Has anyone done any work with this platform? Anything to help me get started? What tools? MPPS clone?

I am in a similar boat with a 2.0T in a 2008 Wolfsburg Jetta.

I have scoured the internet and downloaded lots of things, but haven't had time to really parse any of it.  It looks like the MPPS clones do have trouble in some cases - however the ones manufactured in europe instead of china seem to have less reliability issues.

They also reportedly checksum.

Leaving us to build an XDF.

MPPS works fine in the car, BDM is best for bench writing.

Does anyone know a source of a good MPPS clone? I am not a fan of the "direct from china" sites. Are there any affordable BDM tools?

IMHO it's better to start experiments with MED9 ECU using BDM.
First step make a "photocopy" of original ECU content (Flash/EEPROM/CPU)
Than you can always and anytime 100% recover your ECU to virgin state after any unsuccessfully test und never lost it as "brick".
BDM-100 clones "made in China" are good reliable and affordable.   

Gremlin, what do you think about this?

Thanks!

I bought for experiments visual exactly the same box. It works.
IMHO this box (maybe this concern only my version of box) has one issue.
It have relay inside witch is switched directly from USB supply current.
This may cause аn overcurrent problem for some notebook USB-ports. 

Look inside...

Interesting...  Well, I am going to order it!  Let the games begin!

Is the adapter from the second link needed?

I am not sure.  I was trying to get better pics of the small "adapter PCB's" they include in the kit.  I may have found a source in the US for the BDM100 clone - if it is the latest version I'll post up the info.

Great. Thank you. We need to start a trusted sources/sites list.

To deal with MED9.x or any other types ECUs manufactured by Bosch you don't need any of adapter PCB's.
Adapters are using for ECUs made by another manufacturers (Siemens, Marelli, Motorola)
Spring-loaded pins adapter will be useful for Bosch ECUs to connect BDM without soldering. 

Usualy Bosch ECU BDM-port looks on PCB as follows...

10-4...

So does anybody know of a better place to buy a spring loaded pin adapter than from overseas?  There has to be something from digi-key.  Unfortunately I am not well versed in all these connectors so I don't really know what to search for.

Try searching for "pogo pins". To get that working you'll need a nice stand and clamp and a lot of work into those...unless you're planning on doing hundreds of ECUs I'd say just try and solder on some pin headers to the bdm pads....should only take a few moments.

Be careful soldering pin headers.  I have a fair bit of soldering experience, and on some of these Bosch ECU's the pads don't seem to be made very well - being about 0.000001mm thick - they disintegrate as soon as you touch a hot iron onto them!

I would go for pogo pins, but then you need to spend 2-300 on a BDM frame.

Note, that the BDM100 clone - the latest software is 1255, which is from 2006 - so u can't flash anything newer :(

Rick

noooooooo!  I ordered a clone and my ECU is a 2008 :(

Don't worry...
Bosch MED9.1 ECU family for 2.0TFSI engines is fully hardware equal from 2005 up to 2008.
You'll read/write 2008 ECU without any issues.
 

woohoo!  That is what I was hoping....

I've been trying to wrap my head around the best way to build a fixture for the BDM.

Here are some of the homebrew setups I've found:

http://www.digital-kaos.co.uk/forums/f173/bdm-positioning-frame-made-house-210704/?highlight=BDM100

If you need to be registered to view I can rehost the images.

Here is where I sit (thoughts, feedback, criticism is appreciated!):

Ordered an MPPS from the US, ordered POGO pins from the US, and ordered the BDM100 from the US.

Ordered a spare working ECU for a whopping $150.

First order of business will be building another bench harness, or adapting my S4's harness.  Once I verify the ECU is working on the bench, I will do a BDM backup, and then restore the ECU, and verify functionality.  Then I will test the MPPS tool, etc.

Once that is done, I will dump the ECU out of the car, restore it to the spare ECU, and then put the spare ECU in the car to verify it works.  Then I will try MPPS flashing in the car.  If all is well, I will be ready for tuning.

"From the US" = is now in the US because it was sent there from China....

Don't be afraid to solder on the pin headers...I suck at soldering and I had no problems, just take your time.

Here's a quick hint to save some heartache of having to BDM your original ECU/set up a BDM stand/solder, etc:

Read out your ori ECU EEPROM on the board with a SOIC8 clip. Then take the ori ECU and read the flash with MPPS. You can then import both of these into your BDM software and then you only have to worry about setting up BDM on your "spare" ECU. Might save some trouble.

