its normal. one of abcm function. mr assholer, i think ur upshift at 2.5k rpm is better than prev upshift to 3krpm. just maintain ur current upshift style,it will balance between fc n power.

just upshift beyond 2.5krpm when needed such as overtaking,hill climbing n when during carry highload.

just copy n paste from eb forum,q n a with kristoff about the lag.

Q. You have mentioned that the clutch is almost completely open while standing still with D engaged, is this the prime reason of slight lagging when slowly pressing the gas to move?

A. Yes, if you release the brake and im
mediately press the gas, this is the case. It is always better not to press the gas immediately unless you have to (uphill), you will notive less delay. That it isn't superagressive at launch (if you would mean this by lag) is calibration, it isto preserve both engine and CVT. it is called torque reduction, the engines power delivery is minimized, although full trottle.

as punch representative reply,in simple term,when u r already in D,let the car crawl 1st on its own before apply throttle,unless the situation demand it.

if u are at neutral, engage to D a bit earlier, maybe half a second than normal at/torque converter cvt to let the clutch builds its pressure.

but dont expect the rpm will raise hand in hand with speed during stop n go situation cuz its clutch type cvt,n it does behave like manual trans.

low speed jerking will.be lesser overtime,but it wont completely gone.

yup,its due to clutch,like u r driving manual box in 1st gear delay unlesa the clutch is fully open/release. not evidence if using torque converter.

it will be a pain transition to those familiar with torque conv type.

i think it needs not only tcu update,but ecu update also. since its using bosch motronic,totally new n diff from prev conti easyu 32bit controller(which already have its last update earlier this year to solve chocking prob due to cold start n reduce launch delay), i think it will take more time to calibrate it. dunno whether they will come out with it or not or it will be that apparent.

by the way, when u service ur iriz,ask them to check with padt n check whether ir tcu is using the latest firmware. if not,ask them to reflash it.

it only can be done at branch sc though.

i feel the delay worst if u r in neutral try to slot to D n press the throttle immidiately. if u already in D with footbrake,the delay is lesser,especially if u let it crawl 1st. hopefully prtn n punch will manage to solve it completely. but it seems hard due to clutch action. nevertheless,they shud try to solve it.

can stop smiling reading the link.

cant stop smiling,sorry,typo :-)

the issue is just clutch based cvt behaviour is diff than other makes that used torque conv at n cvt.

it moves,it just that people expect the rpm will raise hand in hand with speed rise,in iriz,the rpm can shoot easily to 2k rpm before the speed rise,n sometimes u can over rev since u think it didnt move fast. when u adapt to iys character,its not that hard,it just the transition make it hard. thats why some manufacturer like toyota did put step auto mode as standard to.behave like conv auto,so that people will feel familiar as normal auto.

well,its not easy to satisfy everyone,but i think,prtn will try to fulfill all needs as best as it could.

prtn isnt a strong brand, any flaw will be a big one. its not bad actually to prtn coz they will try harder to make a perfect car though. i believe most comments cuz people want prtn to be better than previous,n better than others. something we can be proud of.

about the cvt sound,yes,i do agree its noisy compare to other type cvt,it just quieter than flx n preve.

there is ecu reflash update early this year for conti ecu iafm+ cvt to counter the semput thing.

just sharing info. if u want to drive efficiently,u can gauge by using instant fc. since iriz dont have eco indicator,u can used that to gauge which rpm/speed is the best to get most fc. after u learn it,then u already know how to drive it efficiently. not only for iriz actually,for any car that has instant fc info.

no speed limit. well,it is known that iriz 5th gear is tall, even taller than prev iafm+ n campro 1.3,to help reduce rpm during cruising for better fc,but since its 1.3,n its heavy by the way,plus 4 adults onboard, so u need to downshift to 4th gear to regain momentum, even downshift to 3rd if really needed for fast overtaking, unless it is 1.6 mt.

notwithstanding that the engine still tight. being a cast iron engine,it takes time to mature,in fc n speed. notmally,after 10k onwards,it will be fully optimised.

the new ecu n tcu reflash shud make the car creep faster in D,means the clutch open faster but the clutch effect still there cuz its a clutch based cvt afterall. n it will hold on the low ratio a bit longer than prev setting.

to gauge whether iriz 1.6cvt is superslow spokes or not,u need someone to drive side by side with other car to gauge it rather using feeling. take for example myvi 1.5 at,drive along side with iriz 1.6cvt. from stop n go,both rev at 2k rpm max every gear and try to measure how long actually myvi manage to leave iriz behind. if 2 or 3 cars length iriz is behind myvi,then iriz is really slow spoke aka siput sedut then :-). maybe some shud try,just for fun though.

mr ruffstuff,i think its quite weird situation happened during ur reversing on flat road. if during steep road,its understandable.

afaik,during reverse,it used planetary gear to give fix ratio(meaning not using cvt pulley at all). so,reversing on flat road,u shud let it creep 1st n rev a bit only,no need to rev high as forward gear. but its a bit tricky if slope though.

but i think u shud send it for checkup, n check whether u r already at latest ecu n tcu update or not during 1k service. i know ur chasis isnt involve according to internal circulation,but no harm checking though

tqvm,my mistakes,u r correct.the pulley does turn in opposite direction,n planetary gear give it fixed ratio. forward n reverse using diff clutch pack. maybe what happened to mr ruffstuff due to forward n reverse clutch action, maybe its forward clutch disengage a bit late n causing reverse clutch engage late. maybe recalibration of tcu could solve it.

if u r opt for semi syn or fully syn,i recommend 5w 30 engine oil for better fuel economy. for fully,there r many opt,but the cost really high. for semi,i think shell has 4l 5w 30 semi. petronas only 10w 30 at the moment for semi,n mostly 3l,4l is quite rare. u need to top up 1l 10w 30 though. dunno bout others semi synth,but for the moment ay petrol station,only found shell 5w30 available for semi.

in branch sc,only petronas oil is offered. iinm,fully offered is 15w 50 rating which im not recommend,too heavy actually for new car. u can choose 10w 30 semi syn though.

but they did allow u to bring any reputable brand engine oil. branch sc allow that,but i heard that some sc,most prob dealer sc,didnt allow u to bring outside eo.

5w 30 is still the best for me,for price n performance. unless u like to rev hard,always drive fast, 5w 40 will suit the way u drive.

to save some money,used semi syn cuz if u used fully,its still the same 10k or 6 month oil change. want to save more,just stick with mineral oil provided. can spend extra cash for tyre upgrade.

it depends on ur pocket though. if u want fully syn,5w 40 rating is really easier to find,5w 30 also available.

good if its already available in petronas. never seen they put it on shelf at the petronas petrol kiosk everytime i refueling. maybe just not my luck.

so the options are wider now. tq for the info

maybe u can check ur rear view mirror whether it fits properly. sometimes it can rattle a bit if not fit securely. give it a try. just a suggestion,not solution though coz rattling issue is hard to find the source.

dunno bout latest policy though. maybe they dont want it to be a reason for engine fault.

prev, you can bring your own eo as long as its from reputable company.

maybe this time they want to be extra cautions.

check ur battery connector whether it loose or not. if loose,retighten back
