Your car is definitely NOT running fine, from the looks of your logs. I would not drive it.
Ok I will listen to you, and start study how to scale everything to be as it schould.

if its worked then why you start the topic?
its a primary load inputs and in your case theyre should be calibated fine

170gs its a typical k03 limit
youre basically running some kind of st1
I mean it work fine for every day driving for me that is enought. I am still in learning process how ME7 works, and tuning on it is yust a bonus.
My turbo is K03 with K04 compresor wheel, so it can go to about 185-190gs

Start with calibrting em, its not hard and all covered here
Its a hard (and meaningless) way to find a problem if so many things fucked up

After calibrating I will have other work to done, I am sure at 190 gs BTS will kick in, and so other MAPs need to be modified, as I said in future when I have time I will do everything accordenly. For now, this "shortcut" will work, trust me this engine will withstand it. He had gone tru worse than this.
And at the end if I reach dead end, I always can buy stock MAP and MAF

As the prj said, here is mehanical problem. Hoses on N75 was switched, I put it back as schould be and now I get boost i desired

Thank you all for your help

Stock k03 will not go over 1 bar boost (even at peak) on AEB with front mount intercooler. At least not from my experience

Then you never tuned AEB or AGU that was functioning correctly.
I have done more than 20 of them, and if they don't have boost leaks or other problems they all hit 1.1-1.2 bar with 75% DC in my experience.
FMIC or no FMIC. That FMIC is not gonna lower your temp by 70 degrees. Mid pull the IAT will be max 5 degrees different, only on a longer pull will there be significant difference.

Look at the log of the screenshot that I sent you - the date is from 2012. It's 2019 now, so I have done a few Wink

Underscaled boost sensor is really dumb though, just scale it - there are 2 constants to change only!

I don't know then where is missundestend, I and including my friends, and all tuners I know confirmed me, that it not able to get more than 195 HP from K03-029.  And all go to around 9-10 psi to readline. I trust you, i bellive you are better tuner than me, I am still in learning process. This is my daily car, I don't have too much time to optimize map to perfection. But as I say I was not ablle to get more than 9-10 psi at high rpm, even when the WG is not noneccted at all.  Maybe my WG spring doesnt work best,or is not enought tension on it... For me it doesne't mather beacuse the garret is wainting in garage


I wil give it a try

This was my car with AEB harness and K03 hybrid

Also you converted to DBW right, and the used wideband from diesel too ?

I was talking about mid-range boost - there is no problem. On 7000 rpm 0.7 bar sounds correct.

DSLOFS and DSLGRAD is for MAP sensor. Shouldnt be hard to find them. Formula on how to calculate proper values is in FR.

I know, but it is easier to change MAP. On my car is easy to get it out

I am curious lol.. you have a DBC ecu by default setup - the AWT is 1024kb dbw , wideband? ecu so I am assuming you converted the pedal assembly etc.

Yes yes, ECU is 1024 kb DBW, wideband. And yes the pedal (on car) is converted to electric.

Ok, i put the original MAP on car (the MAF is still from 2.5 TDI). LDRXN is set to 1-1.2 bar. But boost desired is only about 0.8 bar.

LDRXN is not in units of pressure.

The conversion that is found on s4 wiki can be off by more than 30%.
