Well if someone wants you could track down in FR to see what it does exactly because either its an auto thing or idk. Since the vacuum booster only works when you are in vacuum( which is okay since you are never braking with gas on) I dont see what it has to do with pressure values, and you cannot left foot brake with me7 in stock form anyway.

The electric brake vacuum pumps on the automatics could be activated via output diagnostic test mode in the ecm. That said I don't think any of the jetta's, golfs, gti's or beetles had any kind of a pressure (vacuum) sensor in the booster line that was monitored by the ecm. The Passat's and touaregs did though. So my assumption is the sensor would have been common on the audi's, but my audi specific knowledge is limited as I don't work on many of them in a vw shop.

Electrical brake booster in Audi exist only with automatic gearboxes and after october 2000 , there is a pressure sensor on the vacuum line between the firewall and brake servo.

More info is in ssp https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.volkspage.net/technik/ssp/ssp/SSP_257.pdf&ved=2ahUKEwi12YOQsKbqAhXrkYsKHU7AADAQFjAAegQIARAB&usg=AOvVaw2bzYoTDcU-IgRfpgMVqp1n

Finally got a log with ps_w. I don't know how dead on it should be if the MAF were scaled perfectly, but it looks pretty close through the log to me. Or is that not close enough and I should touch up the different areas of MLFHFM.

You're good, its fine.

A bit of underscaling never hurt anyone as long as your fueling is good.

Excellent, thank you. Just wanted to make sure I was interpreting what I was seeing correctly.

Hi,

did not want to start new topic, but I would like to hear your opinion about my log...
I have not had much time to play around with that 5120 hack, but since I got the sensor
back on and I want to get it working as it should.

1.8t, gt2871r, 730cc, 3,25" maf

I want to try 1.7bar of boost, but something is limiting/cuting it.

Actual boost vs requested are not maching up...
Is my problem caused because of KFMIRL/KFMIOP/LDRNX not set up right (asking not enough load)?
or is it something else... can someone point me to the right direction please.

There are 2nd and 3rd gear pull in the log. 2nd looks fine, but 3rd spikes badly...

So you think that kfldimx is way off? I have scaled the axis and I know I should change the values in it... as I did today... But I'm not sure is it the main problem

Also this was 2th gear pull... 3th gear goes way over the requested load

I have noticed on my car: 2nd gear pull 22 psi, 3rd gear pull 26 psi, 4th gear pull 28 psi. I’m assuming this is due to the load change and using LDRXN for boost request with KFLDHBN up and out of the way. Between busy life and work I haven’t had time to investigate any further. At some point I am going to change my strategy and get LDRXN out of the way and use KFLDHBN to control boost as I suspect this will correct my boost pressure changing based on gear/load problem

3 bar map sensor?
With your old version file i received "The 17705 Pressure drop between turbo and Throttle Valve (check D.V.)" with a 4 bar sensor in VCDS.
Something is wrong in file?

I have put several thousand dtc free miles on my car with the bin as posted. There is nothing wrong with the file for MY car. The idea behind posting the file publicly was to make the ASM stuff accessible for the 1.8T vw guys and to document the changes necessary to run E85 in my car, with my turbo, my injectors and my fuel pump. It is posted as a tool to learn from and adapt to your car. NOT to copy paste and blindly flash. Every change made to that file was made with knowledge and/or opinions from the tuning wiki and this forum. I had never even done a stage 1 tune prior to embarking on this project. I will tell you I am running a factory bosch map sensor. If you use the search function on here you will be able to determine what pressure rating it is. I spoon fed a lot Tao, even after you insisted to communicate via email instead of through this thread as I requested you do.

Hi.
I not get it for copy paste my friend , but the error has nothing to do with your modification for e85 or injectors or...stage 1.
I don't know how make asm changes and i get your file for them. all other modification not interesting to me.
I think your map calibration grad and ofs are wrong in the last file if you use 2.5 or 3bar map sensor, but this is not important for me.
And like i told you for old file , if all asm stuff was made ok , in VCDS the actual pressure must looks ok, but is not.
Thanks for your time and support.
