I obviously left it large so you can see the #'s off of it. Tell your father to get a better connection and bigger computer.

Ok so scooby5 appears to be able to read from his microcontroller? Or is he reading from another chip? What pins where you one and what setting did you need to read that scooby5? So other's can know....

Obviously we can read from this, but what about writing? I know we have to translate the dump and figure out what changes do what, but the basic ability to write, do we know how yet?

Anyone here good at reverse engineering exe's? email me if so. I have an idea.

AndyWhittaker have reverse audi rom here

so with a lot (and lot and lot...) of time maybe it's possible reverse (idapro) subby rom :D

@ Subby5 may you send me 2002wrx.h16 ? (pm) tank you

Hi Guys,

I have plenty more stuff but it's on my PC at home and I'm away at the parental units for new years. Expect more stuff early next week!

Sorry for the delay :)

Thats a gold mine of info!!! Ill start writeing the software for my embedded am186 microcontroller. Ill try to make it as easily portable to PC as possable ie. comport modules and what not. But the code itself should be fine as im writeing it in C/C++ and its a 186 anyways so its x86 compatable. We'll see if i can come up with a nice module for the subaru select to post but i duno how soon ill have good time to work on it.

This is a very good first step as from what i understand it may be possible to do raw memory reads over the protocol, i don't know if thats the best way to get the rom image or not but it may be another way.

Hopefully cboles will post exactly how he got the rom image hardware wise and communication wise and we can really get 'hacking' with this project :)

Hi All.

It looks like the initialization for the SSM is a lot easier than OBDII. I was trying to use perl (there's a serial port comm package) to do some of this stuff, but never got it working because of the complicated OBD initialization. Based on what Brendan posted, I might revisit it since you don't need to run odd baudrates to get the thing working.

I'll report back anything I find if I get it working.

Thanks,
Mike

WOOOOOOWOWWWWWWW - THATS WHAT WE NEED!!!!

thank you mumbles!!!!!! lol

I have really fast USB serial- and a ISO OBD2 reader that I am going to try to write some VB code to talk to the comm port and try some stuff out.

I don't know if this will be useful, but I believe that a really simple interface could be developed using the Device::SerialPort and Win32::SerialPort packages for perl. It is really straightforward and the nice things about perl are it is platform independent and it is great for parsing data.

I'm going to be travelling for work next week, so I'll have a bunch of time to sit on the plane and work on this. Does anyone have any suggestions as to what would be useful to include as core functionality? I was thinking of creating a module so that people could take it and use it.

If anyone has interest, please let me know what you would find useful and I'll see what I can do. At the very least, I was thinking about a basic logging tool, but I'm open to suggestions.

Thanks,
Mike

I have a ton of stuff in C++ for the Win32 command line that could easily be ported or rewritten in perl if you have the urge. I just need to clean it up a little bit for general consumption before everyone starts partying on it.

I'm a big fan of linux, so I'd be more than happy to take on the rewrite.

Let me know. I have a long plane ride and need to keep myself amused. :)
