Been working on an update for the 00000D07596401 folks.

XDF definition was absolute garbage. Several VANOS tables undefined (oh, and the "warm" tables don't influence anything but idle and engine overrun) AND garbage conversion. MHD logs one value, XDF calls them out another way.

So far...
Defined and fixed VANOS tables
Defined Valvetronic tables
Defined Injector Timing tables
breakpoints for all

Looking MUCH better and the top end is MUCH more open, now that I can actually adjust VANOS.

I'm interested, what does this mean for us N55 guys running MHD? Was VANOS not open before?

Yes but I'm catted and stock exhaust and assumed that was why it was not working at all for me. Even on aggressive.

Do you work for MHD or something? or selling the XDF's privately?

I reset all adaptations before the flash, and then also tried resetting the throttle adaptations after I noticed the sensation. Didn't seem to have an effect.

I have less than 100 miles since flashing, so maybe it will go away as it settles in?

I was gonna wait 'till I purchased the monitor module so I could take a look at the logs and post them if it came to it, but since you mentioned the same issue, I figured I'd chime in.
I also have this bucking at highway speed. Doesn't happen all the time, but when it does it's kinda scary cause I think it's misfiring. Every 3 - 4 seconds or so it just stutters a bit.

I've had this for months, so it definitely does not go away with time.

I had these little stutters every 3 - 4 seconds on the OTS 93 stage 2+ tune. It only happened when I was cruising between 65 and 70 mph. If I cruised at 75+ it would not happen. Currently working on a custom tune and the stuttering is gone. 100% tune related.

Uhhhh.... neither? I'm a software engineer with a background in controls/PLC/script and this has been right up my alley. If you're looking to get your hands on the XDF, I'm more than happy to provide, but I am absolutely in alpha stage. I have not done testing to see what table comes into effect when. I've just been scaling all my tables the same way and copying the same VANOS data everywhere. I see the size of the tables are larger in some places and smaller in others. I am sure that is spool vs cold vs warm, etc.

It looks like they may be organized in the BIN in an order that explains the numerous tables, but right now I have 23 VANOS tables all in all, along with 10 Valvetronic tables. Takes a bit more time to figure that out.

I mean, yeah, I log my vehicle for hours and hours each day.

This is a trim from a log at WOT. It's not terribly impressive because it's just from this morning, but you'll get to see where I have timing, vanos, and others at. I have not scaled load/torque, and WGDC is lower than where it will be (I'm increasing boost over a few revisions to dial in ignition).

What you won't see is the injection timing!

Also, scaling the XDF for VANOS and how it is shown in the MHD logs (delta degrees from TDC) as opposed to just scaled at 80% of what's in the bin has been REALLY helpful.

PS, who do you guys use for board IMG uploads? This one SUCKS

Probably VANOS and injection timing related. Everyone seems to forget the two are linked and I haven't seen a lot of definitions for injection timing.....

Dunno about your HW rev... What I do know is that my XDF for my HW rev was NOT influencing anything in light load, heavy load, or WOT. I believe it was literally just off-throttle and idle.
Plus, VANOS doesn't "open" and "close" but instead advances the intake cam or retards the exhaust cam. Please refer to this Image

You can double check your VANOS tables vs MHD logs by rescaling in your XDF like so.... I know the intake is correct, but I still have mixed feelings about the exhaust, but it's good enough for the girls I go out with.
INTAKE - ((X/1.25)-120)
EXHAUST - (115-(X/1.25))

Hi guys,

I just updated my 2013 135i DCT on Stg 2+ from 1.6 to 1.7 and am noticing something is up with the throttle. It has a mind of its own. Being a late e-series, I can't downgrade...

If I keep the throttle steady, the car accelerates and decelerates on its own.

Any ideas on how to fix this?

I have noticed EXACT symptoms. It's so bad that even my wife commented a few times.

I think valvetronic was def messed up on these last few maps revs.

You were having issues before right? Welcome to the club. I've been in contact with the developers and was told they will be looking into it. Hopefully it's not super low priority.

The only issue I was having before was with the DCT when coming to a stop, the rpm will jump up as it's downshifting into first and lunge the car forward, this still happens occasionally.

I don't think this new issue is related at all.

It could be VANOS, but in my efforts to define my own DME, I have noticed similar issues with unexpected behavior when I make changes to one table, but don't have another table defined (and therefore haven't made the same changes to it).

This causes a sort of bounce back and forth between two data points.

i.e. I defined all my valvetronic tables that I could find. I changed the tables radically, but noticed a WEIRD issue where an input of 2% accel position would result in 20% increased throttle position. This was due to my spool valvetronic table not being defined/changed.

I have plans to release a form of "OTS" bins and much more defined XDFs as time permits. Hopefully this discourages definitions from being withheld. In all honesty, even if people had their hands on the full blown definitions, I don't think it would cut into the revenue of any "e-tuner" since most of the bmw/bosch tables are exceptionally difficult to manage, compared to cars of yesterday.

Is it currently possible to change the rev limiter with the mhd files? If not, is this coming in the future?

To add to the unexpected behavior...

Changing VANOS of valvetronic results in odd behavior between
1. Commanded Load
2. Actual Load
3. Commanded boost
4. Actual boost
5. Commanded throttle position (valvetronic)
6. Actual throttle position (valvetronic)

I think there may be other tables underneath that help VE/target boost/etc.

no,

somehow some people have shown logs of the throttle in th elog going to 1600% which isnt even possible. Been trying to replicate it on my car, but never have seen it happen at all. SO trying to figure out where the issue is.

I'm going to do this I had the issue on my x1 n55. What kind of logs would you like to see for this. I'll try to flash back today and buy the monitor module to get some logs.

I was able to exhibit this issue with regular driving.

Here is it happening while decelerating without even being on the gas pedal. See the 3 green TPS spikes.
