2 simultaneous connections

Hi everyone

I have a question, I have 2 active connections for my dashboard, one is Y-dash and another is speeduino, since the 2 are active, the values ​​they share as RPMs, temperature, are not stable since the values ​​are different.

Is it possible to modify the connection in some way to determine what values ​​are transmitted?

Using two connections that send same data to same inputs will cause ‘value fighting’, and there is currently no way around it.
