Anyone Ever Build a Custom Selector Switch Panel? (LCD, TFT, etc?)

[Getslideways]

I was wondering if anyone knew how the input and outputs from the remote position switch selector worked based on each position? (the box where you choose what current tune position you would like to run)

I was wondering if anyone had built a custom tune selector interface to communicate with the PCM chip? or that used information from the selector switch to trigger a secondary custom programed readout.

(so essentially something that replaces the selector box entirely, or just piggy backs off it to provide an additional visual representation)

It could be fun to make a little visual representation for each tune position on a 2x16 LCD or TFT display instead of trying to remember what each number correlates too. I just wasn't sure if anyone had made something like this for themselves, or knew of how the communication between the selector box and the chip worked so that the right outputs for each position could be programmed.

It could be a much more complicated communication system in which case maybe this idea may not be worth pursuing, but figured I would see if anyone had dabbled with such an idea before or had any knowledge to share on the subject.

Just two fun potential examples for a 65hp tow tune animation and a 65hp street tune animation on a 2x16 lcd i whipped up real quick:
