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?
Second too this do the VSS, Tacho and Water Temp under Engine/ECU Inputs relate directly to the standard list of CANBUS variables in an ECU OBD data set?
I do not know, as we do not have Speeduino in our test devices. As far as I know Speeduino connection type has not worked for years and users have made custom solutions to read RealDash CAN data instread. Hopefully you can find answers from Speeduino community.
