ME7Logger would not be hard to do, i basically have the cfg and .ecu parsing running and a KWP2000 HM-2 layer implemented,
but i do not own any VAG car and most likely never will, the ddli hack only applies to them.

Not to give you more work, but ME7Logger will log an ECU sitting on the bench...

I've posted the Volvo DHA tool on here somewhere - take a look at it, you might find it useful. I cobbled together my own logging stuff for P1 and P2 D2 vehicles using information I gleaned from it. I had problems with my host application crashing and not being able to handle too many frames coming back, but it was also combined with the J2534 adapter crashing, so I suspect my J2534 adapter probably is shit. I didn't look any further as I didn't have time to look into the issues I was having any more and managed to get the information I needed, but will probably come back to it when I've another car I need to log.

My ME7.3.1 is on the bench too, winter is coming ;-)

What would be the cheapest ME7Logger compatible ecu to get in the EU ?
The audi v6 ones are like 100+€ too much for somehing i can not use.
Maybe some 1.8T ?

@fluke9

I'm all in on helping get a fully working ME7Logger that works on non-vag roms... I've just done a bit of an upgrade to SAK tool... here's what it can do now... Uploading to github shortly

... and use it as a basic command line disassembler...

In this example using the -d option with address to start from (and optional length).

I'm just adding support for loading a definition file so it can automatically substitute known variable addresses and functions just like IDA does. This means you can literally use it as a poor mans IDA then Wink
