Greetings from Bulgaria.
I've been reading this forum for a while and came up with a tuning file for my car. What I basically used is the file V7 and .xdf V7 from the well known tread.
I also used BitCompare or Beyond Compare to create my own .xdf file. What i couldn't find is LAMFA_ROWAXIS and LAMFA_COLAXIS and I'll appreciate if someone give me the addresses.
I also don't understand where is the difference depending on what Octane fuel the car is running. We Run 95 octane or 98 or 100.
Checksum are OK.
My question is is this file ready for writing in my ECU or I should make changes.
Thanks.

Include logs if you want your tune to be rated.

Car won't make boost with this file. What's wrong. Help please.  ??? ??? ???

you have A LOT more to read about and to test and try for yourself. Your file doesn't look horrible but you've missed quite a few things. Also, not having a clue what the difference between 95 98 and 100 is and making your timing map perfectly dead-smooth in 3D won't help much. Good luck to you.

Need map address please - KFMLDMX. Then I will make logs. 10x

I uploaded this .bin to my car created with ME7Wizzard.xls wanting 1.2bar of boost. Here are the logs. I have a problem with Idle - RPM not stable. Also 3rd gear pull not accelerating fluently, it's not like pull then stop then pull but i feel it. I now that something is limiting my requested boost and load. KFMLDMX still wanted. 10x. Any opinion will be helpfull.

There are alot of things wrong here, but one thing that stands out is that the MAF signal seems very low.  Have you scaled your MAF?

Certainly no need for KFMLDMX changes at these maf readings.    Do you mean KFLDIMX?

Didn't scale MAF. I haven't changed anything MAF, MAF housing or so. Why do I have to scale it. I'm following these instructions that I found here for 518AA or basicaly for Stage1.
LDRXN Limit to 160 or so and you won't really need to mess with KFLDIMX or KFLDRL
KFZW1 Reduce timing at peak load
LAMFA Add some fuel from 3000rpm on. Request an AFR of around 12:1
KFMLDMX Increase a bit, only at the peak airflow sections
KFMIRL/KFMIOP leave alone
KFDHBN leave alone as well
KFTARX Set to all 1's
KFDLULS you can increase a little bit, but there's no need for stage 1.

I'm searching for KFMLDMX because according to instructions it's a load limiter and has to be increased.
Further explanations needed please. 10x

Another question that bothers me is why LDRXN is supposed to be limited  to 160.... 160*10+300=1900-1000=0.9bar.
I think that k03-029 can cope with more boost.

Can you tell me what i've missed. 10x

Is it possible to flash 8E0909518AK 0261208230 369307 0004 over my 8E0909518AA 0261207934 366494 0004 due to better definition file. 10x

You didn't leave IRL/IOP alone, you should.  Or use BAM one, it has plenty of load. 

And yes, it can handle more boost - but it's a "stage 1", remember?  Ask for a reasonable amount.  Remember that calculation is rough.

Currently using file from the first post. Corrected Lamfa Colaxis addres and it worked fine. Still car pulls not fluently. Waiting for new laptop battery to take logs. I'm working on BFB .xdf file through this time. 10x for all your replies.

I Flashed the community stage one file onto my bfb and have been running it for nearly a year with no problems  ;)

Hello again. I've managed to put 2 step and antilag php script provided in the forum in my file. Now my question is . Is it ready to upload file to ECU? Are additional settings neccessary. If so, how to define or find maps related to this mod. 10x a lot.

Here is what php script returns. I've checksumed the file after that.

I recently removed the catalyric converter. Now boost spikes to 1.3bar rather than 1.1 before. but I'm losing boost at high end. Do I have to correct something when removing cat exept CDKAT = 0 for not throwing faults? Thanks.

FKHABMN address wanted please.... Anybody???

Here are logs. Car won't boost till 3k rpm. Please Anybody?

MAF readings are very low.  Sort that and re-evaluate.  High timing corrections and lean fueling are likely directly related to that.

PID is doing what it needs to to build boost asap.  Perhaps you have a leak?  Maybe turbo is tired?

How the decat affects these readings? I found that my vacuum jet pump let air flow both ways. Is that related too?

Decat doesn't, but you've adjusted/messed/broken hardware along the way.

Yes I did. But nothing frightening just some vacuum one way valves from which boost was escaping. New logs soon.

Somebody Rate Please. BFBmod4.bin in the logs.rar is the current setup. Do somebody have profile file for 1.8t for EcuXplot. 10x.

