Manual forced Auto-Stop

[drktrpr]

There have been alot to times I've been cruising up to a red light when I wished I could force the car to autostop before 20mph.

Has there been a mod to do this (I couldn't find it) or has anyone thought about it?

Don't worry - the fuel is probably shut off as you are coasting to a stop unless the A/C is on. One way to find out is change the display to metric. Even if you don't switch to metric, when the bar indicates 150 mpg, it's probably shut the fuel line.

It has been discussed briefly before. You would likely have to fool the computer. The computer is generally a tollerant fellow, but you want to watch how you do it as you definately don't want him to get ticked off!

Hi Drktrpr:

___From 19 mph and below, you can expect a normal Autostop. It is those types of coasts from a much higher speed like let’s say 50 mph to a stop over ½ mile + when you might consider shutting down the car and simply reboot it but not start it or a very slight brake pedal depression will give you fuel cut. Is that what you were looking for? I turn back the key every once in a while on warmer days but when its cold, our ICE’s loose to much heat so you might consider foregoing Autostop under most any condition when it is the 50’s and below. Any type of regen is a waste if you are running 18 + bars SOC vs. the free coast if you have that choice. Hypermiler’s always take the free coast when ever possible

No one to my knowledge has tried/tested it, but I am pretty sure if you take the speedometer lead into the ECM and, let's say, build a simple circuit that cuts the pulse rate in half, Auto stop will happen at much higher speed. There might be side effects, it may trigger the CEL. But It will also remove the 113 MPH fuel cut.

(Jumping slightly off tangent onto a pet peeve.)
Honda could have put in an button which, if certain conditions are met, would do autostop. It would save gas on long delecerations and let you coast down long hills with the motor off. They did not because there is a general phobia against adding any controls that deal actually driving the car. Buttons for windows, mirrors, seats, etc.etc, but no trigger or paddle that lets you control the IMA seperately from the gas engine. So they put a computer in charge and let it guess what to do based on it's limited inputs. And we have to put up with it that 5-10% when it guesses wrong.
