.....When switching to econo mode I notice an increase in engine speed, appx 100-150 rpm. When exiting econo mode there is a decrease in rpm's. It is very subtle, and more noticeable at low rpm's, say 1500 to 2000. You have to hold the switch for a second after the econo mode indicator goes off, then release it. Just wondering if this is normal?
-
I think it's normal because the Eco mapping will probably lean the mixture, thus increasing the temperature inside the cylinder and most probably generating a slight RPM increase.
I seem to have noticed it, but I'm not using ECO for a long time now.... probably (and perhaps unconsciously...) right because of the consequent temperature increase that could create damages in the long run.
I know it's not the case, but you never know!

....That sounds right, I have gotten up to 48.3 mpg on long trips with the econo mode engaged, but I didn't buy the C-14 for the fuel mileage. I bought it for the Smile mileage.....Gotta Luv It.. ;D ;D 8)

Yes, it is normal

My econo mode on my '08 has the exact opposite reaction. If I have any abrupt changes in RPMs I end up with an ear splitting headache and a ringing in my ears. Borderline concusion once, she likes both wheels on the ground at all time 8)

I hate change....

yeah but it keeps things interesting, without change life would be mundane dull and boring as ...............

I don't see your point.. ;)

Go "Commando", the ultimate econo mode ;)

:yikes: Just when it was getting interesting, the thread was derailed...

Based on my experience with these things, derailment usually occurs after whatever information is requested is received. Derailment shouldn't stop someone from posting information the OP requested. In looking back at the post trail, it seems that the OP got the answer he requested by about post 5ish or so, after which derailment started. Of course, this is purely subjective.

Back on topic, one wonders why the idle map would be any different in eco mode.
-
Long answer:The "idle map" is just he main idle screw. You should have that set to something like 1100-1250 when not in ECO mode. Then when ECO mode is activated, it leans out the a/f mixture. Which in turn causes the engine to idle at a slightly higher RPM.
Short answer: There is no such thing as an "Idle Map" on a C14. So move along. Nothing to see here. ;D
Short answer #2: It's all magic! :P

I think what you are trying to say is that Eco mode leans out the entire map by a single factor. (Why is the idle speed constant after it warms up, when you switch from Eco mode to regular and back?)

I have the same result on my 2012 connie .

When the bike is cold (first started), like most bike engines, it will be prone to dying. If the idle is set too low or you do not wait a minute or two and take off but without enough throttle, it can and will die and I don't find that to be terribly alarming. If there is too much play in the throttle cable, this can amplify the problem, since a twist to give gas might not be quite enough. If you ALSO use ECO mode (which I don't bother with) that will tend to make the idle even less strong, even if the RPM is a bit higher, because the bike is then cold AND even leaner than normal.
I will admit that my 2011 has never died when leaving after cold started, but I almost always start the bike and let it run a minute or two before leaving. It is part of my routine- I am not finished preparing to leave before I start the bike. I will usually start it, and then put on my helmet, plug in my earphones, and put on my gloves and set the GPS/music options, and then leave. I consider this a "best practice". It is "better" for most engines to let the oil get a little up to temp and flowing through everything before calling for power.
A few times I have killed the engine, especially when the bike was new and I was slow manuvering, and I had too much play in the throttle. Once I got more used to the bike, and also removed the throttle play, it was never an issue again.

This has been discussed several times before, and from what I recall, the consensus was that when the bike is placed into ECO mode, the computer will raise the idle speed until the bike has reached reasonable running temp and then it is reduced back to normal levels. This is done as a precaution to prevent the engine from dying too easily when coping with a leaner mixer AND being cold.

This is not the case with my bike. After I've riden for a while and the bike is fully warmed up, I can come to a stop and toggle the ECO mode on & off. The rpm is higher when the ECO mode is on vs. off.

Sorry, I missed that memo. But I guess that makes sense.
Given that, I wonder if it's better just to immediately place it in eco mode, and accept the higher idle vs. a low cold idle with a richer mixture. I've always let it warm up first then put it in eco mode.

Guys, isn't it because te ECO removes power and the engine has to work a little more to mantain the same performance? I always use ECO anywere I go and, at my speed, until now, it's alright.