I cleaned my MAF. Now it shows maximum of 126g/s. I believe it has been changed by previous owner with such but from another engine. Could anybody verify if it's for my 1.8t BFB engine. Numbers on it are Bosch F 00C 262 049. 10x

IT should be 0986 280 201 as I remember

Looks great except for timing up top. A bit of a boost overshoot, might want to decrease IMX a touch.

Definitely pull timing, you are seeing too much KR timing pull.

Thanks Nyet, I'll consider that ASAP. But what about the MAF why it shows so low values, lower than these from the manufacturer.

I am not sure you looked at the same log file I did.  Nothing about it looked good.  The low MAF readings will cause all sorts of problems due to reduced calculated load.  Get new logs with the cleaned MAF, but 126g/s might still be a bit low.   Consider a new one.

Sorry, didn't look at fuel. Should have.

Lamba control is maxed out. Definitely something wrong. Might not be the MAF, could easily just be a vac leak between maf and turbo inlet.

Thank you so much. After your fast reply I checked the turbo intake hose and found that my cheap ebay BOV, which was supposed to send air both into the atmosphere and  back to inlet hose, has no border between the two exits. So my turbo was sucking air from it (without any filtering :X) and messing with MAF readings.
Now the maf easily reads about 139/140 which is still bothering me that this value is not what it should be.   But thanks to You guys I'm a step closer to perfectly mapping my car.

Don't use a vent to atmosphere BOV, use a recirculation valve like oem!

2nd. Ditch the BOV, you'll have even more MAF issues down the road.

There is zero benefit to BOVs, and in MAF cars, it is doubly stupid because you are venting metered air.

Whoever started this unfortunate fad needs to DIAF.

Haha!  But it goes "beeeeeeeew".  How else will I get the "Beeeeeeeeeews"?

I've installed an LPG system but now I can't make logs. It seems that LPG ecu interferes with cars ECU and ME7logger doesn't work. And do the LPG ECU makes its own timing corrections or I have to change kfzw. 10x

Another noob question from me here. If I flash stock file and log MAF readings, which I expect to be lower than they should be, can I then calibrate it to show maximum of 130g/s ~~~ 163hp. 10x

I found that my MAF is 11% off. Until getting new one I tried to increase MLHFM by 11% but then the car won't idle. Is there a way. Anybody. 10x

Why did you add an LPG system to an ECU you can't even properly mod for a different MAF?

Well, there is only one straight answer....... Money Savings!
Here, Petrol price is over 1.2$ per litter and LPG is barely touching 50 cents per litter.
My MAF is not different. It's the original one the cal lef factory with. It's just old and off correct readings. Info about MAF scaling here covers mostly same MAF diff housing but not diff MAF same housing. That's why I can't still figure it out.

I did another research and what I understood is that I should subtract all Values from MLHFM by 200(MLOFS) then multiply by 11% offset, then add 200. Am I correct? 10x

Yes, that should work.

Didn't work. I think that my offset is not 11% :( New MAF on the way. Thank you all for your help!!!

Searching for help again :(..... New MAF installed, OEM DV installed, turbo checked(perfect condition)... still low MAF readings, even with stock file. It looks like vacuum leak after MAF still. Where to search and how to test. Thanks in advance.

Could somebody take a quick look. It's not raw .csv it's converted... sorry for that but I replaced the original file and lost it. There's not many variables so it's easy to read. 10x in advance!

Here is proper .csv. Anybody please. 10x

You have a good amount of overshoot. Consider reducing IMX

Thank you. I'll consider that :)

Is there somebody that could confirm, this two softwares are crossflashable. Thanks!

Hello after a while. Sorry for bringing life to this topic but I have changed turbo to K04-015 and a proper downpipe. I want to show you some logs, couse I'm not satisfied with what I'm achieving. I've been playing with PID but didn't get what I want so I tried LDRPIDtool.exe and things started to look better. But it's just torque.... after 4k car feels like loosing power. Car runs on LPG tho... but the AFR is good.
Please somebody take a look and give a hint. 10x

Anybody please. Here is another log. My maf is reading low i think. Load is LOW. Any hints will be great. 10x

That actually looks pretty good.

This is good but what about low actual load and MAF?

Not sure how you are determining whether or not it is "low" or not. Your MAF might be a tad underscaled, but your fueling looks like it is compensating for it just fine. In any case, underscaling isn't a bad thing; you're less likely to run into odd limiters that would require even more tuning.

What does it matter if your LTFTs and lamba control is close enough to 1?

Thank you! Big time!!!

What could be the reason for not following requested boost after 5500rpm. I'm unable to find KFLDRQ0,1,2 and if someone could help finding them will be grateful. Should I mess with anything else than IMX and KFLDRL. 10x

Hi doctora90!
The answer is injectors.
I hope you upgrade them in these 5 years.
