The gauge pod is just on a metal backing plate that i made up and is easily removed. Can make a new backing plate easily

Perfect. Might even be worth grabbing a 2.4" or larger to fit that surround fully. How are you with C (language)?

Maybe some of the other guys with more programming experience can chime in.

But maybe a basic pdf saying how to place what where on the screen etc etc

If the tunerpro format is open i'll support that. Having a look at a log file it looks like a header then just the message0 frame with a time stamp. Is there more info on it?

An app my brother is working on to make the display a kind of drag and drop setup. Still early days on that side but the text scripting is just about finalised so if you can wrap your head around the config file format you should be able to create any layout you can think of.

I'll add in firmware update over SD card to make any firmware changes super easy to manage.
