Hi guys,

I've just read out my ecu (MED9.1) and it looks like my car was mapped before (based on the flash counter).
Thanks to jordan, i've a golf R bin file to compare to but when i load the map-pack jordan provided into my bin file, the address are different. Why is that so?
I've attached my bin file, can any kind soul help me and take a look at it and see if its decent? (because its not making any decent power)

(https://lh4.googleusercontent.com/-eWiwoTuB7JY/Uym-lwyP4FI/AAAAAAAACDs/TIst2l9sxuQ/s640/KFMIOPS.jpg)

It's half-decent, in the way that it's actually half a tune :D who did this crap?

There is a checksum error as well.

Some 'tuner' in my country which the previous owner paid 2k for.. Can you elaborate why is it half decent?

Hmmm.. If it has a checksum error, how was it flashed in and able to start? Thats weird..

Can anybody enlighten me why jordan's map-pack didnt work on my bin file?

How did you all get the maps out so quickly? I've spent the whole of today and i still cant see what maps were changed. Can somebody throw me a bone?

It is probably another software version than the other you have got the map pack for. To me it looks like it would match fine if you import it with an offset of -2.

In WinOLS you can work with versions of the same map. You should find an original map similar to your software version, that would make it easy to see what is changed.

Vw version:  1k8907115d
Bosch version:  1037504148


When u say software version,  r u refering to vw or bosch? I've a dsg so i guess there might be slight differences? I'll try with "-2" offset and report back. Thanks for the tip!

I've tried the offset but couldnt get the maps to line up, anymore spoon feeding, plsssssssssssssssssss....

maybe make the map pack so you understand the ecu more rather than having someone supply you one?

oh BURN!!! hahahaha

hint: search function - search for groups rather then one single value

Yeah, i definitely agree with you and i went through your prev post on how to kickstart a couple of times and its starting to make a little sense to me now.


I got yr hint, i was looking for maps w/o loading any map packs thus i was having problems finding maps.

Thanks for the replies guys, im really just starting out on getting to know the basics of tuning so please bear with my stupid questions.
Having spent another 2 days on it, im beginning to get the hang on using winols and had already got a few maps out with reference to jordan's bin file.

I understand that LDRXN maps are used to specify max load but why are there 6 LDRXN maps?
1 map for each gear?

Ignore the strikeout above, i left it there in case someone needs it.
I've found the answer to the 6 LDRXN maps in the link >> http://nefariousmotorsports.com/forum/index.php?topic=1770.0

FYI- so far from my dissasembly work it seems the first ldrxn is the only one referenced. The others are never read at all. This is in my golf r file. I think the other med9 file in using has three ldrxn maps and they ARE used. But in our case, only the first istouched

You sure they're not switched with VARDEF?

My golfR is DSG-ed and it comes with DCC, i'll try to change the LDRXN files and see if its reflected in the logs.

It's possible I missed something but I'm pretty confident they aren't used. There is a global variable that references each ldrxn. Only the first global variable is ever used.

I finally understood your meaning of offset-ing the damos/map-pack import with a certain offset, by the way, the offset was 2200 (hex).
Not sure how many out there would be as noob as me but i figured that i should just jot it down here and it might come in handy for someone someday.
This might not be the best way but its 1 of the way to get the offset value.

Steps to find the offset in importing damos/map-pack
1. Choose a known file in the map (i chose LDRXN1 because its easy to spot in the 2D view)
2. Define the map (press 'K')
3. Look under the address column (in my case, LDRXN1 is on 1CFAFE) and take note of the address
(https://lh6.googleusercontent.com/-pdDJi8CYScc/UzBtT0Y-ImI/AAAAAAAACEs/xWJGPyV9VZE/s288/import-mappack-address.JPG)

4. Import the damos/map-pack and search (CTRL + F) for LDRXN and take note of the address
5. Now u'll have 2 address of LDRXN, 1 from step 3 and the other from step 4
6. Open the windows calculator, go to 'view' and then 'programmer'
7. Select 'HEX' and punch in the address from step 3 and minus it from the address in step 4
8. Hit equal and that'll be the offset to import damos/map-pack
9. Key the value as-is into the import dialog and hit ok
(https://lh5.googleusercontent.com/-gx2sV9yFVPU/UzBtTUBPz9I/AAAAAAAACEk/ghFz4r3GKto/s288/import-mappack-offset.JPG)

10. u've now aligned the damos/map-pack to your bin file

Does any of the following disable evap altogether?

