I need some help to change the wastegate strategys in S8 ecu with the latest firmware. I need to use MAP closed loop, and Turbo Speed closed loop strategys in a car with restrictor, but how can i change between the strategys? I cant find closed loop enable settings in the software, only the control tables are there. How does the ecu choose the actual closed loop strategy?

Pretty sure closed loop is always active, only determined by the threshold settings in Wastegate Control, Standard Strategy, Enable.

And for shaft speed, these are further adjustments or corrections applied thereafter ? rather than actual speed targets ?

Recent video ? Although it maybe looks like firmware options for the 8 are different from the 6Plus here.

Thanks, I know that video, and I'm using S6 Boost control, but S8 Boost control seems a little bit different, I don't know how its changes the strategies. I need to control a restrictor. So, the base idea is using MAP closed loop with a little bit overshoot until the restrictor choke point, and than change to Turbospeed control near the choke point and controlling the turbospeed there to keep the restrictor a little bit before choking.

done...

Thanks a lot! You helped me a lot!
