Curious to know if anyone's tinkering with the MED17.X ECU yet. I've got a MY2010 GTI I'd like to get to know a little better.  ;)

Yes. But you need expensive hardware to play with it :)

Rick

Okay, I'll play.   :)
How expensive?
Which equipment?
How can I learn more?
I'm fairly motivated and willing to contribute if I'm able.

most genuine tools can do this

magpro
byteshooter
SPI wizard
etc.....

you will not be able to flash it for less than a few thousand USD for tool.

Thank you for the reply.
Do you have any sense whether the cost of the tools will come down with time or is this type of an investment required for anyone seeking to modify the MED 17?

Like many others on here, I'm an enthusiast, not seeking to start a business. Several thousand USD is a significant investment.

Don't expect price to come down for a while unless a clone makes it way to the market with Tricore support.

More thanks!

More n00b questions...
How can I keep informed about clone development? Where do you guys watch to see if anybody's making progress?

what you need to know ?

There are cheaper options for programming ME17.9.7, ME17.9.11, MED17, EDC17.

I am very interested to know what these might be. I'm completely new to ECU modification so speak slowly & use small words, please.  ;)
Truly, I would appreciate all the details you can provide on hardware/software setups required to read, interpret, recode & write data. If there is concern about sharing this broadly, please send me a PM.
Thank you.

pay a big name tuner, dont waste your time.

it will take you 9 months to fully understand how the ecu works, then to start tuning, maybe 40 flashes later you may have something pretty decent.

Im sorry but its not just something you figure out, it will consume your life the med17

Tools....like we said a few thousand, read $4k USD at least.  Then you need winols which will run you ~$2000 USD and the checksum module for MED17 if your Tool doesnt support it.  You should ideally have BDM(jtag) tool to make a total backup of ecu incase you "brick" it as well.

Its a lot man, just being honest with you, not worth it at all, it would be cheaper to ship your car to one of the tuners and have t hem custom tune it for you and send it back before you can invest in just the equipment :/

maybe within a few years tools will become available that are cheaper but nothing i heard or or forseeable future leads me to believe something will hit the market soon

RaraK,
Thank you very much for the reply. It's kind of funny you posted now since I had just come the conclusion that it didn't make sense for me to pursue this any further. While I wish it could be a bit more hobby-ish, it's very clear from what I read on this forum and in other places that MED17 will simply require too much learning & equipment to even simply interpret the OEM code. After that, I'd probably only be dangerous - nowhere near effective or efficient.

Again, I appreciate the frankness and honesty.

hi fletch, can you post the ecu number of your gti?

may be is 1K0907115"XX" ( i see in my country 1K0907115AA )

I am very curious... ::) :-*

Mine is 1K0 907 115 AL.

Like the man said. In the U.K., non 'big-name' tuner Vagcheck (who are essentially a two-man outfit but have a mystery contract code developer who, one imagines, must have good OEM connections) offer MED17 tunes. Morgan comments "This new family of ECUs will be sure to test the skills of our competitors, particularly if trying to achieve the higher outputs as found with our Stage 2 code. Since the whole thermodynamic cycle is modeled within the code, an advanced knowledge of thermodynamics is required to correctly calibrate the associated models & constants."

http://www.audi-sport.net/vb/vagcheck/64970-vagcheck-med17-remaps-tsi-tfsi-special-offer.html

...the whole thermodynamic cycle is modeled in the code?!  :o Just look at the increase in complexity from ME7.x to ME9.x both in terms of sheer number of modules/subroutines and model complexity itself and it's frightening enough. I should imagine the jump again to MED17 is spectacular and would be very difficult to evaluate for an amateur, even with an English funktionsrahmen.

TTQS

The STIG!?!?

I'm realizing that while I aspire to be competent enough to tune my own VW, I probably don't have the available time and energy to crack this ECU.

RaraK's quote is particularly chilling...
"...Im sorry but its not just something you figure out, it will consume your life the med17..."

Thanks all, for the sobering advice. And good luck with your tuning adventures. I'll return to lurkmode.

Just look at MED9. People are still trying new things to get more power out of it.
Stratified injection is a whole another ball game and these ECU's will only keep getting more complex as the years go by.

Check this thread out BTW: http://forums.vwvortex.com/showthread.php?5616176-so-i-dyno-d-my-car-today-to-get-a-baseline.
(MED9)

Yes, the compressor map is moded, so comes into the torque equation :)

Rick

but I disagree with some of the myths about edc17/med17.
of course they are much more complex than 10 years before, but the complexity has two main reasons:
keeping latest emission standards
and
making application easier for the OEMs.

without knowing the details of these ecus in deep, i guess making well drivable tunes stage 1-x is easier than ever before.
but it is more and more difficult to get the map changes in the flash mem of the ECU.

