Title: Fuel economy poll ST1300s
Post by: Sim on March 11, 2012, 05:49:44 PM
OK this for me is interesting. My trip computer (->average fuel consumption) moves very-very slowly.   :crazy I think back to my recent trip to SA from TAS and back which was over 4000km and the best the average got up to was 17.4 km/l (with PLENTY of highway mode). This seems pretty strange as i also commute every day and it slowly-slowly drops (now 17.2 km/l). Does anyone know how the average is calculated on the ST1300 trip computer?  :think1

The computer is probably using the instataneous fuel usage/min and Ks per min to work out the Ks per litre. You could always do as I do, and use the old paper record system (spread sheet actually)

If you want, I can post my spread sheet, all you havw to do is put in your distace traveled, the date and the cost of the fuel. The spread sheet will give you average cost, fuel usage, distance traveled, MPG (US and Imperial), Ks/L, L/100 Ks, Ks/$ and expected range from full tank and to the reserve indication

It'd quite possible your getting an average fuel consumption based on total fuel used over total distance travelled.
I get this on my Territory but I can also get a current usage figure which varies by the second or more (theres other info as well but not relevent to this). The car trip computer can all be reset to zero, not sure if you can do that on the 1300 as I have the 1100.

Average 18.67 kls/lt (43.88 mpg),  :thumb  roughly 60% 2up,   :-++ 

 Best 22.18 kls/lt (52.13 mpg),  :thumbsup Worst 15.59 kls/lt (36.64 mpg)  :'(
 These figures are over 18 fills during 5965 klm.  :hatwave

If it is like my car one, you might be able to reset the distance over which the average is calculated.  In the car I have two trip meters, one can be used for the current fuel tank, the other for longer term.  There may be a procedure in the ST13 to reset the base starting point over which the average fuel consumption figure is calculated.  Just resetting the distance travelled on the current tank of fuel may not be enough to reset the average fuel consumption strating point.  It is not surprising that the average fuel consumption does not change very quickly the longer you have travelled, as the average for a current tank of fuel will not affect the average over 4000kms that much.

I have also read that once the ST13 is in distance to empty mode, don't trust it if you stop the bike than restart. For some reason it resets the countdown so that it is inaccurate.

This has been said before (hasn't everything?) but when mine goes to "flashing" mode I reset the trip meter to 0 and refill before 85 ks on a trip or 70 around town (but been known to quit at 65)   :(

16 for me  :'(
90% is stop-start traffic :cuss and I accelerate hard up to the speed limit most times just for the fun of it :grin (at 5000 rpm the front wheel starts to lift :eek )
The other 10% is 2up :)
All this makes the beaST thirsty but fun :grin still not bad though :thumb

On the slab (the rare times I'm out of traffic) the readout says I'm getting anywhere from 22 to 31 kpl :thumbs
So to fix it up I'm :think1 I just have to do more Hwy riding and stop accelerating so hard all the time

13.5 on average for me, you get that with a 130 +/- speed limit  :hatwave and at $1.80 - $2.20/litre on the Stuart that hurts :cuss :cuss
