Fuel Cutoff?
SoL:
Hey aerosignal, so disregarding the human safety aspect, its not harmful to the car if I coast on Neutral with my engine on?
As in, it won't spoil the transmission? Latio is not flat-towable mah.

Er that one I don't really know. Effect to car, coasting at neutral is related to the transmission, not the engine.
At neutral, you have to burn gas because your engine is no longer driven by your wheels.
With engine brake, you may slow down abit. However, I find that on ben shears, I can sustain 80 kph coming down without steppping on accelerator at all. This means that I am burning 0 fuel when coming down the bridge.
I think you got the neutral coasting idea from hypermilling sites where they do at times coast at neutral. However, most of these people drive hybrids and it works very well for U.S. roads where they have long stretches of roads with gentle incline. In our case, the slopes are usually steep and if you go to neutral, you will accelerate down the slope so much you have to use your brakes to slow down (traffic). As mentioned before, everytime you step on brakes, the energy you created goes into thin air, wasted as heat.
For what it's worth, I wouldn't try coasting at neutral myself because I don't think I can save more that way. Just accelerate less so you brake less.

I always practice brake less. Onli no choice den i brake, normally will try my best not to press any brakes.
You can also try looking far, the furthest traffic condition or the next traffic light, den decide to press acc or dont press anithing, until u are close enuff to a stop den press brake.
When approaching a red light, I will aim for the shortest line and release acc and not braking onli when close, coz incase it turns green I still have some inertia with mi, so can move off much easier
Just 2 cents

Basically, when you don't step on accelerator when car is moving, the fuel injectors cut off (no fuel at all). When the vehicle slow down to a preset speed 20 kph or something like that the fuel injectors turn back on again to keep the engine running.

True, When I see red light far ahead and no car behind me, I just left go acc. The car will slow down to ~20kmj then there is a sudden slight rush forward guess the car decide to pump some oil to engin at that time. I am driving a CVT so the rush is not due to gear change. Did not change to N
