HI,

I have the CT for about a week. Still didnt get a chance to get on the highway yet. However, I did feel it whenever the ECO mode kick in. is it normal? I guess it should be since there are cylinders shut down when the ECO mode is activated. Just wanna to know whether others also feel it. BTW, it is really a smooth and quiet car. Love it so much

Welcome to the forum and congratulations on your acquisition. I bought mine 1 August and have no regrets.

Sounds like typical behavior on the ECO mode for a sixth-sense person like me and apparently you too

 

[chefmark]

I think I can feel it but I been told you should not feel the shift to ECO mode. The one thing that I have notice is the Gas pedal seems to be very touchy. I noticed if I move it ever so slightly you can feel what feels like a shift. I can tell this cause when I have the cruse control on I do not get any shifty feelings.

I too think it can be felt. Not quite as undetectable as Honda would have us believe.
I don't find it intrusive or bothersome and the light going on and off doesn't bother me but I do understand that it could be bothersome to some.
Kind of pointless when you think of it and certainly wouldn't mind if it weren't there at all. (light)
I can see that biting the dust in the future.
As far as cylinder deactivation: I like it. I still don't really understand how it can run well on only one back of cylinders but apparently it can.
I like anything that will extend my miles per gallon.

I do believe that 'reactivating' those 'deactivated' cylinders (on acceleration) is much more noticeable and causes a slight pause for lack of a better term.

Hi all, thanks for the information. It didnt bother me either. I just wanna to know whether others also feel it too.
It also seems to me that the CT downshift very quick and very responsive.!

If you don't feel ECO mode go to the doctor quick, for you must have lost all sensitivity and don’t have a clue. OK, you will and should feel the shift changes due to cylinder changes and that’s normal. It took us awhile to get use to the slight surge on/off but now don’t notice it unless we see the ECO light come on and expect an change. That’s what we get when go “green.” Glad to have you here and let me tell you…this is a great auto.

I want to adjust how it comes on and off, anybody know anything about tuning these cars?

Thanks,

Ryan

Anyone notice that the eco mode takes a few miles to "warm up" or whatever before it kicks in? I don't know if it is just because its so cold out and it waits for the engine to warm up, or if that is just the way it is, that it takes a few miles. Also, why does the eco mode go off, or not kick in when stopped at a light for instance, or at idle?

Ok, I was wrong on this one, it is the ECO mode kicking in that cause the slight jerk in the car. Of course there is always a jerk in the car according to my wife.

Yes, I did notice that. I guess the engine first has to come up to Optimal Temp.

I haven't noticed the "warm up" period. But I've heard the first few miles after starting a cold engine are the most inefficient so maybe Honda is just being honest there. Similar things can be said about an idle car, i.e. that is the most inefficient state of the car (gas being spent but no work being done).

I was told by two people at the dealeship that the "ECO" light and the cylinder deactivation are two different things. They are not tied together. The "ECO" light operates off manifold pressure and the cylinders are deactivated by the computer. They probably do operated at the same time but are not dependant on each other. Has anybody heard something like this?

The system seems a little more complex than that in that the ECO light won't come on until the engine is fully warmed. During warmup I can't believe that vacuum changes.
To my mind, the light and the actual deactivation/reactivation would have to be linked.

Just a guess.

If there is less manifold pressure, then the engine would be working less (not under acceleration) there for the variable cylinders would turn off then wouldnt they?

I love dealer mumbo jumbo...

Next, the car accelerates not due to you pressing the accelerator, but as the result of the engine crank pushing the transmission, has nothing to do with you accelerating...

 

[gmcc]

I thought they wer tied together also. The salesman told me they were not. I usually don't believe salesmen so I asked the service mgr the other day. they both said thye are not connected.
Interesting.

Absolutely, but what I meant was that the vacuum would not be the only influence on the ECO mode.
To my mind it would have to be computer linked too.

......and when the engine is cold there is no cylinder deactivation -- until engine is fully warmed.

[veasnalong]

talk to the dealer about ECO, due to high RPM to help the car warm up quicker when engine is cold that is why ECO not activate just like you pushing on gas paddle.

 

[jmj]

I think I know what the confusion is about...

On some of the Hybrids like the Civic Hybrid, there is a ECO BUTTON that you could activate and the car basically will have super slow acceleration to use the least amount of fuel possible.

 

[Ghosthawk]

ECO mode on my daughters Civic changes shift points and cycles the a/c compressor less often among other things to reduce engine drag and save fuel. (at least according the online manual) Honestly when I've driven the car I can barely tell the difference.

 

[ivanoski]

I never feel it