I too soldered headers on for my BDM, i had no issues at all.  Assuming you have a decent soldering iron station.

Thom,

I see you have been down this road before, do you have anything to share, publicly or privately, in regards to map locations.  I have been successful in finding a handful, but i do not have a proper definition file/hex that is compatible right now(or i am missing something)

You're probably not "missing" anything in particular. The one .a2l and hex floating around right now is decent, but it has some very different setups for the maps.  Just takes a bit of poking around. If you have any questions I can try to answer...its a bit frustrating though to put lots of hours into something and then just hand it out like candy...especially when some people (not saying this is you) will take it as there own , sell it, and then be unwilling to give anything back (information/etc).

Are the boxes interchangeable or somewhat interchangeable like they are on the S4 platform?

Is the ols/a2l you're talking about from the A3?

I'm curious to know if Spen's utility can take the a2l and use that as a base for finding maps in my 1K0907115S

The A3 A2L is the only thing I have seen around. I tried to upload it here, but I kept getting an error. I don't have the DAMOS/A2L plugin for WinOls , so I couldn't even view it.

On another note, I have a spare ECU on the way, 8E1910115X 2007 A4 2.0 TFSI.

I have a spare on the way as well. This is what I have:

D9156_41R238.a2l
fsi.2.ols
2.0tfsi.ols
0261B00486.bin

The US based (maryland) company selling the BDM sucks.  I ordered last Sunday, paid for premium shipping, and it hasn't arrived yet.

I got my Pogo pins the next day, from this guy:

http://shop.ebay.com/pingf123/m.html?_nkw=&_armrs=1&_from=&_ipg=

I also got an MPPS clone, which I need to play with.  I saw there are a few people who have figured out how to update it as well.

Thom,

I have found ~20 maps that i believe are to be edited, is this on par what you have found to be true?

My definition is not yet complete, however i should have one up within a week for the base maps to tune, others to be found would be on your own.

The def will be for the med9 file i posted a few weeks back.

Is it safe to assume that we should be able to identify these maps in other ECU's based on the maps being offset?

yes,

one thing i noticed so far, bts has two maps in damos in this one section, i find four in mine....gotta keep digging and reading.....

heres where i am thus far

I got my spare ECU today so I will do a BDM dump and post that up ASAP.  Looks like it may already have a tune on it, although I'm not entirely sure.  There is a "not factory" sticker on the outside that has weathered..

I hope to purchase a bdm soon... i'll be able to help the cause.... a.k.a. asking stupid questions.
I came across a stock s3 bin... if it's helpful i'll post it up later

I posted the BDM dump from my junkyard ECU here including serial eeprom.

http://nefariousmotorsports.com/forum/index.php/topic,888.0title,.html

Definitely not a bad starting place...I guess all the maps you need depend on what you're shooting for. You might also check out cam adjustment target and rail pressure demands. Also, there should be a few more maps all in a row for the LDR PID. I see one or two. In the area where you have your spark maps...how many total do you see? It looks like the A4 might be set up differently...possibly for different variant codings...

Which .a2l/.dam/.ols are you using for this one?

a2l i was given from another member, i dont have a very matching damos, so im reading through with asap2 editor, and just knowing what maps look like from me7 ive been finding what i need, i really didnt have a whole bunch of issues thus far.


Yes there are many other maps in the area, i am just grabbing key maps thus far that will be required for a stg1 tune.

I have not had a lot of time to work on this due to me7 business and trying to get my M3 turbo in action

Oh and btw, its got the rough tune done, my car threw a CEL for lean conditions! great....so off to the dealer it goes to get repaired(under warranty) so im not going to be able to test this for another week at least :(

Fuel cut I presume? Have you checked your lifter/tripple cam lately?

Whats the filename of the .a2l you have?

yea i presume its that...blah i dont give a heck. its CPO, so the dealer can deal with it, i bought the car so i dont have to work on it :)  i have my bmw to play with :)

but anyways   d95036_sn6iau00.a2l

i have another one too which is better.

and i have some GM ME9 files i use as well which are full matching damos.

Check MWB 230 / 231 for Fuel Pump Issues

isues are not tune related, i havent flashed it yet! i was about to flash it last saturday and start tuning it in, and friday night on my way home from the bar i got the CEL :(  so its bone stock right now.

do i need no external power for this bdm100?

Guys,

is this any use to you?

