Hello,
I am quite new here in the forum and already read some about software things... I am studying automotive engineering in geramany and I'm very interested in learning how to do my own software. I am 21 years old and quite new in the buisiness, so I dont have already the skills to do my own software - but I have a car which needs a software - so actually I got somebody who's doing my software for my 2002 A6 Allroad 2,7T ME7.1 .. This guy does is for low amount of money but I think he maybe isnt doing a very good job, also not the best source to learn it. I dont know the guy personally because he lives quite away - so I send him the logs and information he needs and he sends the updates to me - and he also needs often very much time to answer. So I'm right here and hope that somebody of you can help me because my software guy cant solve my problem. I have throttle cuts , especially in high gears.
hardware:
RS4 air mass meter
2.8 camshaft
RS4 turbochargers
 and pretty sure everything needed for the power... 550 jets, rs4 clutch, downpipes, big hoses, ....

for some weeks my software guy said that he thinks the cuts are caused by wrong air value - by a leak or sth else. Im quite sure that my system is 99% close (little leak in charged air coolers). I just logged some things like throttle valve and boost pressure and saw that my boost was like 200mbars above the specified - so I was sure its coming in to the treshhold and reduce it by the cuts. I remembered that the wastegates had a little bit much pretension when I revised the chargers - so I readjusted them and my pressure came defintely nearer to my specified. (now like +- 50-100mbars) But my throttle cuts didnt get any better.

to complete: I DON'T feel the cuts in low gears (its definitely in relation to the resistance for the acceleration - more cuts uphill). In 3rd gear f.ex. I feel it uphill with middle throttle (not at full throttle). in 4(often), 5, 6 I feel it at full and middle throttle - not at low throttle. I also hear the the charge air valves open every time at cuts. The cuts also begin to come as soon as the turbocharger begins to spool (like 2500rpm) - no cuts at all on lower revs.

I think this moment its everything I can tell about it. I know that you would need some more information to help me with it. Just tell me the logs or what else you need to analyse my problem - if you want to talk - just tell me what you think about it - I am defininetly interested in learning, I just dont have always enough time.
The software does this moment about 330g/s air mass flow and I am going to 480hp - just want to fix this problem first.

I attached my actual software. I didnt make out everything already but I hope you also can maybe tell me something about the quality of it I just didnt understand some things like the delta pressure threshhold (seems like it is made about  1250mbars instead 200 (I remeber) ?)  I really would appreciate to be able to make my own software - and I think I would be able to do it if I had just some more knowhow (maybe you help me). So I already flash the software by myself - looked to everything in winols and tunerpro (some things I didnt make out but Im going to) and tried the checksum checker - the checksum corrector didnt work for me already (going to search the bug)

Thank you guys for reading my post - I hope my english is understandeable and you can help me - hopefully for some more good communication on nefmoto

Hey... Im going to do some more logs as soon as possible. The difficulty is that the cuts are quite fast and not shown very well with the logs. I attached some videos, for now, where you can see the cuts and also the behaviour at low gears and high gears high rpm. I try to send some useful logs in some hours.

Hello..
Thank you guys for your attention.
Im just little fucked up right now - before some hours I wanted to take my car for driving home and doing the logs.. I came to my car and see the front of it laying down and recognized that the bellows of my air chassis just burst by just staying there. So my car is not at home right now and I need to repair it next weekend.
So I need to wait for the logs until next week.
Can you tell me whats better than VCDS? this moment I only got the tools to use this.

edit: So, Im going to bring up this thread next again. And dont care about my last post - I will send the videos with the logs, just forgot to attach them

Sorry my quick answer, just little bit stressed right now.. I already reviewed S4wiki and found the stuff

Don't use ME7L GUI, use visualME7L, as recommeded here, where you were told to read.
https://s4wiki.com/wiki/Tuning#Logging_utilities

You can follow the rest of the guide, just use VisualME7L instead of ME7LGUI

A friend helped me with it, but I just become "Error! Exite Code:4 => Could not connect to Ecu, exiting" with the visualme7logger ... I mean its the same code, just another gui right?

Disconnect the cluster fuse.
