Hello all I'm from Brazil and working with light diesel line (Van) do small repairs ECU diesel and what better device for flashing Galletto 4 clone or Kess clone Alexandre
Original Kess V2 works best of all. But since you are talking about clones (which i wouldn't recommend) i would go for the Kess again ONLY if it is EURO clone. Chinese clones pop some errors upon reading through OBD and you have to change some components on the PCB board to be able to work correctly.
