Does anyone know the seed/key algo for the E37 ecu?? Trying to help a friend over the internet, would make it a lot easier if I could do some of the work here..
Don't need the algo, just the algo number would work for me..

Thanks..

Just had a quick look at a 2008 cobalt & Key is 7B11 & seed I believe is D2BA

Another 2 I just found
Key=8970 & seed=DF09
Key=86B2 & seed=9E28

How many ECU's would use the same code and seed key? Could there be thousands?

Thanks for the seed keys, I'm kind of surprised but I'm having trouble figuring which algo it is, they're all coming back as no matches.. weird.. I'll keep on digging..

If you could post up or send me one of the bins so I could take a look?

Yeah I tried all the common algo calcs I had for LS1, E38, E55, E69, E77 & the E39 which seemed the closest but nothing like those examples I gave you, hopefully the bin files help further!

Anymore seed/keys? Doesnt come up for my system either.

Found 1 more in my files Seed=A403 & Key=9CFE

I'm sure I don't have all the tools y'all do but I did try what I have and I find nothing ...

Am I completely nuts, or did I read somewhere that there were two sets of 2-byte algorithms? There's the set of 256 that were reverse engineered out of TIS2000, and I could have sworn I've seen references to a 2nd 'book' of algos.
