2020 Raptor Throttle Cutting-Turbo FMEM

[Lightning95TT]

I am attempting to tune my first ecoboost and I feel like I'm missing something here. 2020 Raptor 3.5 ecoboost full race turbos with intercooler and s&b intake. I am just starting the process and as I'm raising limits and adjusting I'm getting throttle closing. I'm not familiar with the ecoboost but have tuned lots of my own 15+ speed density f150s I was hoping it would be about the same. Can anyone shed some light on what I'm missing here with the throttle closing or what I should start to look at. Thanks in advance.

The modern ecoboost controls to a target MAP primarily with the wastegate and then fine tunes with the throttle at WOP. Ford never intended for the throttle to go wide open and stay there. You can increase load, torque, and map limits and targets and the boost will increase but the throttle still modulates, which is how it was intended to work. You can lie to the throttle body model to get it to go WOT, but then it’s not controlling the way it was designed.

Dont need to screw the TB for this to work, TB modulation
is also not the way it was designed - when TB is closing something is not right. Sometimes it will close TB without any
flag and that is a problem to solve but... nothing i was not able to
fix and i never had to trick anything

@lightning95tt, this is a pretty good article explaining the rationale and logic: https://motorsport-developments.co.u...t_Control.html

Away from my tuning laptop so can't look at your log yet, but I will.

But, with the full race turbos, you are probably going to have to spend some time fine tuning your wastegate tables. They don't need to move as much to flow the same air as the stock turbos. You don't want throttle stuck at 82 at WOT with those full race snails on there unless you want 90 lb./min airflow and some broken stuff lol.
