My FC Getting Better With Low RPM

<< < (20/37) > >>

Unfortunately, I haven't been able to get it to work... It works great in the Jazz and you can read throttle position, battery voltage, engine load, FC, etc... Sigh, too bad for us. I have tried scrolling through many different settings to no avail. Perhaps a guru provide some advice?

I have much to learn! ;D

Err, I don't think I'm "pro". There are several factors that weigh things in my favour:
- long continuous drive of 37km each way minimises warm up hit on FC
- having 65% ~ 75% highway commute
- the fact that I don't mind going a little slower

There are the lousy FC tanks too:
- 2 13.75km/L tanks
- 1 14.66km/L tank
- 1 14.74km/L tank

The guys from CleanMPG would probably be pulling over 25km/L if they had my car and route... I have no idea how that do that... Out of this world.

So maintaining around 2k for acceleration is best. After that cruise at around 80-85 should be ok. Anymore higher and the higher constant rpm and large wind resistance is terrible for FC.

While it is true that having a wide open throttle minimises throttle loss, there are other factors to consider. Throttle and RPM's are not necessarily directly related. Engine load can influence throttle position.

I am guilty of accelerating slowly. My aim to to spend as much time in the maximum gear ratio which loads the engine as much as possible at a given RPM. After a short blip to 1500rpm, I ease up on the throttle to get it down to 1200rpm. Wait for speed to hit 60km/hr and then there is a sort of ratio lock-up and I can accelerate the car from that point onwards in "top" gear.

If only we had a 5-MT Latio! More tricks to play with.

SoL:
Yeah, a manual Latio for FAS!  ::)

Joking, fas in singapore can die. The traffic here is terrible, especially in rush hour. My heart pains everytime I go into CBD, thinking of all the fuel wasted/

fri13th:
Hi everyone! today fuel tank lights went up and pump in 37litres of petrol milaege 664km :out:
Thats about 18km/l :yehyeh: really still getting better with each tank! :w00t: wondering when my good Fc will reach its limit :bleh: I think only time will tell ::)
