regarding A/T pica, did any1 feel that it somehow has more than 4 gears? (think i've read in another post on this... now i'm feeling it too) firstly is when engaged on gear 3: - start off on gear 1, then gear 2 (each changing gear at around 2.7krpm) - then during gear 3, i stepped on the accelerator slightly harder, rpm goes to 3k - the rpm will then drop to 2.7k, power maintains (doesn't feel like a gear shift) - then finally it changes to the last gear where the rpm further drops to 2.3k and i reach the cruising speed of 80km/h another "additional" gear when engaged on gear 4: - while maintaining at 80km/h with rpm at 2.3k going on str8 road - then i engage a standard flyover with same speed - while maintaining my right foot and reach about 1/3 of the slope - engine suddenly gives higher power and rpm increases to 2.8k where i'm still at 80km/h (doesn't feel like gear shift) i'm wondering if it's the ECU that's causing these? like telling the injector to input more petrol to provide a combustion to achieve a certain torque/power determined by our right foot... what i dun get is that if the gearbox's gear ratios or shaft (the things that reflex the rpm on our tachometer?) are fixed, how can it change the rpm even if engaged in the same gear? Your queries is too complex.. I also don;t know what's the answer, but I got similar experience as you.. - then during gear 3, i stepped on the accelerator slightly harder, rpm goes to 3k - the rpm will then drop to 2.7k, power maintains (doesn't feel like a gear shift)Sometimes I realise when I accelerate harder at gear 3, the rpm doesn't go up, but the speedo keep going up.. I also realise that if you apply a constant pressure on the accelerator, the ECU will change your gear at a constant rpm.. I don't know how to describe, but if you vary your pressure on the accelerator to driving a manual car, you can simulate the ECU to change at a higher rpm.. I think the ECU is intelligent.. When I first drove the car, if I want more power, I just step on the accelerator.. But the rpm doesn't go higher than 3rpm.. Now then I know about this "feature".. I think there's much more to know about the AT transmission.. Thanks to Joey for his advice on this issue..

Hi guys.. Just to share my feedback over the past weekend.. In terms of FC, my first tank of petrol after the QF managed to clock in 364km based on 25.47Ltr of petrol.. So FC is 14.29km/ltr.. And this FC is based on full load with air con coz I've been driving on a full load of passengers throughout the weekend.. 14.29km/ltr is an improvement of 2km/ltr from the initial 12+km/ltr.. In terms of power, I was told by one of our fellow picas that QF takes time to run in.. But what I experience from this 2 days is surprise.. For my pica, from 1 to 2.5krpm, nothing much happens.. Just like normal driving.. But higher power compared to stock.. But after 2.5krpm, if you are willingly to step on it, the power actually comes in.. Before QF, my pica seems to have lost power after 3krpm, but after QF, it just keeps going until 4krpm.. Didn't went on any further.. But the power it exhibits during this range is I didn't experience something like this before QF.. I'm still expecting some changes as a fellow pica pointed out the time needed for run in.. Hopefully, the improvement comes in from the FC.. But overall, if the FC continues to be in the region of 14km/ltr and above, I should say that the QF is really awesome.. It can help you save petrol in the lower rpm, yet give you power in the higher rpm.. I feel that it's a great mod.. Thanks to all the pica bros whom I'm PM in order to find out more about QF.. They have been providing valuable feedback and info which makes me decide to go for the QF.. everyone.. thanks picanyeo for the further feedbacks regarding QF. i've already decided to go for QF and had paid deposit last sat when i first met joey. he is really a nice guy with patience and lots of experience to share which comes with a smile. lol joey even enlightened me on some issues with my car, now i can go back C&C to pin-point the problem. too bad my budget is already over for this month, if not i would have done the QF earlier... hmmm... having to reach 3krpm to maintain 100km/h seems abit too stressful for our A/T pica... is pica meant to be so stressed out during high speed? anyone can share their experience driving a pica through NSH? My fren told me that he drove 130~150km/h along NSH for a period of 2+hrs without any issue for his M/T pica... (3+yr old pica) sounds scary to me though... Mine is also 3rpm at 100km/hr.. So far no change yet.. I think the reason may be our engine capacity is on the lower side.. So while 100km/hr may be normal for bigger capacity cars, it may found stressed on our pica.. And in addition, perhaps our transmission is AT.. I read from the specs that MT pica have a higher stop speed than AT.. 154km/hr vs 145km/hr.. Could this be a reason MT pica experience a lower rpm at 100km/hr compared to AT?

By the way, I a little.. Just to check.. Is there any pica who has changed their exhaust pipe? Just wondering, coz until now, I haven't seen one yet..

