Alternator switch

Your first sentence sounds good to me: alternator will be ON every time the car is down a slope or going to stop.

However, it will be on always on accelerating.

The second sentence I do not understand: turn off the power to the fuel injectors with the same switch.... while coasting .... hmmm ok, that makes maximum fuel saving. I think this is already programmed so in modern diesels, I donīt know about gasoline engines.

I think yr ideas are good because they are logical and simple. Good for starting. However, I would like to have more power when climbing, and more fuel yield when traveling, turning off the alternator, when possible. Arduino can help.
