if there is no VTC on i-vtec... why call it intelligent-vtec in the first place...

the timing control is the essential part of a revolution which is why Honda decided to have a new name for it instead of their older VTEC naming....the variable valve timing is there to help optimize flow into the combustion at lower rev ranges to maximize power output at all rev ranges where the design of VTEC did not really take care of...

i don't know where you are going to with this...

in terms of the vtec cam kick feel of the b16b, b18c, k20ar.... i can tell you it's not there whatever you do... the l15a7 is built to be a consumer engine... not an outright performance engine... else, it won't be outputting only a measly 120ps for a 1.5l...even the b16b 1.6lit had in excess of 160 horse on tap which is just a notch above 100 horse per liter...so, if you expect the feel of the performance engines...you'll be in for some heavy disappointments...

and the VTEC will engage in all the gears and not 5th alone... if you plant your pedal into the carpet from standstill... every gear will shift up around 6.5k revs.. it depends on your throttle inputs as i said before... this L series engine gives you the feel of a slight surge when the VTEC engages and not the feel of a kick like from it's big brothers... you just feel the power keeps going on rather smoothly rather than tapering off until it upshifts...even if it only engages in 5th, it's a bit rather pointless as you say it will be around 4.5 to 5k revs which means the car is most likely traveling above 160kph already and acceleration at that point upwards is dang slow.. i doubt you can feel anything at all... if there is anything to be felt at all... it's during the first and 2nd gear pulls.. even 3rd feels a bit weak already...

so, if it's a throttle problem... it is the same as any car.. if you floor a vios or a city / jazz all the time... it is going to be the same outcome which means more visits to your friendly local drinking hole...

i read it from here http://asia.vtec.net/Reviews/4GCityPrev/index.htm . Although it is honda city, the engine is the same L15A i-vtec.

a paragraph excerpts :



so, L-series and R-series doesn't have VTC. 

not sure how true it is though, maybe someone can shed some light on this.

I'm coming from this:



2012 Honda Fit Manual i-VTEC Highway Pull

And i've tried pedal to the metal from D, it'll actually shift at about 3.5k rpm max.. Well, its are all maybe and this vtec thing is very new to me though.. still gathering inputs..

i don't think the myvi's shift is what you actually call smoother... it is just that the 5 speeder shifts up and down a lot more actively making you feel that the autobox is like a bit jerky... sometimes, it is tough because when i expect it to kick down 1 gear, it doesn't.... sometimes i wish it would stay in that gear and then it kicks down due to the gradient sensor sensing it is going up an incline... sometimes you wish it will hold that gear longer and then it decides to shift up and then you depress the throttle to get the car to accelerate up to speed faster to compensate and it decides to drop a gear for you and the car surges forward a little faster than you want... it's pretty much got a mind of it's own...

for me, it's the feeling of gear-changing that is jerking, not of gear-hunting.
i would rate the gear-changing jerkiness is lesser that of auto gen2 1.6L HL, but higher than that of auto myvi 1.3L premium.

i've driven the myvi before... at different conditions the shift quality differs... at it's worst... i do feel that the myvi is more or less the same as the jazz...

when i posted that statement... i did not meant to refer to gear hunting issue specifically but rather if you take into account of how the TCU on the jazz behaves and the availability of it's ratios compared to the myvi... the way the TCU tries to upshift whenever possible especially at low speed low throttle condition causes the occupants to feel a certain jerkiness to it when it upshifts...and it doesn't help that while costing in the highest gear possible under light loads that it drops a gear or two in some instances when more throttle is fed...

if you run the car with more throttle and get it to shift at a higher point... the jerkiness is not felt that much... although it's a matter of fine tuning how it shifts... but this is no Lexus by all means... so, it's not really something to niggle on for a sub 80k car...

on the myvi... it only has 4 ratios to go around meaning the shifts have to be spread more sparsely and shift point are generally a little more higher...

ok, i got it..or perhaps u can correct me:

our auto jazz has 5gears, while auto myvi has 4gears.

say to achieve 0 to 40km/h in normal manner,
jazz may shift 2gears, while myvi only 1gear.
the jerkiness in jazz is due to these 2gears.

is my understanding right?

partly...

for what i have driven before... i do feel the myvi drags a gear for a tad more longer.. if it shifts at lower revs it might have the same issues....

on another note, not quite directly related... i mean that the frequency of the box slugging in between gears makes you feel it more frequently.. maybe that impairs your perception on how the box shifts...

wow...! you do travel quite often... refueled also every other day...

nah... it doesn't happen..

i even went as far as asking for a drain of the ATF and change it during the 2nd service to see if it's better but end up it's the same.... i used back Honda's DW1 ATF as they did not allow me to use the redline ATF that i brought along...

Yup totally agree with you, after 4 days of driving my baby seems that the gear change is not as smooth as my CVT City. Kinda miss the smooth gear transition

But the car overall is a great drive, good on corners and quite stable. Guess will have to force myself to get used to the gear changes.

Heard from my SA that the new Jazz will come with CVT, oh well too bad.

CVT has no gears... in fact... it has infinite gears hence you feel a seamless rubber band like feeling to it as it doesn't shift physically between gear to gear like normal manual, DSG or torque converter autoboxes does....

it does have it's good and bad however like all other things... and you can't just change it with normal ATF like what most of the first gen jazz and city owners did outside of honda SC and then had their CVT box wrecked because of negligence..

i need to double read croomaniac & butthead's comments to understand more 

i tried to feel the "vtec kick in yo" but i couldnt..hahaha

Hmm city driving 10l/100 km

that was KL-PJ peak hour crawling jam 

maybe u can try a hybrid then..
