Rolling on neutral from any gear, downhill, etc.

are you guys sure? (serious question)

coz voltage readings of AFM/MAP/O2 are VERY low on idle with injector duty cycles around ~%5.. ie Neutral....

Or is what tinkerbell said above a specific Honda 'feature'?

with that ~1200rpm thing, does it happen around there or below that?

when injectors are shut off - injector pulse width = 0

when injectors firing at idle - injector pulse with > 0

as above,

the cut off rpm is around 1200 to 1500 rpm.

it determined by rpm, tp, and map inputs to the ECU

If you some what, like it being in neutral, use the clutch instead.

Easyer to let go of the clutch rather than put it in gear.

Then you will wear out your throwout bearing prematurely instead.

Hmm since the topic of leaving it in N etc is up I might ask a noob Q.

Some people mentioned that leaving the car in N will result in the car consuming fuel to prevent it from stalling. However other people claim that leaving the clutch in will wear out your throwout bearing prematurely.

Scenario: You sit at the turning lights and the first few cars manage to get the green but u being the unlucky one catches the red again so this means another 3 mins wait at the lights until your turn.

In this case would you pull your handbrake up and leave it in N and wait until the light goes green

or

Keep your foot on the brake, foot depressing the clutch pedal whilst in 1st gear? As we all know that we've been taught to always keep it in first by our instructors.

What's the best thing to do?

I leave mine N handbrake on, I was taught to take corners at 5km by my instructor, do I still do it? No

Put it into N and put my right foot on the brake pedal.

what is the point of using your foot brake instead of the hand brake?

I believe because the brake has more "stopping power" than the handbrake, as the handbrake is meant for keeping your car from rolling, such as on a hill, well, anywhere.
