Breathless Mods?

[TheGoodHummerMan]

Great, while surfing the `net I came across a site that said that running an engine with a computer set for a certain temperature would get REDUCED gas mileage if the temperature range were lowered because the engine would run too rich.

Now what the heck is THAT all about?

If the computer is sending a set amount of gas into the engine based upon an expected temperature range, how would reducing the temperature REDUCE the mileage? I can see where it might be possible (MIGHT) to reprogram the computer to get increased fuel economy, but not how it would hurt just to lower the engine's temperature?

I am getting a headache.
