Awesome screen - reminds me of one of those old cashier screens.

An extra tip for those re-creating this gauge.
Incorporate a ambient pressure sensor to have even more precise boost readings in higher altitudes and changing climates.
How to can be found here. I wanted to do the same, but my barometer didnt come in mail till today :D

That's exactly what it came from, funnily enough

Nice stealth! For a simple baro sensor, you can just save the initial pressure reading at power-on before starting the engine (idea courtesy of megasquirt).

#include "SSD1306Ascii.h"

The compiler needs that file (SSD1306Ascii.h). You can download here.

You may as well download SSD1306AsciiAvrI2c.h as well since it's likely you don't have it. Based on the code, once you've fixed that first error, it'll just choke on the second include.

I couldn't quite work out the wiring from the original pictures, so hopefully this picture helps others. Now working perfectly.

I'm planning on doing this paired with a boost control solenoid to swap from my mechanical rig.

And maybe later add a wideband to the same program.

Will post it when done.

Thanks a lot for sharing, this is awesome! I just ordered all parts. No experience with Arduino yet but I'm excited to try this out.
