	MED9.1 help « on: March 19, 2014, 09:05:15 AM »

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)

It's half-decent, in the way that it's actually half a tune Cheesy

who did this crap?

I have no logs because I have a boost gauge (makes things easier)

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.

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!

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

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

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

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