In your xdf, certain maps have their axis as an individual map, for example Lamfa COL axis Lamfa Row axis and Lamfa map. Why is it labeled this way? Is it to make it easier to adjust the axis? Winols lets me put a different multiplier on each axis and output so i dont think its neccessary to layout that way unless using tunerpro. I have been transferring this xdf to winols to help me define my 018DQ ecu and i want my stuff laid out in a way that matches what everyone else is doing. Thanks

I assumed that was the case too since the only axes labelled separately are the ones that were modified. Just do it the proper winols way and you'll be fine.

In the three ols files that I have been using to locate maps for the 518AK, KFMDARO has four maps, *0_A, *1_A, *2_A, *3_A, with two shared axes (See attachment).

In the place that I thought that they should be the maps don't make sense (see attachment).

I have the same issue and I tried to search for these maps. I guessed the same locations as you showed, but maybe there is only one KFDMDARO map in this case (as in mine - ECU is 906018B). So maybe KFDMDARO_1_A that you show should be KFDMDAROS and KFDMDARO_0_A is just KFDMDARO.
Maps appear to be in the following order KFDMDADP, KFDMDARO, KFDMDAROS and KFDMDPO is a bit further. These are the only locations I found for KFDMDx maps that look similar to what I saw in fully defined ME7/7.5 files.

I didn't test these, so I'm not 100% sure. I could have missed something.

Ok so I think I have a disassemble code to work with... but I need to play around a bit to understand.  Any good tutorials to follow?

The tunerpro xdf was set up this way because it is easy to link axis data to the maps in tunerpro.  Feel free to set it up however you like for your own use.

If you want it to be EXACTLY like in this thread, use tunerpro!

So we need a disassembler. Who is up to the task? Rich says he's working on it with mixed success, is anyone willing to take this on or give Rich a bit of guidance? I know it's a "beginner" thread, but the current timing swings are not satisfactory to call this "good enough". This is me reaching out to the advanced guys on here to help keep this thread moving, so we can get it right and put it to bed.

 
I know I'm going to get shot, but please set the 2 main tm maps to 99 across the map to see if this sorts the timing swings, if it does then you know the answer is relate to the torque monitoring, then your choice is to either go the "right" route and fix the maps or live the fact that you might never get level 2 tm kicking in...

Given the fact that we don't have the appropriate RAM locations to log, I think this is a fine idea to help narrow things down.

So to try this out I'm to set ALL map values to 99, or just certain rows? here's a shot of the stock values:

What are the X axes of these tables? Y is obviously RPM....

Hi all,
tested this file on my A4 B6 with BFB (163hp) Engine. Runs well, but the car won't run faster than 220km/h (137mph) / 5th gear and i had some way left on my pedal and did not hit maxrpm...

Considering VMAXNB is 205kmh, that makes sense.........

I should hope you have a good road to drive on at that speed. Looking for more than 220km/hour on a public highway around here is a fast way to get yourself killed. Tire rating also becomes a factor. Please be careful.

Please check the XDF, VMAXNB has been there for a while.

Sounds fun. If you get the chance, please do some logs of the file (3rd gear pulls from 2500-6250rpm). We need some more data to work out the bugs on this tune. Some high speed cruise logs would be interesting too.....simply can't do them where I live.

Ok, i just set VMAXNB to..149.12 to reach (maybe) 240KM/h? Thats all?

What about NMAX? Should is set this higher too or will this affect other maps?

I'm try to make you some logs next weekend but only if we have still no snow here...

NMAX is engine speed limit (in rpm). This is stock on the community file at 6800rpm.
