My temp gauge is doing some funny stuff. I want to be able to see the data coming directly from the sensors while driving, so I can see how hot the car is getting and under what circumstances. According to the gauge, the operating temp is ~80 degrees and the fans come on at ~90, so it's definitely not accurate - I'm just hoping the sensors are better.
So, as far as I know you can get readers which basically show you the data from the ECU as requested. However I want to be able to mount a small screen on my dash that can give me an overview of all the data at once in realtime. I want to be able to see the current speed, RPM, engine temp, and anything else that might be interesting to see. It'd also be cool if I could record this data over time and make some cool graphs.
I'm a software developer by trade, so I have no problem sourcing the hardware and writing some computer code to do this. Just wondering if maybe someone has hooked an Arduino or Raspberry Pi or similar machine up to an Alfa before? And if it's possible, how difficult is it and what are the limitations? I assume I have to buy something to read stuff from the ECU (ELM327) and then hook into that?
On another note, after 3-4 months of ownership, I've decided these cars are easily the best way to spend a bunch of money (in a good way!). I still can't get over the rumbling sound it makes at low rpm, as well as the screaming sound it makes at 6000
