Advice on disastrous FC

Also, what speed do you drive at in expressway? Traffic jam alot? Idle in CBD alot?
Check this post I wrote long ago: http://forum.thelatioclub.org/index.php?topic=7701.0

thanks.. it was helpful :w00t:

When the light turns green, apply gentle pressure and let the engine rise smoothly to 1500rpm. Then slowly ease back a touch to encourage the CVT to a higher ratio. Once you get down to 1200rpm, keep steady pressure on the pedal and watch the speed climb to 60km/h. Of course, you have to be a little patient. When you reach 60km/h at 1200rpm, you are at max gear ratio, and you can increase pedal pressure *gently* to get up to your desired speed while keeping the highest gear ratio.
This is much easier to do with the A/C off. Takes about 18s to accelerate to 60km/h from a standing start on level ground.
The best way to find out if this technique works better than a high rpm take off is to grab an FL Latio with the built in FC meter. Set a fixed route and test both methods several times with the FC meter set to average mode. It would be great if someone can do this and post the data.
It would also be great if someone could post FC .vs steady state cruise speed with and without A/C, windows up. Then we can find the sweet spot and keep our accelerators pegged at that spot.

was reading up on that refered thread when i saw this post regarding gear ratio on CVT engines. If i'm not wrong, cvt engines should be having infinite amount of gear ratios to give u the comfort in your ride. Letting go of pedal and pressing in again is only an imaginary thing that makes u feel that you are driving a 4at car.
For me, if i need better FC, i will step in harder to attain 80km/h. took me 5-7 secs to reach that. i dun mind spending that one blast of petrol and then cruise rather than to constantly let the engine drink petrol for 16 secs. energy needed to overcome fricitional energy over the extra 9secs can be used to cruise for more distances. :p

Considering latio takes around 11second to get to 100km/h, your 5-7sec to get to 80km/h seems like a very large blast of petrol. I would guess the rpm is about 4k? A lot of petrol is wasted on overcoming frictional energy in the engine.
The key thing is not to care how much petrol your burn, but rather how efficiently you burn the petrol.
I'm not too sure about the CVT part, but I think you're right. I remember CVT does not have fixed ratios like 4AT.

Yeah thats what I read up about CVT also.. no fixed ratios.
Agreed with what you said about efficiently burning your petrol. Never really timed the acceleration but gave a super rough estimate. Maybe later when i drive i go time.... hehe
