Hi,
I have a bar graph, and also a gauge on an alternate page, to display boost.
Input channel set as ecu.boost. The ECU is an EMU Black, on the appropriate BUS and displaying all other requested ECU data without issue.
Do I need to make a table in the ADU project tree, as with AFR, to display boost or should it be working with this simple selection, like say oil or fuel pressure do?
Thank you 
The ecu.xxx channels are universal channels.
They are there to have common channels for the ECU data.
It doesn’t matter what ECU you are using or how you input the data, engine speed is always in the ecu.rpm channel.
That said, not every ecu.xxx channel will be populated.
It depends on what this specific ECU is sending over to the display.
EMU Black doesn’t have a dedicated boost channel, so it’s not populated.
You have to use ecu.map in this case.
You can create a number or a table to convert MAP to boost pressure.
Cool, just assumed the EMU would have one, no worries, my mistake.
Will get a table together, thank you.
Does this look vaguely right or can you correct me? Thanks
100 kPa would be zero boost.
200 kPa would be 1 bar of boost.
Boost pressure is defined as pressure above atmospheric.
Ah that makes sense, my mistake I was incorrectly working from 0-100 as up to atmospheric, which makes no sense now I think about it.
I will revise now, is it otherwise correct layout wise?
I don’t tune engines or do the setup side of things generally, hence the lack of knowledge, thank you.
Does this look like decent resolution for a 2 bar gauge? Not 100% exact but enough to spot a fault and reference the typical rough value for familiarity.
Now you changed two things at the same time.
With this setup, a manifold absolute pressure of 200 kPa would be reported as zero boost, which is incorrect.
You are overthinking it.
100 kPa = 0 bar of boost
500 kPa = 4 bar of boost
Everything between will be scaled.
Awesome, thank you very much, over thinking is a common problem here 
Thanks for your time
