Thanks! I live for encouragement :)

Some testing today, I added a progress bar to writes of multiple tables.

Some timings writing 4 completely new 17 * 18 fuel maps (16 bit) with various cables:
MVCI clone: 13 seconds
Kvaser Leaf Light HS v2: 1.4 seconds
Tactrix Open Port 2.0: 0.8 seconds

Guess which device I will be recommending?

Bench testing going well - flex fuel sensor input is going through many stages to end up with a correctly blended fuel map value which varies as the fuel maps are edited in realtime and the flex fuel sensor input is moved. Need to add the rest of the new tables to the xdf and test them, they are already in the ECU.

Good progress with xdf, but it is tedious as the csv import to xdf doesn't work properly and it is great fun bending your head around how the axes get flipped by BMW and TunerPro. Need to break out the axes into separate tables to be able to edit them in TunerPro because you dudes will not be happy with 180 load. You want 327.67 load and 1023Nm to clip the max available.

The N54/N55 tuning guide by V8Bait states MHD and Cobb have a max load of 240.

The guide I referenced is N54 centric so it could very well be that the MEVD17 has a higher limit.

No I don't want the Windows feature update. But it does not make you a communist if you use lambda for your flex fuel ECU's fuel map ;)

Additionally, it is "petrol" not gasoline. Hence _P for the petrol/gas maps. I will name them something more friendly later.

Completed all the new tables in xdf. Axis link is nice to use and solves one of the main problems with TunerPro, but nedds extra work for the xdf creator.

Is Tuner pro the only option for live tuning? On MS43 the xdf was ported over to romraider which I found much easier to use but I don't think has live tuning support.

Yes. For tuners of other platforms I might do something in WinOLS. Not aware of other options apart from 5 figure pro software that needs a2l files. Asap2demo also needs a2l and comms performance was poor.
