The difference between 72MPH and 73MPH

vman1313 · August 27th, 2013, 02:05 PM

OK...this is just one of those random (and stupid) thoughts I had while riding my 300 the other day on the Interstate.

So the 300 has a little indicator that shows up when you are riding "nicely" called an Economical Riding Indicator shown by an ECO symbol that pops up by the speedometer. First, I think its a funny little indicator because who in the world should be looking down at this small little icon while riding a motorcycle just so they can make sure they are riding economically?!?!?

Anyway, so I was on the interstate and looked down to check my speed and noticed that ECO symbol on while I am doing 68MPH. Which made me think, how fast can you go and this symbol still show up? So after some tests, the fastest I could travel was 72MPH and at 73MPH it turns off. ((and yes I know, I did what I just said was funny...I stared at the little indicator light to see if I was riding economically

but it WAS for science purposes

))

So whats the difference between 72 and 73 that makes the bike economical at 72 but not at 73?

it shuts off when you go past a certain % of throttle OR past ~8000 RPM, not based on wheel speed, only engine speed/throttle position.

+1 with the +1 CS 72 MPH indicated is the max speed the ECO thingie is displayed, even when going downhill with a tail-wind. Since the ECU runs Alpha-N, GHill762's statement about TPS or RPM being the main variables for the ECO light seem plausible.

I understand an ECO indicator on an F-150. A 300CC vehicle? Not so much. You can ride WOT with this thing everywhere and still get better mileage than a hybrid.

idk about that, that's what I do and I get around 40-45mpg which is comparable/worse than a hybrid

I have gotten 75mpg before though so really if I want to get good gas mileage then it is possible hahaha
