Attached is the capture log file and the output from ECUxPlot (using latest version 0.9r3.0). Obviously the Calc HP/TQ numbers are way off. I loaded the right profile for my car (B5S4) in ECUxPlot, did not change any constants or fueling values.
The boost graph looks reasonable, even the Calc boost numbers for actual PR and desired PR
1. How are the Calculations done for all the other stuff? HP/TQ numbers are way off, why?
2. Am I loggin the right variables?
3. What is the filter data option? if I click it the graph goes away
4. I see everybody talking about FATS. What the hell is it? The show FATS window under option just shows me an empty window.
Thanks for the help, searching the forums didn't help me much.

FATS - For Advancement of The S4 - Is a number based on third gear acceleration.
nyet can probably answer your questions better than I.

The filter option searches for a WOT run of a certain length in 3rd gear. If you don't meet that criterion, you won't see any data if you enable the filter. You can adjust the filter parameters in the filter menu.
If you aren't in 3rd (or aren't logging "gear") or aren't WOT (or logging accelerator pedal position), the filter doesn't work that well.
If your run doesn't start low enough, or isn't long enough, the filter won't let any data through.
FATS is ET from 4200-6500 in 3rd.

Well that explains it. The data sample I was trying to plot was a 2nd gear pull. I'll go log 3rd gear pulls and see what the graph looks like. I am loggin both gear and accelerator pedal position as well as a bunch of other crap.

btw, you can use 2nd gear data if you adjust rpm_per_mph and change the filter to 2nd instead of 3rd..
however, hp/tq isn't as accurate for very short runs due to inertial effects.

I have a very strange problem with ECUxPlot, could be because I'm missing something really simple. It just won't plot anything. The axis show up as I choose them in the drop down menus, but nothing is plotted on screen. It's the same on two different computers And the CSV file is straight from ME7 Logger. Any ideas?

nyet, maybe the program needs some pop up when you start it for the first time telling people they need to do pulls in 3rd gear for this to work... It seems to be #1 reason why people tell you that your software plots wrong even though it is right since they do pulls in 1st or reverse |

for SURE i totally agree.
i was working on a little "helper" dialog that explains why the filter didn't see anything, including advice on how to set the filter, but never finished it.

Can you add "Save Preset" option which would save current graph settings? This is really the only thing I find missing from it currently.

Also, Julex, if there are specific things you want it to be able to detect as "known" columns but they are named differently from ECUx or ME7L (e.g. from VCDS logs) let me know.

So far so good, it's been a big help already.
Some suggestions/requests:
* add ability to scroll (with mouse and left/right/up/down) zoomed in graph.
* shortcut to zoom in/out, ctrl + '+', ctrl + '-' and mouse scroll wheel would be awesome.
* ability to add actual values on top of the curves/points. This one is tricky as you don't want them all as they wouldn't be readable. Maybe have a choice of every n-th somewhere
* make graph remember settings for colors, fonts etc. Maybe make it a part of preset but I think it should be a separate item. Just having one that automatically saved and restores without any explicit menu for it is fine.
