From beemer FR

WDKUGDN 100% for disable the function.
Application: throttle blade angle at begin ps/pvdk >= 0.95. ps = intake manifold pressure
pvdk = pressure upstreams of throttle blade

Can only see it being useful for custom work in that area? you'll need a map sensor to calibate it

more:

This is org 551R file.
Something i am missing here?

Yes. The ability to look past simple map changes and into the ASM where this hack is executed.

You are trying too hard. I know you are a teddy bear Wink

. I have seen the line but i did not know what it represents
You must explain now when you have offended me.

With what wdkugdn does in there, I would say changing the psi that it is dealing with is custom work.

I would agree that messing with it might not be necessary for most and would only be a minor change anyway.
But, the further your cracking psi deviates above the calibration, the more important it may become.

If I get bored I may have to try the 100% thing just to see what it does.
My guess is as long as wdkugdn is larger than the actual point of restriction, the only thing it might affect is wear and tear on the tbody.

that's my thoughts too as mentioned. The most important part imo is the axis recalculated. I went from 0.4 bar to 1bar actuator and it was sweet as mentioned 5120 PID dialled in and it limped 69 miles home with the IC to the pipe off lol steady 60 mph.

Bigger/custom intake manifolds perhaps? I'll trace the code tomorrow to see if it sheds any more light.

0x8E75E

I would like to use that workaround on the 5120 551R file. Is it possible to transfer to another bin? Just 0x8E75E-0x8E76D....? Theres more than the stuff at 0x8E75E modified in comparison to a stock file so i was a little gun shy of trying it.

Yes if you disassemble both and the code is the same

The way I look at is:

If 30% plate is the lowest point where 6psi of airmass can flow without restriction at 3000rpm,

then turning the boost up to 12psi at 3000rpm will cause the plate to become a restriction due to the increased airmass flowing.

This increased airmass would require the blade to be opened slightly to not be a restriction.

I dont know though, maybe the larger airmass is packed down to the same volume as it was before and doesnt have a problem getting through the same plate angle.

*numbers are not accurate and just throw in as placeholders*

I looked into this recently and the code equates for that
