Re: EDC15C7 - Alfa 1.9 JTD Euro3

I tried all the other requestSeed parameter .... but the only
that replied with a valid answer is $01.

I still don't know the algo used .... but I already discovered
several ones .... I hope that it's similar to another one.

But first of all I need to get some valid seed&key :P
