Try Wira 1.5A with three forward ratios and no lockup clutch smile.gif Have you also driven a Kelisa auto? Ah, you haven't looked around enough LOL...

Cheap car? Don't be so quick to judge. Even current Accords, Camrys etc lockup only on 5th. And not only fast cars have lockup on every gear. Pug 407 and 308's original AL4 gearbox also lockup from 2nd gear onwards, and sometimes even in first. It all boils down to engineering design decisions, not about how fast a car can go. And FYI, Toyota has also started to employ lockup on every gear on some of its new mass produced cars.

If you have the time, read Pg 18 of the following pdf:
http://www.scribd.co...L4-Transmission

Driving smoothly, yes, but not to the point of driving too slow.

Too slow = dragging the car, not taking advantage of forward momentum.

Too fast = higher wind resistance that counters the benefits of forward momentum.

Vroom and brake, sure makan minyak wan loh. Captain Obvious!


accord & camry are cheap car(not in msia though, its affordable in everywhere, since u talk about design we talk global stuff la, what wira, kelisa? you have that in singapore or uk or US?) and compare to merc AMG, they are dirt cheap car.

lol, you're an ahole, lol. yea, lockup clutch and stuff, but,

1. this kind of knowledge wont help ppl save fuel ( wat? you can modify your wira? no right?)
2. yea, this kind of knowledge u can get from google in a second, so, why waste time explaining to ppl in forum in such details?
3. this kind of technical knowledge should be delivered in automotive school, and for ppl who wanna fix/design a gearbox.


by the way, i understand why ppl wont listen to you, its the way of deliver a msg, ppl still hate it even if the msg is correct. Captain obvious? ..l..

even if you got PHD also ppl wont listen to you, lol.

Ya, basically it means to reach top gear as soon as possible. I have only test driven the 2.0 FL once so I can't say with certainty, but I've tested a Peugeot 308T and also read about how there is a lock up clutch on each gear from 2nd gear onwards.

On the 2.0 and 2.0 FL, I'm fairly confident that there is a lockup clutch if not in every gear, then in top gear.

Thanks for sharing.... I once ask SC manager about this phenomena and he asked me to come over to reset the ECU sterb292.gif
Now, I know why... smile_thumbup.gif

Sorry, instead of clutch lockup, im getting brain lockup.

In short, does reseting the ECU help with the lockup clutch?

In a way, it does explain why my Gen2 1.3 was previously fuel guzzling, but is now less fuel guzzling.

It could also explain why my Forte 1.6SX is now fuel guzzling.

Does plugging off the car battery for two or three days... cause the ECU to reset?

If you drive either a 1.6 or 2.0 with a heavy foot, the 2.0 will consume more fuel, period. I'm sorry bro, your explanations are all over the place and full of conjecture.

If you want to save fuel, accelerate gently and not like a jackrabbit, and anticipate stops ahead.

Try to achieve top gear with torque converter lockup as soon as possible, which means no pussyfooting uphill, thinking you're saving fuel when in fact you're dragging the car and not taking advantage of forward momentum. The catch is to spin the engine the least, at max possible speed.

When on a slight decline, feather the throttle, and if speeds are high enough, don't touch the throttle altogether, because when there is enough momentum to keep the car running with no pedal input, the ECU will shut fuel off completely. Already proven in hypermiling circles.

In traffic jams, a 1.6 will burn less fuel at idle compared to a 2.0. Also, when you know the lights will take at least a minute or so to turn green, push the lever to Neutral. Leaving it in D will consume more fuel. Also proven by hyper milers.

For drivers who mostly drive in town, it's better to go with smaller or lighter wheels so that less energy is used to turn the wheels.

For frequent outstation travellers, a heavier wheel will get you better FC figures as heavier wheels have more momentum and require less energy to keep rolling at a constant speed.


Hi greg,

During idling, the 1.6 wins.

When loaded, the 2.0 wins in FC. I tried by pitting the Forte 1.6EX against Hyundai Sonata NF in heavy foot contest while loaded with passengers and cargo. The Sonata wins.

Anyhow, best FC is achieved through lightfoot. I was just telling kawkawchan that his 2.0SX at certain aspects had better advantage over the 1.6SX in FC.

I hope this explanation helps.

Hi Gen2White,

I replied your question in another thread, forgot which one. You may check. Thanks.

still in run in mode.. so no comment...

but driving in 6speed 1.6, I feel like 2.0!!

I guess is correct that the century sprint from 4speed to 6speed is improve alot... smile_thumbup.gif

are you running on stock super-heavy 17" rims bro?
on paper the improvement in century sprint is around 0.8s which is really impressive smile_thumbup.gif
throw in performance filter & light weight stuffs you can hit below 10s for 1.6L car with > 1,300kg with a driver!
