Re: Fuel Injector shut-off while Coasting
Quote:
my car is an auto with five gears. A first on the civic. I do notice that it likes to hold the gear while deccelerating. It'll get down to about 800 rpms before down shifting when coasting. So are you guys saying that it is more likely that OBD1 cars do this and not so much newer ones? I know metro said his was OBDII. Is there a way to find this out without having to call a honda engineer? |

but... i believe only cars with *manual* transmissions do it. if the injectors shut down in an automatic, there's nothing to keep the engine turning (no direct connection to the wheels). the engine will stop when the fuel stops. |

Lock-up solenoid?
No clue. The inner workings of an auto tranny are still a mystery to me. I could tell you all about genes, DNA, and complex molecular reactions, but auto trannies .... it's like pandora's box
I doubt there is a service manual I could get my hands on at this point in time since the car is so new. I suppose I could bombard Honda with e-mails, but I have a feeling they'd be reluctant to share the specifics. So if the injectors don't shut off completely, do you think that the fuel input would be reduced since there is no load (however I'm not sure if engine braking would be considered a load by the ECU) on the engine as opposed to being at idle? |

I've noticed something
Via the ScanGauge, I noticed something. I figured that coasting in Drive would be more efficient because of the FI cutoff, but that doesn't seem to be the case. When forced to idle in Neutral and coast, the FE goes up considerably, even at slower speeds. So anymore, I just pop it into N and coast just about anywhere possible, and the results have yielded at least a 1-2 mpg increase, not including more FE with engine-off coasting.
Something to consider... |