Rick

Thanks,
I can't wait to get it up on my laptop and take a look.

Most BDM clones come with an external power supply.

Mine did not :(

So can anyone experienced tell me about homogeneous mode, stratified mode, supposedly stratified mode was never fully implemented in mk5 2.0tfsi's(from what i hear).  There are timing maps for open and closed charge-movement flap/valve(flapper on intake manifold?). You can find the keyword LBK in the FDEF i posted regarding this.  I feel that what i read is very general, and there is a lot of info in regards to different control strategies and different coding's that are available for the platform.  What is used however, i do not know yet.

Any insight?

Was the ols file I posted any good?

Rick

Anything new with this?

did you get it working?
all BDM clones I see in ebay/china are selling it without Bosch plate but with Siemens, marelli etc.

That's because you just need a JTAG adapter.  I spent $20 making one, because I am a moron and didn't see they were only $14 premade.

Here is the one I made:

(http://i.imgur.com/ydAnK.jpg)

With the ECU's giant harness connector facing AWAY from you, pin 1 is on the LEFT of the JTAG pad.

Is anybody know something about MED9 functionrahmen, like for me7? I hear that this is about 8000 pages pdf file...And what is normal price for this document?

Sorry for offtopic, but this is the only med-related topic that i can found here...

I posted it already

http://nefariousmotorsports.com/forum/index.php/topic,812.0.html (http://nefariousmotorsports.com/forum/index.php/topic,812.0.html)

Thank you very much!!!

OK, back on track kinda....

Who knows about IMMO4 and when it went to IMMO4a(crypt)  split on the tsi motor? or is it a year/vin based thing?

that 0.1 inch(?) spacing of that ebay part is the right for Bosch?

Did you already get your assemble working?

Yes, and Jason and I both have "ebay BDM's" working fine.

what about this adapter?

http://cgi.ebay.com/ebaymotors/BDM-100-ECU-spring-loaded-probe-adapter-12-position-/250473213741?pt=Motors_Automotive_Tools&hash=item3a515def2d

wrong one for bosch ecu's?

That one should work just fine.

Hope, so am I very soon. ;)

Anyone working on this project, can you make sure you post all .bin's you have(stock) so i can use for comparison.

so far....

2005 VAG 2.0tfsi 6MT has some map differences from my 06 GLI DSG, major differences, such as no kfmirls, where as the 6MT files have kfmirl and kfmirls.

I currently cap load at around 165...im missing something.  May be dsg related? there may be some maps that limit load.  I found some load related maps, but they appear to be sufficient for my current state of tune.  So i am unsure of the issue at the moment except im missing something with the load calibrations.

What do you mean cap load? On your KFMIRL or on the charge limiter? It should start to be apparent that the entire torque mapping will have to be restructured at some point as the scaling of indicated torque % vs charge % can only be increased a little before requiring rescale.

Well i rescaled from 150 to 160 with no differences last night.

The cap i mean, is it will not request more than 165 at this point.  Though its calibrated for a theoretical higher limit. 

I will fully scale it up to around 200 and see what i get next time around.

Its funny how on this same basic setup on me7, it works a treat, maps are surprisingly similar in some respects.

keep on keeping on.....

Slightly OT, but the Golf 5 doesn't use stratified charge mode does it?

Rick

a friend says no, though vw documents it does in dealer training material supposedly. IDK

Not in the US.

Thank you robin. 

I don't think it uses lean homogeneous either as there is no NOx storage tank.  So I don't think it ever runs leaner than lambda 1.  This will make it a lot easier to tune, i'm guessing it'll be the returnless fuel system which will be the biggest change from ME7 tuning.

Rick

So what tools work well for BDM?  I need to be able to do MED9.x ecu through BDM and I'm shopping for what tool to buy.  I see a few of you have bought a clone and have it working well.  What one and where did you get it?  I have a MPPS clone and it doesn't seem to work at all.

im wondering the same thing... would like to get one soon

For a good Stage 2 tune, you may need to mod anywhere from 50 to 100 maps  :-\

Can someone verify what is needed for the 12v external power supply, I got a clone bdm100 that did not come with one.  Im assuming I need that in order to read/write the ECU in my 06 A3.  I believe this is very similar to mkiv gti.  Inside the ECU it had the 14 pad layout near the back, is it true that only 10 pins are needed?

12v, 1 amp. Yes, 10 pins.

Thanks!  This will be tons of fun. ;D
