Hello merc gurus, after some info on which diagnostics tool to get and hoping someone can point me in the right direction My first thought was to get a Icarsoft CR Max (spoken to their representative in the u s and a who confirmed it will work with my motor so that`s good) but then came across things like this: Auto Diagnostic Laptop Toughbook CF-19 TABLET PC with sd connect c4 mb software – Pro Auto Diagnostics . Could i please have your opinion about these?
