I got VSS working on realdash through Serial3. Again this is what I have to do because I can’t load any files to realdash.
So in Speeduino folder find file :
cancomms.ino
Scroll down to the packet list and change one of 15auxin “canin” to use as you VSS input port. I used canin[5] as canin 0-4 is already been used fuel fuel, R signal ,L signal, Oil press, P brakes
Find:
fullStatus[51] = lowByte(current status.canin[5];
fullStatus[52] = highByte(current status.canin[5
Change it to:
fullStatus[51] = lowByte(current status.vss);
fullStatus[52] = highByte(current status.vss);
Save file and
save a copy of your project & tune first.
then reflash firmware to Speeduino.
In realdash: ecu specifics
Choose
(Speeduino: auxin5 ) for you VSS input
That’s it speed should now work on serial3
