How to tune the throttle in 2.3 ecoboost ?

[ammar.alqisi]

Want the throttle open smoothly not open then close then open then close .

I see many logs here, and the throttle tuned, how we can do it ?


I tuned everything except the throttle

The ecoboost uses the throttle to control boost spikes and overall stabilize boost pressure. Its normal for it to fluctuate. As long as you are not hitting other limiters, and your torque sources are staying with driver demand, your fine.

Whats happen if the throttle keeps open ? What will happen with the boost?

[Trent_Petersen]

The throttle can respond quicker than the wastegate for managing boost levels, so its just removing one more layer of safety from the engine, with no meaningful increase in performance. You haven't posted any tunes or logs, so again, I'm assuming all other limiters have already been raised and we are just talking about the normal, small fluctuations in the throttle to fine tune boost levels.

In order to get the throttle to stay open you must ask for a load that it can never reach.

What happens if the throttle stays open is that boost will spike over the target and then come back to its intended lvl, ford system works like that to give you a better throttle response with the turbo
