Okay, I found a lot of related maps. Using English to germen translated keywords like "charge pressure = Ladedruck" and a searching the damos. It will take a bit but I will update the maps I find and keep this thread updated.

Load related to speed, max map voltage and so on.

I suspected speed over time and pedal position would be the best way to determine load and a substitute for vehicle speed could be air flow increase over time.

Anyway, finding/crossing these maps takes a bit but I'm on it....

I understand the material you've quoted from the TTweakers' Guide, thanks. I was trying to be diplomatic while pointing out your approach. I'm concerned from what you're reporting that you're trying to tune without fully appreciating the structure of ME7.x.

Changing the injectors and/or FPR without recalibrating KRKTE is generally regarded as a fundamental issue and there has been plenty of discussion on Nefmoto about the topic recently. You incorrectly reported that bhp = MAF x 0.8 in your screen dump of your VCDS log when you do know which way round it's supposed to be.

You've looked at a 225 PS definition file I've posted and commented, so it's fairly clear we all know where all the maps and constants are to within a few lines of hex code already. Surely you have enough info to tune your TT successfully if you've been tuning for 20 years.

I'm not trying to trash your efforts, just cautioning that you need to take care. Pro tuners I've talked to have been asked to correct a lot of dodgy 'pro' tunes, never mind amateur attempts.

Change Injectors? My injectors are OEM...

The 7.5 is not the same as the 7.1 and after following the s4wiki guide only to find my ME7.5 does not have KFDLULS, I began to try various setups to figure it out on my own.  Apparently I have a regulated BOV that just brings the boost down evenly when calculated load goes down. I am not convinced the way the 7.1 calculates load is the same as the 7.5 but that is what I am working on.

Also 2550mbar is not just five horsepower. Stop it with fueling and attacking me. I will get to fueling after I figure out boost. My car will be fine until I do. My car can trim to 25% either way so I am fine for now.

 I really don’t care what opinions you may have regarding what I know or don’t know and for what it is worth, I have given more to this site regarding the 7.5 than I have found.

TTQS yes I used your damos file and it is not for my car so I had to find every map and if you are suggesting that what I have done was easy you are wrong. The experts you speak of did not go to class to learn how to hack an Automotive CPU and I’m sure they spent plenty of time testing to get to the level you consider to be an expert. I don’t mind doing the testing also and again I am not an expert but I have actually achieved results with my work. I am also providing my hard work for anyone to show my thanks to everyone who did the same with making information available for me. This work is the beginning of something and you can choose to be or not be a part of it but stop attacking me and sending my posts off topic. I’m sure there are a lot of people who want to learn and develop more performance with the 7.5 and it is funny that you have actually never tuned and I bet even built a high performance engine but you are the first to tell me that what I am doing is wrong.  It would be more productive if you would help me find the maps or talk about anything related to how the 7.5 calculates what it considers to be load.

Thanks nyet.

I take it the MAF and RPM curves are used with more than just load calculation so the constant must be the key. I found a "translated" discharge curve that had 501 points KLAF. I suspect it to be related to the BOV.

I suppose the calculation is the best way to do this without disrupting other functionality of the system.

Is this a single constant or group of constants as a member of a function generator?

I will plot it out as a single constant on my graphing calculator to compare to vag com. The problem with logging with vag com is it has a millisecond delay between writes. You can see it when you lift throttle. I may have to video a test live to get higher fps and more accuracy. I have a virtual machine that will record my desktop session but I am not sure if it is fast enough.

Thanks again...

I agree. IMO you are barking up the wrong tree and not logging the appropriate data.

I suspect you are getting throttle cut.

Log throttle plate angle, boost, and wgdc.

Does setzi's logger work with 7.5?

"he 7.5 is not the same as the 7.1 and after following the s4wiki guide only to find my ME7.5 does not have KFDLULS, I began to try various setups to figure it out on my own."

Some do some dont, find KLDLUL