100% correct, equipment to do these ecu's is the major issue.  If you have zero tuning experience with me(d)x then you are going to be in trouble, coming from me7/med9 background, its not terribly difficult, but as said, equipment investment is big $$ not for the amateur tuner to "tinker with"

Indeed the MED17 is more complex, but not impossible at all. Swedens largest tuning company needed a few months to develop both tuned software as well as a hand held computer for programming (I'm sure they looked at CMD/EVC/Optican to get a head start, but never the less...) that the customer receives, so obviously programming can be performed using rather cheap hardware if you want to. They are not gods, just clever people basically... :-)

The later car models (MY10/11/12) are heavily encrypted for OBD-programming (some cars for writing, some for reading and some both) but they can be tuned by opening the ECU, so understanding the MED17 system, and devloping cheap programming tools is obviously not impossible?

See for instance http://en.bsr.se/products/t1574/ and http://en.bsr.se/about/development/

You guys also need the proper documentation. Trying to tune MED9 or MED17 without having the proper knowledge is like trying to make a carburetor work on a diesel engine. (Yes it can be done, but results won't be great).

hi, may be these files, will be help to start for somebody........
i attach files from VW Vento (jetta5) 2.0Tsi MED 17.5 and Gti mk6 with similar ecu
both can be read/write thru obd port

then i attach too a Tprot file readed thru bootmode  for vw vento(jetta6) 2.0Tsi Med 17.5.2.
into the rar i put ecu photo, and captured screen of how to put into bootmode the med 17.5.2

note. i use original CMD flash tool

niice..! so there is a way to read and write these, and not too expensive.. the fun begins! ;D

hi again..........
Med17.5 ecus can be read/write by obd2 port.............

the more cheap tool that i see, is called "powergate", and all clones are in europe, the prices cost for 1 unit its around 500 eur


jpi512

for non TP ECU's, TP you need good pro tool to do though.  Heard of new powergate in works, pwg3 :)  wonder if it will work better for the newer ecu's

PWG3? Where? Who told you this nonsense?  :P

hi, i tested powergate unit on this ecus (MED17.5), and read/write perfect.......

here is a link, to see how it looks. i know that can be cracked. i see the board and have J-tag conectors. may be its posible read micro of one "master unit", then write by jtag to new units "slaves for 1 car only" that are more cheap. i have 3 units.

if any are interest i have photos of board,software, can be ask me here or by PM

jpi

Tool is cheap as it is. Why are you trying to crack it?
Its ~$300USD for a single car version. If you are working on your own car, this is all you need.

Also, there is no tool that will read any MED17 ECU with TP over the OBD2 port as of yet, so please stop spreading false rumors. I have a few Powergate units and they do not work on 2012 VW's with MED17.

hi........
the PG units for single user that i see, only work with crypted files. then you cant use your file. because work in"slave mode". but may be you have another type of PG units............
i work with PG slave units (single user) with some special coustomers......

about rumours, i dont say that PG can work on MED 17.5.2 or newer ecus (tprot). i say that its posible read/write MED17 -17.5 ecus ( i post 2 files )
today i have a vw gti mk6 with med17.5 and read/write perfect by OBD2 with CMD tool, this car is new, year 2012 (in my country). the car have 2 months. at the same time i post one file from vw vento (jetta) 6, that have med17.5.2 (tprot) ecu.with my CMD i can read by obd2, but for write no way "bad seed/key error" then only way is similar BDM system.
i dont have to create here conflicts. only try to colaborate in some way with people that try to play with these new ecus

jpi

OK now I understand. Yes CMD can do 2012 GTI but its also a lot of $$
I wonder why they are always the firsts in cracking ECU's  ::)

PWG has MED17 listed but good luck trying it on a TP ECU.

PS: Sorry for the misunderstanding

So is the CMD tool the only one that can read the full ROM? And yes I know you have to crack the ECU open to use it ;)

Joe

Of course it isn't the only tool that can read the full ROM. Besides, when you read a tricore CPU in boot with CMD, the file you save only shows you the data area, not program code.

Then how do people dump the full ROM?. I have a see an few posted and they have all the different segments. Init, flash, calibration and program?

I though it was done with the CMD tool.

Joe

theres more than one tool for the job, bsl100, cmd, galletto2(not sure), x17.


There are others, like ktag, but it wont read it all out for you, just program data as far as i know.

k-tag read all, or data depends what if you want.
Regards

Thanks for you replies. I think I'm going to bite the bullet and buy a CMD tool.

Joe

I'm sure this is yesterdays news, but it seems like some car manufacturers have closed the door permanently on newer cars. Being a Volvo owner, boot mode is no longer possible on new vehicles.

http://www.evc.de/en/product/bsl/default.asp


In Volvos case, one can always use Volvo original tool VIDA to reprogram the units, but VIDA is very expensive, and is an online tool that requires a service subscription and this is not sold to individuals nor tuning companies so for new Volvo, we have hit a dead end (for now).

im interested in this documentation!!! iwant to know med17 a I have a tuning workshop and I want to improve my files in this ecu