LAMTEMN - minimum of lambda threshold for canister purge control active
CWEVAPDEN

In the country where im in, we run into lots of CEL over damaged charcoal canisters/n80 valves.
If i can find a way to do an 'evap delete', we'll be very happy!

Anybody can teach me how to scale an axis?
Im trying to scale the load axis for hours and im no where, i've googled and searched but still nothing..

i finally figured it out, its as easy as highlighting the value you want to change on the axis and hit the +/- key!
I feel so dumb to had wasted a few hours on this!

I've edited the LAMFA, LDRXN, KFZW, KFMIRL and KFMIOP tables to reflect the load that im going to run on.

Changes done
change LDPBN to 2550 for all
change KFZW to be like jordan
change KFMIOP to max load of 215 at 90% TP
change KFMIRL to max load of 215 at 90% TP
change LDRXN to load of 215 at 6800rpm and estimated the load values from 2250 onwards
change LAMFA to -3% for all

I've followed Jordan's lead on the timing value for a start until i run a log.
Comments pls, does it look safe and decent for me to do a log session?

I notice that in VCDS, the throttle position is always at 99.6% but im still using 90% in the maps, does that mean that when it is at 90% throttle the load will be 215 and by 99.6% throttle, the load will be higher?

Load will not be higher than your 215. Over 90% throttle it just uses the last row values.

Is be careful with the timing. I was pretty aggressive I think. I actually pulled it back some recently.

The lamfa changes aren't going to change anything.  The med9 has a very low bts threshold and from what I can tell is designed to run bts fueling under heavy load (though I could be wrong). I dialed back the kflbts map a bit as it's Realllly rich from the factory.

Y wouldnt e load be over 215?

Because your last kfmirl coloumn is 215.(I am not sure, just my understanding - i am a total newbie)

correct

Oh yes, i do knw tat load will not be over 215 because i want to cap it at 215 for now and see how it looks like.  I do not want to go 230 and worry that something's gonna break.

215 load is definitely achievable rite? What would be a good load if not 215? I've seen people recommending 232 but i do not want to follow blindly.

There's also an 'equation or some sort that will calculate estimated boost when u use a certain load,  how does that work?

I think they say ((load *10)+300)-1000 = boost in mbar approximately

Thanks for e formula jordan.

That doesnt look rite.. If i plug the numbers in, it'll be like 1.1bar and i shd revise load to be higher as i knw tat my k04 mk5 gti used to run 1.6bar of boost..

The above formula is theoritical, just to get  an idea. There is a lot of parameters(corrections or limits) which involved for  the total result.

True! And that formula does not come close to anything that I ever logged on my MED9.1 TFSI. Something around 210 load usually gets me to 2550mbar which is the maximum that can be requested AFAIK.

Ok, sounds like my load is a little high but it should be fine.
I hope that i would nt get torque intervention since the max values are pretty close to each other.

Any other issues with my changes?

Im comparing a defined bin file by automan001 and it looks like the golfR has 3x the map compared to the 8P audi A3.

(https://lh6.googleusercontent.com/-mo1bYe3uVFU/UzIVAp7xluI/AAAAAAAACGQ/IFAI8OdJUeE/s800/finding-KFLBTS.JPG)

So,
KFFDLBTS(a) will be used for KFLBTS(1)
KFFDLBTS(b) will be used for KFLBTS(2)
KFFDLBTS(c) will be used for KFLBTS(3)

Did i get the KFLBTS maps right?
Im assuming that the 3 sets of maps corresponds to 3 variants as well?

I've DCC on my DSG golfR, maybe this could be used to sharpen up the throttle response?
Throttle response is done via KFPED

Just to show how rich AFR is.
Picture on top is the golfR and the bottom is A38P i guess.
(https://lh4.googleusercontent.com/-_zfJhA_nrYQ/UzI81sYDL6I/AAAAAAAACGw/MYa65OoY1bk/s800/compare-KFLBTS.JPG)

Does modifying KFLBTS affects AFR directly or do i have to modify another map in conjunction with KFLBTS since KFLBTS is a component protection map??

