC strategy and a log file for the one with erratic wastegate behavior ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/9/9840a8216e7a970b7d96772cc05fdb44626730f3.png) [20251102\_1827\_15.emuprolog](https://community.ecumaster.com/uploads/short-url/1pZpbQrhFkUrrIvwlp8Lk6mWzh8.emuprolog) (5.8 MB) ---

Screenshot for my Boost strategy settings, I am assuming this first table is supposed to be a wastegate target position based on what I understood from the help section, but the wastegate just does not follow it when I use the boost control startegy, also not sure I understand what is required on the duty cycle table, Any explanation on how this should be correctly done would be really appreciated, Thanks ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/b/bf345ece383ddac1753c24e778207d1779537aec.png) ---

You are commanding more boost than you are allowing on the DC control. 100% tps shows 200kpa, max for control shows 180 kpa. If you are hitting this, boost DC would be turning off. Can you post the cal file and a log? ---

The log is attached in the first message all the way at the bottom, which one is the calibration file? ---

Your boost control shows a state of -7 Below pressure min - 100% control. You also show no boost being built ever. TPS is about 35% max. ---

Why would the waste gate valve try to open to 100% if there is no boost? Not sure which setting I have wrong for it to do that ---

When you run electronic and use it as a custom motor your feedforwards for the motor and the boost control must work in the same direction. Meaning 100% would be full boost wanted and 0% would be no boost wanted. It sounds like you may have one of the controls inverted. ---

Ok yeah that makes sense, I think the wastegate position sensor wants to be inverted, I will recalibrate and try, getting more and more familiar with the log files, now that I am looking at the Boost state everything makes more sense, I noticed there are some states where there are always two options, it is either 0% control or 0% DC, how do you configure it to always react to the 0% DC instead of the 0% control? Thanks for your answers btw ![image](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/7/7f8d09692aea9f03b89f9646c824bbd0cb02b02f.png)
