What .XDF file is everyone using for N55 98G0B ECUs in TunerPro? I'm using https://github.com/dmacpro91/BMW-XDFs but I'm not seeing WGDC (BASE).

Ah, I'm operating on what I know from my N55 Cobb AP and how I tuned that.

Is there or will there be an MHD N55 tuning forum of some kind? Or when will you be able to publish a tuning guide?

Unfortunately, Cobb had many things incorrect on mapping these cars. but all is fixed and getting more advanced by the day.

Tuning guide, no ETA, honestly never thought about an actual tuning guide persay.

The Cobb AP tuning guide was meager at best but it was something.

Honestly though that's partly where Cobb failed and utterly abandoned their customers. They refused to organize or even endorse a tuning forum of any kind for customers to self-help each other, they refused to answer any tuning questions from customers, and they purposefully crippled the product so paying customers had to pay even more to get help for maps (from tuners) that they the customer were ultimately unable to even see.



So far you've righted a number of those wrongs and for that the community is very grateful (or at least I am ). Anything further you can do to help us is just that much better.

yes, current OTS maps are still in BETA so we can collect more data from a larger audience.

Those logs look good. no timing corrections to MINIMAL. which is great. What transmission do you have? Some overboosting at spool, but not major. And is one of the things im looking to fix with the next OTS update now that i have more data from the users.

Sounds good! I gotta learn to read data logs lol. This is a DCT. Looking forward to more power gains with next update

Looks like I get similar overshoots with Stage 2+ (v.20) and subsequent throttle closures/ignition retard.

I was hoping to log the differences between v0.20 and v0.21, but my car is in the body shop for the next couple weeks. I'll post the logs I've got for now...

CAR:
2011 - 85k miles
N20 plugs (1step colder) @ .022"
Aluminum Charge-pipe
5" intercooler
3.5" Downpipe
DV+ diverter valve

LOGS:

Here are 2 logs of my car with a COBB Pro-tune done by COBB (more aggressive than stage 2+ but also lacking severely in a few places):
http://datazap.me/u/banks334/2-pulls...og=0&data=4-16

You can cycle through the 2 logs using the "change log" button at the top left...

Here is a log of a 3rd through 4th gear pull PPK only:
http://datazap.me/u/banks334/ppk-fla...og=0&data=5-16
Here is a log of a 4th gear pull PPK only
http://www.datazap.me/u/banks334/ppk...=0&data=2-5-16

Here are 3 Logs of Stage 2+ v0.20 3rd gear through 4th gear done back to back (car was still learning new flash - timing almost clean by 3rd pull):
http://datazap.me/u/banks334/3-pulls...og=0&data=5-16
Here is 1 log of a Stage 2+ v0.20 4th gear pull:
http://www.datazap.me/u/banks334/mhd...&data=2-5-6-16

Virtual Dynos:

PPK (red line is a 4th gear pull and blue line is a 3rd gear pull):


COBB ProTune (Various 3rd gear pulls):


MHD Stage 2+ (3 3rd gear pulls and 1 4th gear pull):


Not sure why MHD appears much stronger than COBB when plotted on a Virtual dyno. The COBB protune definitely pulled harder and dyno'd higher than what VD is showing... It is also faster time wise through 3rd/4th gear than the MHD tune.

Comments:

Throttle:
Stage 2/Stage2+ maps would benefit from a more linear throttle. The slightest touch of the pedal causes an overwhelming load request for the 255 rs3's I have in the rear. Car breaks traction entirely too early/easily when just trying to cruise around town or roll into the throttle. The PPK throttle map felt much better, not sure if these OTS tunes are overwriting the base throttle mapping (PPK in my case) with the stock throttle mapping, but I am disappointed if it is...

Boost:
There appears to be a few places where some WGDC needs to be smoothed out (early in the rev band) to prevent over-shooting target boost. Also, target load ends up being exceeded between 4200 and 4500 RPMs causing a throttle closure and timing retard.

Spool:
Spool can improved. Turbo appears to take slightly longer to spool running Stage 2+ vs the COBB Protune.

Took a few logs on stage 1, 91 oct. Boost levels seem good but getting a ton of timing corrections. Also car now seems to be hesitating with the boost. Sometimes it feels strong, other times it seems like it's being limited.

Log uploaded to datazap. Will do a more dedicated logging session across a wider RPM band when I get a chance.

were all of the logs done on the same road? I was told VD results can vary greatly if not on the same road. Meaning one I slanted uphill vs downhill.

update MHD app. then load the latest Stage 1 map. many adjustments have been map and implemented into the current v0.20 Stage 1 maps. Lots of those issues were rectified in the update. flash that then try re-logging. Thanks.

Yes, I log on the same road doing the same traffic pattern every time. I need to be more consistant with starting rpm though as that seems to cause a massive shift in the torque curve when starting runs below 2700 rpms.

Ok, thanks for the reply. I just updated the app and will do a new set of logs.

In regard to an earlier post, I'm not sure why people make fanboy comments when good information is released. To them, everything is a competition. Unfortunately it's a waste of time and usually counter productive.

Just to set things straight, this is not a competition. Justin and I have no animosities toward each other. We actually collaborate as we both have a common goal, provide the best tunes possible in support of MHD Tuning.

Below is a side by side comparison as to where we are with tuning our shop PS2 car. 2012 135i MSport DCT on E30 with Stage 2 LPFP from Fuel-IT. As you can see we are both doing well in our efforts to get the PURE Stage 2 turbo tune with MHD.

Bottom line, regardless of who does your tuning, you can't go wrong with MHD stand alone. I can't thank Justin and Martial enough for everything they have done to get this platform to where it is today.

That's awesome! Where is your shop located? Are you tuning your shop ps2 dct car on your in-house dyno?

Would love to hear about what you guys are collaborating on. As other users have questioned, it was claimed there were no issues tuning a DCT car with PS2 turbo using MHD (And there shouldn't be). Now there seems to be some contradictory statements being made in your tuning thread. Just curious as to what the issue is that no ones cracked the 200 load ceiling or gotten the PS2 to hold power 'till redline. I wish the people dropping money on a custom tune the best of luck because it looks like we are months of revisions away from a working flash tune (which is being advertised as working and available now).

He's cracked the 200 load ceiling on stock turbo already.

My comment was in reference to a PS2 setup though? Anyway, I don't expect a proper response back. It was more of a rhetorical post.

I look forward to getting some comparison logs as the stock maps progress! Good luck to the upgraded turbo owners with whoever they choose to do their tuning...

I do all of my N54/N55 dyno tuning out of Portland Speed Industry (PSI) because they are local to me. Most of my tuning is done in Mexico as my focus is driveability.

I won't go into great detail regarding our collaboration as that has no bearing here.

Comments regarding DCT tuning is past history as we had issues tuning with COBB which included post shift bog and clutch slip. I'm not seeing the same issues with MHD that we had with COBB. It also helps that I have my own DCT car to tune on now. You can't really see shift bog within the logs. Something I should point out is the fact that we didn't see the same issues with MT and AT cars.

Not sure what you're referring to by making the statement that no one has cracked a 200 load ceiling. I have personally ran a 214.6 peak load with my stock turbo and was able to demand a boost target well above 22 psi.

The PS2 poses a few challenges with fueling, which is no secret. I have port injection going on my car in the next two weeks. That will eliminate the fueling issues and allow for the increase of boost. I'll post up a new thread once I have something to share.

Thanks for the great questions which I appreciated. Hopefully I answered most everything. We are all here for the same reason.
