hello friend, if you didnt solve your problem yet, load your original dump back and see what happen. If ok, try again, or change km with other calculator (tool). You can also do this dash with tachouniversal (obd) , or use upa programmer with nec adapter, if you like soldering. Trick for opcom is keep the reset km button pressed while programming, good luck
