Ok.

The way i drive is as following: when i see a traffic jam or slow trafic or a red light. I put the car in nutral and let it coast with an ideling engine.

When i need a constant speed. I use the highest gear possible.

What happens if i coast more times. Like when i aim driving at slow speeds. 50km/h and 70km/h.

Wil i benefit if i p&g (pulse and glide) at lower speeds?

What more mods could i do?
Where do i find info of an switch for cutting the fuel to the engine so it will die. With the key still in the 'on' position?