Thanks!!

KFPED

I've yet to load my 1st version of map into my car because im waiting on changing the section where it controls the throttle response.
Im after a snappy 'REV*/G*AC' type of response because in my country, its a lot of stop-go traffic.

As i've read:

IRL seems to have a part to play in the throttle response goal but KFPED seems to be the one that i should be editing.
I ran a simple log on "idling specified load" on my ride and its around 31 so i started off with 31 @ (400,2.50) which <masterj recommended> and guestimate throughout the map.
I've read from somewhere that the x axis of IRL is KFPED so if i +% in the KFPED map, i should have a better throttle response right?

Anybody with inputs to my KFPED question?

Before i load my 1st flash, i know that i need to run a checksum on the bin file. I've tried the med9.1 checksum tool and it returns a 4kb eeprom so im unsure how to flash my bin file into my car. Any pointers on this?

That tool is just for the EEPROM. You can do it with winOLS. If you don't have the med9 checksum plugin for winols I can correct thrm for you.

You should checksum your flash, not your eeprom

Edit: oldcarguy was quicker ;)

Thanks for e replies guys!
I'll try and look at my version of winols and see if i've the checksum plugin. Thanks for offering to checksum for me jordan!

Can someone verify if i exported and checksum my changes correctly?
Thanks in advance..

CHKS is ok

Cool, thanks TC!
Can i assume tat i can flash this into my car right away?

Just do it :P Most tools correct the checksum in writing anyway.

KFMIOP is interesting in MED9.

Personally i see no difference between having the max load in KFMIOP at 180 or 280.

I dont use the N75 so this may effect things but there is a massive discussion all the time about KFMIOP and KFMIRL.

You will need to change KFMIRL, no question.

KFMIOP is interesting, my value in the last load line is changed to 99% but it makes no difference if the axis is 180 or 280. 500+HP everyday. GTX3071 2.0 TFSI.

I by no means think im an expert, im learning a lot everyday. Anyone have thoughts on this?

Its been a while and im still tinkering with my 'stage 1' map. I've came across DIMSPORT and RACE2000 software which i use to edit the maps but the axis is totally off on the RACE2000 software so i had to resort to using WINOLS and RACE2000 at the same time (RACE2000 is easy to use because it plots the graph based on the values you change in real time).

Im still trying to find the changes that suits my driving style and it looks like by editing most of the fields in IOP and IRL, it made the drive smoother and perky. However i am running into rough idling and random misfires.

Here's a section of the log that i did during normal driving and its going as high as -6!

Questions
1. Do i need to retard (reduce) the timing in KFZW to get rid of the timing pull and rough idling?
2. Can i raise the values in LDPBN from 2550 to 2920 since the actual boost is 2920 @ 3600RPM?

(https://lh6.googleusercontent.com/-qOj9ZSRrq8k/U-kG0gW2I9I/AAAAAAAACQo/8ezlL98kxh4/s800/v6-pulling-timing.JPG)

Please post proper logs (original csvs) or ECUxPlot graphs.

1.6 bar of boost or 2.6 bar of boost?

Do you know why that equations has the "-1000" in it?

Please, step back a moment and understand what load is :/

There is so much terrible information in this thread, I wish i'd spotted it sooner.

Im actually hesitant to do a log-run on the car knowing that its pulling so much timing but heck, i'll do 1 tomorrow and post e bin up as well..

Its 1.6 bar, i did not subtract atom pressure off the column.
Terrible information? Care to point some out?

Start with your target max load.

Why did you pick 215?

I've changed it to 190, e previous screenshots u see was what i went with initially. I should had posted e bin and some 'correct' logs up when i asked for help. Apologies on that..

Im going with 190 because ((load *10)+300)-1000 = boost in mbar approximately and although im not gonna get exactly 1.2bars but thats e minimum that i wish to be boosting to..

My advice would be to put IOP back to stock, and to not worry about torque intervention unless you actually log it.

Keep IRL mostly stock (like you said you did).

