2010 ECON Mode

[Mister Tee]

There are several factors that affect mileage such as heat, elevation, gasoline blend, etc... Economy is more affected by the heat on my C14 than any other vehicle I've owned, bike or car.  But also gasoline can play a difference.  If you go on a long cross country trips, you're bound to get a mix of gasolines with and without ethanol.  I find ethanol blends, which are prevalent in California, yield about 10% less mileage than normal gasoline.

If you go on a long cross country trips, you're bound to get a mix of gasolines with and without ethanol.  I find ethanol blends, which are prevalent in California, yield about 10% less mileage than normal gasoline.

Ethanol in gas is also very prevalent in Oregon and Washington (actually required by State Law).  Ethanol is higher octane than gasoline but contains 30 percent less energy, so a 10 percent ethanol blend will result in a net energy loss of 3 percent.  We have a few stations in the area that sell non-ethanol premium and I try to use non-ethanol gas whenever I can but I haven't seen much of an improvement in gas mileage even when I use the non-ethanol.

During my trip I stopped at several stations in South Dakota and Montana that were adding 10 percent ethanol to 87 octane gas and calling it 89 octane super unleaded...and charging a dime less per gallon for the "super unleaded".  Those stations usually did not sell premium gas.

make no mistake , you bought a comfortable(after everyone installs risers)  zx-14 with hard bags.
 self canceling turn signals and maybe a cruise control is all i would like to see but i can add that myself.

My 2010 C14 is used primarily for touring and with the price of gas today, I am wondering if the ECON mode has even more potential for fuel economy...plus I have a PCIII that is a left over from my 08 model and would like to get some use out of it.  There are fuel maps available for the non-ECON mode but I haven't seen any maps for the ECON mode nor I have seen any information on what kind of fuel ratios the ECON mode is attempting to achieve.

Does anyone have any data that I could use to build a fuel map to optimize the ECON mode?

I contacted Fuelmoto with a similar question if they do a map for my 2011, the answer came back that as yet they hadn't developed maps for my model as they have not received a 10/11 model for map development, but they have for the earlier models.

A somewhat related question....why do the revs bump up when you switch on ECO mode?

Is it because the engine leans out? If so....is it my imagination that the bikes feels like it has more go down low?

I would have to say that I am not much on the MPG thing as some of you guys are, but to save $350 is a very nice savings! you can put all that savings back into the bike. very nice

I don't know why the revs bump up but they only do that when the engine is cold.  If you wait about 30 seconds (which you really should do anyway on a cold start) you will find that after the rpm's decrease to their hot idle setting, switching to eco mode doesn't change them.

I can't really tell much of a difference either way, power wise.  Some say it smooths out the low end throttle transitions.

Being cold may make the bump larger, but on my bike it definitely bumps up a notch when warm or hot.

Only way to really know I guess would be to get a bike on a Dyno....oh well.

When I use ECON full time on highway and back roads with little slow downs I get around 48-50MPG average compared to 38-41 without it. From my usage i would say it works.

My bike jumps the idle 500 rpm in ECO mode. Tech rep says that shouldn't be,
seems like some bikes do  and some don't. Mine has done it since it was new,
still doing it 23k miles later.

Mine did that to.  All I did was adjust the idle adjustment set screw that is located on the lower left side of the bike, just in front of the gear lever.  Just bring it down a tad.  I set the idle to about 1100 rpm.  The only time my bike does it now is when it is cold, so when I start the bike, I leave it out of ECON mode until the bike warms up a couple of bars.  This has worked perfectly for me.

The ECO mode should make it idle at a higher RPM since the gas is being leaned out to get that 10-15% more.

Mine does the customary idle increase in ECO mode when cold but once the bike warms up the idle is back to normal. Go figure...
