Hello all,
So I’m looking to use the serial3 aspect of the Speeduino so that I can input my fuel level into the Speeduino and then this will allow Realdash to grab this input.
However, in the list of inputs for the ECU there is things like RD-ONE Spareport bit 0-7, Dashbox, Speeduino Auxin-gauge 0-15 and some others.
I’d like to know which of the Realdash terms relates to which Speeduino input from Serial3 please?
Ta,
Mike
When selecting input, use word ‘Speeduino’ as a filter.
Also, while connected you can go to ‘Settings->Application->Debug->Debug Data View’ to see in real time what values are coming in from your ECU.
I’m still in the development stage and planning things out so don’t have the ECU yet. Hence, was just trying to find out how the Realdash list of available data points lines up with the Speeduino serial3 data points.
I was thinking these data points would be a bit easier to find in both the Speeduino and the Realdash.
Speeduino custom inputs will only appear into the lists once you make a connection to the ECU. This is due that available custom inputs depend on firmware version.
Righto, so I need to purchase the Speeduino and figure out the serial 3 connection to the Speeduino for Realdash to populate the serial 3 inputs? Correct?
Yes.
You can make a Speeduino connection without ECU (use TCP/IP connection type) and when RealDash attempts to connect for the first time, the default Speeduino inputs will appear. The default inputs may not contain all inputs, or may contain inputs that will not come from your ECU, but should be something for you to get started.
I am using speeduino Aux 0 and Aux 1 as local auxiliary input channels to serial 3 and Realdash. In the RD ECU specific inputs list are these Can1 and Can 2?
I worked it out and yes they are CAN1 and CAN2. Obviously if using a 0-10 bar sensor the scaling needs adjusting in RD but all good now.
As time marches on the Dropbear ECU version of Speeduino seems a nicer option and it has inbuilt CANBUS. Looking at the Speeduino Wiki I would need to use TunerStudio to make Fuel level and Oil Pressure Aux 0 and Aux 1 as these parameters are not part of the standard CANBUS data list posted in the Speeduino Wiki but rather require the use of mode 22 for auxillary data.
I’m assuming that in Realdash ECU specific inputs Speeduino: AuxIn_Gauge 0 is using CANBUS mode 22 comms and directy relates to the auxillary CANBUS data list of the Dropbear ECU?