I wouldn't mess with KFPED either, until the rest of the tune is solid. Do it last. It is irrelevant at this point.

so how do adjust maps to request 1.5bar of boost? you don't go to 215 load? just wondering your process with the med9

I don't know enough about MED9 to say, but what is the limit of the MAP sensor?

By 1.6 bar, do you mean 2600 mbar?

1.5bar and yes 2500mbar. map limit is the same at 2550mbar

I thought golfR's MAP sensor is limited at 3bars?

I can use 215 load to get 1.5bar of boost but as it is currently with 190 load, i am already exceeding that (1.9bar) so i can stick to 190 load and not change the axis on IOP & IRL? Is my understanding wrong/incomplete?

LDPBN is an 8bit value and can not be set any higher than 255 / 11111111.

I am wondering why you see such high boost spikes. Have you been doing any changes to the PID in the SW or the wastegate/actuator? Do you have 190 as the highest value in IRL and LDRXN?

The K04 equipped cars have a 3bar sensor. But that does not mean that they can request more than 2550mbar anyway.

Got it, thanks for the lesson.
Anyway i found that hopping between race2000 and winols retained the load at 215 in LDRXN and i also found that 214.43 was the highest value defined in my stock IRL.
Nyet, i guess that also answered your question for me as well.

Stock IOP & IRL
(https://lh3.googleusercontent.com/-LYsj-Ra4oUA/U-nhXGp1cPI/AAAAAAAACS8/sHteEzLesYc/s800/stock-IRL-IOP.JPG)

Ok, here's me starting afresh from a stock map with the changes below and i'll do some logging if the weather permits.
Just a question, do i need to change the axis in KFZW to coincide with the axis change in IOP?

LDPBN
- 2550 all round

IRL
- 215 at 90 load

IOP
- change last load row axis to 215 and used 90 as value throughout
- removed 120 load axis
- shifted 150 load axis up 1 row to replace the original row of 120 load with 150 load values
- shifted 180 load axis up 1 row to replace the original row of 150 load with 180 load values

KFZW
- -0.75 from rpm(3520,6520) and load(150-190)
- do i need to change the axis here to coincide with the axis change in IOP?

Rescale the KFZW axis to coincide with the load you'll be seeing. It doesn't necessarily have to match KFMIOP, just try to make the most use of it.

After a break, i'm starting afresh in pursue of the stage 1 that is tailored to my liking.
But i still have somethings that i cant figure out, i've attached logs and my work.

1. Which map should i adjust to increase the rail pressure?
2. Why didnt my AFR follow BTS?
3. Why boost doesnt seem to follow specified after 5040RPM?
4. Why does the load decrease after 5080RPM? What should i do if i want it to maintain above/remain at 191.7?

Any hints/help would be very much appreciated!  :) :)

First, I have not opened your file. ;)

1. Take a look at the KFPRSOLxxx and KLPRxxx maps.
2. Are you expecting it to follow KFLBTS? Have you changed DLBTS or KFFDLBTS? The BTS target calculation is not based on KFLBTS only.
3. You request more than the turbo is capable of.
4. Same as 3.

In your logs it also looks like you have been doing something to your LAMFA maps? Specified should be 1.00 under light load and idle.

Have you checked your MAF readings?

In the log you posted they make absolutely no sense.

At 3240rpm it reads 127.31g/s and at 3360rpm 198.72g/s.
It is just not possible.

Also you are making far too much torque at too low rpms.
1.76 bar of boost is a rod killer when the rpms are so low (3300rpm).

The engine is running way too rich from 3500rpm and up.
You could easily make it leaner by 0.1 as the optimal is between 0.85 - 0.8.

In few spots you are already getting torque intervention as the lambda exceeds the protection threshold (actual is 0.04 greater than requested).

I´m no guru but I would personally start making a new software from scratch.
The current one is not safe to run IMO.

You're right, i was working on my previously modded file with LAMFA edited!
I guess that accounts for my bad FC.
Thanks man!

I find my MAF reading weird as well, i've originalized the LAMFA map.
I've italian set KFLDHBN to 2.5bars, it shouldnt hit the rod breaking boost this time round.
Gonna log it again and see if i hit anything near to the AFR specified in KFLBTS.
Thanks for the hint.

And that was the last we ever heard from ol' weijie..
