Hey everyone, long time lurker, first time poster.
I'm putting together a car computer and one of the functions I need it to measure is the pressure of the turbo boost. My uneducated idea is that I run a tube from the vacuum hoses into the car, connect it with a pressure sensor and use an Arduino set up to translate the pressure into something a car computer will understand. The computer then displays the boost reading (probably in numbers as that's easier).
Some pre-answers... firstly, the car doesn't currently have a boost gauge, otherwise I'd just get the info from the ECU. Secondly, the boost, in theory could be anywhere between -30 to +30 psi.I'm happy (and would prefer) the resultant reading to be in psi.
I feel confident that I can blunder through this project, but I have very limited electronics skills and haven't yet learned the programming side, but I keep hearing that Arduino is easy.
Any advice would be fantastic, especially on the hardware side (sensor and Arduino set up especially).
Also, to reiterate (so mods don't move this) the key queries I have revolve around the sensor that I plug the tube from the vacuum tube into. I'm not really sure which one to get or how to read from it.
