Honda was sued over speedos and odos reading high.
Rather than put up a fight, they gave everyone 5% longer warranties on mileage. ( Insight Hybrid )

My 2005 FEH gives me EV at 39.9 MPH and under ( actual ) which looks like 42 MPH.

 

Your '05 FWD FEH is the same as my '05 FWD FEH John.
They are both the most efficient SUV on the planet. At 41mph the ICE will kick-in according to the speedometer. If your FEH waits till 42mph you have a special FEH like Willard dreams of. For years my '05 FEH will start the ICE at 41mph on any downhill so I keep it just under that to stay in EV with the brake in "D" or "L" for regen.

The '09 FEH does the same and restarts at 41mph, but 41mph is 41mph and not 39mph reading 41mph like my '05. You and Willard can now start a new website called Greenhijacked.com and fight over how much alcohol you add to your gas! Happy New Year!

As the self appointed Grand PooBah of this thread I request that it stay on topic and not be hijacked by petty bickering over the E word.

Failure to comply with the ^^above^^ MAY result in a flock of loose bowled canadian geese pooping on your FEH.

...Thank you

 

Just completed my 9th Tank on my '09 FEH and here are the best numbers yet. The Nav Sys had a Tank reading average of 55.6mpg which was 3.05% higher than E10 pumped of 13.453 gallons. This was on a 718.9 mile tank which gave me a 53.437mpg average using pumped gas calculations. My weather averaged 60 - 80F degrees with 35 - 60F today. The wind was bad 50% of the time but this new RFS technique is still awesome in city driving.

Here is my list of pumped gas VS the Nav Sys readings to date for only the '09 models to compare:

9/2/08 46.659 Pumped / 46.4 Nav = -.5%
9/18/08 45.86 Pumped / 47.0 Nav = 2.5%
10/4/08 45.173 Pumped / 47.8 Nav = 5.8%
10/25/08 46.04 Pumped / 47.8 Nav = 3.9%
11/14/08 48.06 Pumped / 50.0 Nav = 4.0%
12/4/08 48.815 Pumped / 51.8 Nav = 6.2%
12/18/08 51.80 Pumped / 54.1 Nav = 4.45%
1/22/09 53.437 Pumped / 55.6 Nav = 3.01%

This brings my total miles now to 6078.9 on my '09 FEH with 129.379 gallons burned from start-up at the Factory. This new tank puts my Lifetime MPG at 46.985mpg. As far as the Nav Sys Tank Average display, the 8 percentages figures above for me added to 30.36%, divided by 8 tanks = 3.795%. So for me, the Nav Sys continues to read ~4% higher MPG than pumped gas. Notice I'm increasing the Nav sys mileage at a steady pace but pumped gas goes up and down. There is a pattern with the Tank fills being higher and lower with the percentages the Nav sys being off.

On this Tank before fill-up, I had 13 MTE left with 718.9 miles on the trip OD. This is the forth time my MTE read a maximum of 699 Miles To Empty after fill-up, so again, the '09 will never exceed that number like prior FEH/MMH models can.

Update on the SGII Tank percentage adjustments:

Speed is adjusted to plus 1% which is not enough, but plus 2% is to much. This results in a Tank trip reading on both SGII's I have to 715 miles VS the 718.9 miles on my FEH Trip OD.

One of my SGII's was set at 12.5% (which is getting crazy) and my Tank average came out at 53.8mpg with 13.2 gallons used. The other SGII was set at 12.9% and that tank average was 53.6mpg with 13.3 gallons used. That was pretty close to pumped gas at 53.437mpg with 13.453 gallons pumped.

I changed the 12.5% setting to 13.3% and left the other SGII Tank refill setting at 12.9%. At any rate I'm getting real close to having the right SGII Tank average setting for the '09 FEH. Note, that after a reset of the SGII and the Nav sys Tanks, it takes awhile (miles) for the averages to compare to each other in real numbers.
