Hi all .. I would like to understand something about these tools, and then I decided to be a guinea pig for them.. and The problem is that (maybe)I have 2 cars no compatible with this. A and a Opel meriva 1.7 101 cv, 2007 should be dense.. The diagnosis autocom sees it as edc30 and diagnosis but no problem with mpps... Nothing... The other, and a bravo 1.9 jtd 105 which should be compatible ( edc15) ,with autocom and socket, 3-pin, everything is ok.. With mpps.. by Connecting the odb all cable adapter is used by autocom to the 3-pin .. Nothing.. I from the ECU is not responding.. what a mistake.. Ps BMW 3 series I managed to read..
