Part of the plan is to keep the inside looking as original as possible to it retains its 70’s charm. I want to keep the seats, the original gauges, including the clock.
On top of that I still want to be able to see boost pressure, AFR, any error the ecu can provide over and above the engine light which most people do with an led.
The ECU can produce errors such as Oil Level Low, Oil Pressure Low, Engine Light.
I also want to display oil temperature.
Enter - the tiniest OLED colour screen ever in the world ever. It’s really small!
Did I mention it was Small? It is just under 1” and will hide in the upper half of the tach about where the words “x1000” are printed.
The ECU generates each error by pulling the relevant pin to ground.
Each pin will be connected to an Arduino which will load the relevant image from an SD card and display it on the screen if there is a problem.
There will be an oil temperature sensor connected to it and the oil temperature will be displayed until it reaches operating temperature at which point it will be replaced with a boost gauge on one side and an AFR reading on the other side.
The oil temperature will reappear if it gets too hot.
I will cover off how I am doing the boost gauge and AFR when I buy the parts and start adding that into the system.
This is the screen:
Did I mention it’s little?
I have a video of testing the ecu errors, just displayed as text at the moment.
You will have to use your imagination though as I can load a video with Tapatalk and I can’t be arsed to put it on YouTube and add a link.
