Hello,
One of the things that can be displayed on the instrument cluster is the air to fuel ratio. What's the point of that?
If I had a carburettor and wanted to experiment with its tuning, then I guess the air to fuel ratio would be a good indicator of what I was doing. However, in a fuel injected engine this ratio is automatically set by the ECU and cannot be changed or influenced by external means in any way. So, what's it to me whether the air/fuel mixture is lean or rich, considering that I can't do anything about it anyway? What am I supposed to do with this information?
Is it just a beautiful but useless gimmick, or does it really serve some practical purpose that I'm missing?
Thank you.