Hi guys, after reading all the input here... I have decided to do the QF for my new Rio 1.4A as well... My 'pure' rio gog to get poison-ed soon... :x I assume you haven't done anything to your new rio? So qf will be the starting point.. There will be more items and gadgets to add on later.. be it cosmetic or performance based.. At first, when I started reading this forum, I was puzzled to read this word "poison" in this forum.. Now I;m starting to know why.. It's not called poison for nothing.. yeah... its the feeling of "wow! that's cool! i want to have it on my ride as well!" and it'll just keep on going... changing to a new ride will only be another beginning... lol

But have to save up first also... $_$

Wiao! Alot of replys. I am slow.. LOL.... Mine's a F/L manual about 7months old clocking 15000 plus km on the odo. Well, I guess i cannot feel the difference becos during the running-in, i have already been revving and giving it a hard revving to my pica liao. so somehow b4 n after the QF i feel that everything is like the same. Can only say that it is really smoother. But recently due to the promotion by caltex, i went to pump Platinum 98. Either it is just own thinking, but i personally feel the extra ooozmh and power in my ride. I guess maybe QF works really well with high octane petrol? Anyway i agree that maybe more mods can be done to feel the extra ooze. Esp, i believe open-pod plus CAI will do just fine. LEgally too.. i try pump 98 at caltex but feel the same as 95. this friday i going harmony motor, hope joey can help test a bit. Cool... Let us noe the result bro. BUt seriously can feel that the platinum 98 is really responsive.. I dun nid to change gear so often...

can redeem $5 platinum 98 voucher at caltex now rite? i tried to redeem after adding 95 petrol, they say i could redeem on the spot only if i pump 98... dunno what's the "voucher" all about... hmmm... i ever tried driving off like how a usual 1.5~1.6L car will accelerate, my fc clocked around 10.5km/l... seems like picas still have to stick to lane 2 and above, most cars will just overtake me if i take lane 1... or we'll just suffer lousy fc if we try to close up the gap. anyway, its still a budget but good car to own for a beginner like me, where i can meet so many nice bros in this forum. Cheers! hehe Cheers man.. Agree with u that it is a good car to start off with. No regrets. Yeah, promotion is only for platinum 98. That time when i pump after a $15 disscount plus a total of 10percent off.. Full tank only cost me $35...

I noticed that most of the bros who share their experience here are driving picas... Does it mean the effect is less obvious/ useful for other models such as Rios? Any riosters here care to share more?

Any riosters here care to share more? hi danielkoh, from what i've read, QF should benefit Korean cars more than most other makes, by optimizing the fuel/air mixture ratio input following by a more accurate ignition timing. (Korean makes have richer mixture by default, so QF actually leans it) sry... maybe i might be getting abit too naggy by repeating... lol but i find this information very realistic. (although i've not went for QF yet! but i've placed my deposit. lol) will be just as glad if there can be more frens owning other kia models to join us and share ur feedbacks as well.

Wah.. 98 petrol got more power issit? Must give it a try on my next pump.. Calculated that my petrol bill will increase by around $12 if I use 98 instead of 95.. Must see what's the difference.. If the difference is significant, using 98 will be worth the money.. But normally, our pica does not require a petrol with a high octane content.. So how will 98 help to increase power? Does it have anything to do with the QF?

In terms of power delivery and the feel, i think that 98 is better but mileage I doubt it is better or it can be just the same. The promo is ending 15th July.

Not too sure how to explain, but 98 will give the enngine, a better combustion, hence better responsiveness and perhaps in return a slight better power. I guess QF works in a way that the engine are able to burn the fuel better?

The promo is ending 15th July. as posted. i dun really feel the dif, esp in mileage, i oso seldom rev up my car so 98 at low end is almost like 95. if u wan to get mileage vs grade, i think 95 is the best bet btw, i use to use SPC and convert to Caltex just before QF, SPC so far give the best mileage bu caltex so far give the best power same grade

Strangely, after the QF I find that my Pica runs best on Shell 95, as compared to 98 or V-Power...

minimum octane is 95 as stated by Joey before.
Qfed experience best felt in high end.
U can actually feel more power kicking in. With 98 platinum... power la..
But still loose to those bigger cc car during low gear. But once gear 4 and above.. Hard to say liao la.! But 1.6 and above sure smell smoke!!

I think V power is really power.. Pickup will improve.. I haven't try it on my pica before.. But I have tried it on my motorcycle when I was riding it.. The pickup really improved, although top speed still remains the same..
But my motorcycle is using carb.. I don't know if using fuel injectors will have a difference.. It's a good point to consider but I think I'll try 98 instead.. Must save $$$..
