Finally I could go to the workshop and try it. The Dash is not Dash2Pro, is Dash2. Although the menu is similar, I have two problems: 1. When I connect the PC directly to the dash by a serial cable, if I want to read or send the configuration, after a few seconds, the software tell me that It's not possible to continue reading (sending) 2. When I want to change the data source for speed signal, I have this: And when I go to CAN configuration, I have this: However, although is this list doesn't appear any channel, on the dash' screen we see temperatures and pressures (that are connected to the ECU too, not to the Dash), so I'm a little confuse. It's the first time that I configure a system like that so sorry so much if there are many obvious solutions that I've not seen before. Thank you very much for everything.
