if i am not mistaken ..someone mention at this thread can remap ECU atproton SC to improve responsiveness

mine was goodyear tye as well...

handling is not up to my expectation ..driving 100 feeling is not same as previous persona

thinking to upgrade to 195/55/R15 Potenza RE003 once this tyre habis (probably another 1 and half year story)

done remap at senaxis. Pickup is instant

lol what ? remap seriously ? how can it be ? No matter how the throttle still will lag abit compare old persona.

They only can reset the ecu only , update the ecu (reflash to new version) in Proton SC.

Handling definitely sure is lose as previous persona.

Comparsion
new persona is using torsion beam in rear
new persona tyre width ori 185
new persona car height is high

old persona is using multilink
old persona tyre width ori 195
old persona car height is low.

if u cornering in 100 speed definitely u will lost control abit which mean not stable

So far my goodyear triplemax work better than silverstone.

I don't think they do remap. They only can do reset or reflash only. stop at traffic press little throttle the car instantly move?

I did mine at senaxis too.

To be honest, i dunno if it's remap or not, but i saw them bringing a laptop with cables to the car. Maybe it could be as you say, reset or update ECU. I didn't wanna get too close to the foreman. Sked make him feel uncomfortable.

But my previous delay was about 1-1.5s and now it's less than 1s. which is now an acceptable range for me. It is not immediate but at least it's not super bad. The previous delay makes driving really difficult. Traffic light time, the lead car sure leave a huge gap when green light. Now easier to catch up.

Btw, I'm on Michelin PS3 195/55R15. At first feel not much difference (since i was stuck in jam the entire time and it's not raining) but ytd i took it for highway ride, can really feel the car grip the floor. Only thing is persona vvt too tall, the body roll quite noticeable on corners. More noticeable compared to my old blm. That being said, it still handles better than my blm and lesser nvh

Edit: previous delay make driving manual so difficult, esp when on slope, and i wanna feed the car some gas before lifting clutch, but dunno when the gas will come. Now at least can manage that.

>cvt
found your problem there.
you need the manual transmission.

haha Senaxis is good SC.

Ya its bring the laptop with obd2 connection car. It will be reset or update only. haha just get close to the foreman, ask them they will tell what they doing , then u can learn.

haha ya, manual i heard that a lot member complaint of delay , it not like myvi previous old gen once u press the pedal wrooom vroom fly liao. Great to hear that.

Nice tyre u have, yes our car is too tall so bodyroll will be very noticeable.

lol i think he need to adapt it or he need change to 4 AT.

So far ur cvt fc good ?

1st day only ..drove almost 100km

no idea on FC yet

oh after first 1k service come back and tell us. Hopefully wont disappoint u la

Did my TCU "Restting". For everyone that concern about slow throttle response, jerk or my case(wheel spin). It solve by resetting the to an updated program to TCU. it did not do anything to the ECU.
i done it at senaxis too. So many of us here went to senaxis, the amoi there also ask me "you look ar forum ar?"

So what issue has it solve
1. originally, if you put in D from stop the car will move slightly, if you gas a little bit, it will jerk.
2. the reason we feel jerk is actually a lot of torque from CVT given to the tires, an acceleration too fast for our comfort we call it "jerk". The remap solve this, so i dont feel that jerk, instead now i feel a linear acceleration instead of wheel spin or jerk.
3. my wheels used to spin when i floor it either in L or D, now no more. since my wheel dosent spin, translate to very very slight 0-50kph slower. im not a racer, im happy to have linear acceleration.

this remapping wont solve for newer cars, since anyhow is a clutch CVT, you wont get the response of an actual manual transmission or even 4 AT. There is always like a 0.5 sec delay,is a CVT.

My persona was the 2016 batch so should benefit me right? Is this for manual or auto btw? If it really improves I am gonna do a service booking at senaxis

my persona is 2016 1st batch, you should get the fix. manual's TCU is the human hand

I did wheel spin by accident too. Haha. But i blame shitty footwork and silverstone tires. At slope, scared roll down, so i fed too much gas and caused slight wheelspin. So far no more such encounter. Hehe

Just did 30k service at puchong jaya branch yesterday, Only managed to recorded 24k km @18 months. Changed oil, fuel filter, spark plug, coolant.. fees rm400++, luckily is free.
Cvt car summore got hill assist, vsc the car wont be sporty like manual car no matter how u tuned la...treat the pickup delay as safety features lo...my previous zero delay persona se always tend to bang pondok, divider 1, but my new persona touch wood still free from bumper scratches after driving for 1 1/2 years.
Ya the silverstone tyre so so but if u bawak biasa ok jer...yg tak ok tu is when after 2 years the tire wear ady then no choice must change. So if tyre still new dun waste money la tukar so fast, unless u r rich la dun mind to spend rm1000 to change better tyre mentah mentah. Race type tyre like ps3 or re03 of coz better handling grip but they will wear even faster. I will change all 4 to 195 55 r15 cc6 when my silverstone rosak but now still ok never skid before, just maybe im old man la driving slow not fast & furious as u guys youngster...

Well, the car is connected to the ground through 4 tires. If the tires not gripping the ground, all sorts of active safety not going to help you. when things go wrong, you can only trust airbag and hpf. The repair cost could easily be even more expensive.

I dun mind spending more on tires regardless they wear out fast or not because i don't throw corners and i don't drive a lot. All my tires except goodyear duraplus is changed because reach 4 yrs lifespan before i ran out of threadmarks (including michelin xm2).

During my days with silverstone, my car skidded on plenty occasion. When driving under rain, when braking and etc. Doesn't even have to be heavy rain, as long as the floor is wet, and you are not braking gradually, the tires will lockup.

Had enough of these and i told myself, highest priority investment in car, will always be a good set of tires. Other things, i can live with. Malaysia is constantly raining so wet grip in tires is important, something that silverstone is severely lacking in. It's not the high speed corner performance that i seek, but ability to brake in any condition (dry or wet) in case of emergencies.

Just change the tyre dont wait or else drive very slow or safety depend on condition. Silverstone tyre is like tat , wet grip will make u lose confident. But dry grip should be ok , hard braking I do doubt on silverstone.

Hi fellow Persona drivers. Anyone ever do soundproofing to their car? If yes, where did you do it and how much is the damage? Thanks
