Hello all,
I almost have all of my answers to start my Virtual Instrument cluster project.
I am going to design a circuit board to connect to an original (second hand) cluster. Then I'll mount a (touch)screen in the place where the dials are now and mount a bar with lights on the top of the cluster to get all the warning lights and indicators, because it is almost impossible to get that also from the OBD2 protocol/CAN protocol. On the screen it will show all my dials, gauges and graphs, like Speed, RPM, Coolant temp, fuel level, turbo boost pressure, fuel level, etc. Even navigation will be shown on the screen.
All of that info I will retreive from the OBD2 port and protocol. This is why I have the following question:
- My virtual dashboard is connected to the OBD2 port and it will use that Protocol. When I have my MOT or other maintenance, they need acces to the OBD2 as well. If I split the OBD2 port with a "Y" cable (all wires populated) and plug my OBD2 dongle (like OBDlink, ELM327, etc.) in and leave the other end available for the mechanics, will this work?
It would be a pitty if I/the mechanic has to disconnect the instrument cluster every time some diagnostics have to be done on my car.
