To anyone who just recently bought a HAH (after April) or has gotten the software update:

PLEASE PLEASE PLEASE tell us you mileage and put it in the DB! The new software supposedly gains you some reasonably significant increase in MPG. We need to know what the real results are, and what it did to get them!

Thanks!

 

Is it backwards compatible?

 

I couldn'tfigure out how to add my car to the database...I have a post April model...

 

You should be able to go into the "compare" section- the database- and under your name on the left margin should be a link to manage or add your cars.

 

so... anybody got a newer 2006 model? Care to tell us how your FE looks?

 

Those of us with the early '06s should be getting a notice from Honda soon to get our ECMs reprogrammed. Then we'll know what difference there is.

 

you're the group I'm really interestd in- you can do the before/after determination.

 

I purchased my 2006 HAH on April 27, 2006. According to the door panel date, it was assembled in Japan in late November 2005. I have no information if it has the updated programming or not.

My car is included on the GreenHybrid database a Casper Desert Mist.

So far I have been greatly pleased with the mileage, 24 to 33 in town and 34 to 42 on the highway. Lifetime 32.1 mpg. Somewhat better than the 2006 epa#s but about what I expected as I tend to get slightly better than epa on every vehicle I drive - except that with my work machines, pickup (Chevy) and SUV (Ford Expedition), I get less because of lots of off road miles.

In my experience the highway mileage is more affected by "external effects" like wind conditions, portion of city driving encountered, etc. on a tank than by "internal effects" like A/C, windows. That is except for one thing - I use the cruse a lot. I have noted, (but cannot back up with data), that I get 2-3 mpg better than my wife who does not like to use cruise.


The vehicle is a thrill to drive and ride in. Only one mechanical problem so far, the check fuel cap indicator came on during week two and baffled the service guys until they replaced the cap. Now all is fine.

 

According to Honda, the updated programming was only implemented on the assembly line in April 2006 so it is almost certain that your car does not have it. Not to worry though, the update should be available for free by the end of this month.

 

I went by the local Honda dealer yesterday and asked about the update, they did not have any information. Hopefully once we get contacted by Honda about the update the dealerships will have the update.
