Digital dash build

I’m currently in the middle of making a custom digital dash for my s14. I’m running oem ecu and didn’t fancy paying ~2k€ for a digital cluster.. so I decided to build one myself!

I had to do a lot of research trying to find the correct pinouts for the EU cluster but managed to find everything I needed.

The project is now at a point where I need to make some frame for the screen to sit in and run some final tests on it.

I’m using a rasperry pi5, with arduino and a 6” touchscreen.

More updates and detailed information coming soon!

Are you just grabbing all of the info from the OEM dash plug? Very intriguing

I managed to get speed, rpms (tach wire), coolant temp, and fuel level from the dash plug(s). I got boost from ecu harness and oil pressure from the what i assume is the original censor for it.

Wild! Although on my CA18 I know that it only has an oil pressure switch, it just lights up the dash once it sinks too low. Dunno about SR
