Why dont we have something like this for Audi's?

Rumour has it that a few people were able to crack the VW ECU code.. and create there own "file"

Yeah, they're called APR, GIAC and Revo! LOL. There are more open source ECU programs out there. I haven't check on the VW's yet.

[Redgoat]

Well I was talking something more along the lines of fully custom tune

[koolade9]

Most people that hack the ecu start thier own tuning company, as they don't want to give out their software to everyone... Other makes have this available for a cost...and it's a great thing: dsmlink, hondata, etc... I'd love to see it for our cars!

That sounds, a lot more complicated, doesn't Revo offer custom tuning?

Understandable, seeing as the other guys charge $500 to simply flash the EEPROM.

we have a few applications that can extract the map from our ECU's. but none are user friendly.

and you have to look through binary code to separate the maps, then do conversions. its really a pain in the ass.

That sounds like a fun way to spend a sunday afternoon

Coding? No, thanks! LOL

[Redgoat]

yeah.. totally sarcastic

[turbo kraut]

i have a buddy that has a giac and apr software on his laptop....... i think he said it is a hacked version of the program that your local tunner shop uses to flash your car

only problem with that is...... if something goes wrong with your car after a flash don't you want someone to be liable?

[Redgoat]

well think about it with REVO if your using lemmiwinks or playing with settings.. your liable. So what not have more control?

[BARRY]

from what i know of it. everybody who installs REVO, APR, etc etc. they don't tune your car. they just load a map and make sure it runs good. Even the people that install the maps don't even have access to modifying the maps.

I think Revo allows you to change the map, e.g. as in while you are on a dyno. But APR is locked, that's for sure.

You can download ME7(Motronic) firmware for the 1.8T out on yonder interweb, then grab a copy of WinOLS(easy way) or your favorite hex editor(hard way) and go to town.

Everything you need to extract, write and burn code can be found there...

Remember the guys who do this for a living are people just like you and I.

definately, if you can identify the correct fuel and timing maps you're set, but like with the STi/WRX ecu's the ecu contains multiple maps i assume. the problem would be determining which does what and how it translates to the correct load values.

going along with that it would be rather difficult to identify the smaller maps like fuel enrichment, idle motor, temperature compensation, or bypass of the MAF.

I have been trying to contact some development teams to see if they could build me a translation map but nobody wants to touch our ECU. all we need is the translation map that pares the separate maps for us. then all you need to do is modify the map and reload and you're set. still not as good as a software that works realtime and changes happen realtime, but it is a start.

Have you looked at WinOLS? It has an "automatic map search" feature that might be of use to you. I've only played with it briefly, but it looks to have potential.

Seems like you have to be in the industry to get into there forum

actually motronic is pretty easy to figure out. i spent a few days and mapped out my 01.5 motronic and if you are a "warez dood" you can probably find winols which will take care of the motronic checksum(s).

comparing the stock chip to a modded one makes it real obvious whats going on and having the understanding how our motronic works definitely helps too.

i think what you won't find is flash loading, but if you can get your stock chip socketed you could easily get a burner (needhams EMP) and some blanks AM29F800B and go to town.

just remember tuning is not as fun as might seem to be. the hundreds of hours the tuners have honed their chips; you'll be starting over re-inventing the wheel.

if you can get some hardcore motronic hackers they could probably add some elite functionality like the honda folks do like launch control if that has any interest to you.

i was thinking of plaing with the 1.8T B6 now that its not a primary car. not necessarily for power but for more functionality. more so in the tiptronic department is my interest..

[Redgoat]

Is there a method to read/write your ECU image from your car??

[A4TL]

nothing public domain for the obd-2 port. using a socketed flash rom no problems..

i do have winols, and another application, which i forgot the name.

neither are worth while. you can use another program which i forgot the name to download, and upload rom images to your ecu.

no need to chip, you just need to have the right software to do so, that being said i don't know if it is compatible with my basic obd2-usb adapter.

i would have played around a little bit more, but i as well use this car as my primary car. on top of that, it is apr flashed, so i need to locate a replacement ecu for the playing around portion. i'm sure i can find someone to map out a translation map for the downloaded rom, but the point is i don't think anybody is willing to put the time and effort into developing a application specific application. i have tried contacting a few people, but nobody is intersted in fooling around with an audi. the thing is vw, audi, seat, volvo, etc etc the list goes on. all these use practically the same ecu, the possibilities are endless once the motronic ecu is unlocked.

this is something i would definately pay for as a tuner.

so youre saying if i wanted to dyno tune my APR K04, that I wouldnt be able to tweak the programming/fuel/timing?

From talking with people that have actually figured out the Audi/VW coding and know how to tune a car (and tune cars) the Bosch systems are very complex. Extremely complex relative to Hondas and Subies.. That is why only a handful of companies offer tunes for our vehicles. That is why an even smaller handful of companies offer custom tunes for our vehicles. It has taken them (people like you and I as Greg mentioned) many hours and days and months to figure out how the ECU operates. You change one map but have to cross reference it with dozens others since it is called from various sources and situations. Due to that time invested it is wise for these individuals to keep their secrets to themselves and start a business out of it (niche market). That is why you do not see open source coding for Audis/VWs like you do for Subarus and the like.

Sure, you can go ahead and try and figure it out. No one is stopping you. However it is most likely time and money better spent going to one of these handful of 'tuners' and having them do it. (Unless you like the challenge).

My suggestion (which I've been doing) is to better understand the basics of how the vehicle operates to troubleshoot issues and understand why your vehicle is doing what it is doing. Do some logs with Vag-COM and see what's going on. Stuff like that.

Cheers!

Try Vag-com, Lemmiwinks or Apr V-tune and you can do it all your self if your not interested in what everyone else is saying.

I second this approach. So much so, that I'm going to try my hand at a homebrew EFI setup for my lawnmower if I can find an injector small enough (2.5HP single cylinder Briggs&Stratton powered pushmower). I want to learn more about how all the sensors work together, and it's the cheapest/most practical test platform. It'll be the only fuel injected lawnmower in the neighborhood, that's for sure. Anyone know where to get a -really small- turbo?
