Same here

Hi guys just wanna ask something..do I really need to do the chamber adjustment..pls refer to the pic attached..normally what do ppl do and change? How much does it cost..


Attached thumbnail(s)

heh. this issue. Ive been conned abt this..b4 i got my own tyre mechanic
for chamber thingy, the only thing tht u need to purchase if Chamber screw nuts.
usually if u go to tyre shop..n do chamber..the cost they charged u always higher than its supposed to be.
Chamber nut is only around RM15 for each. n tht thing above is just to adjust ur car's "leg" whether u want it to be straight | | or spread out like / \ .. this may cost like balancing price..
spread out for layan cornering..n straight is for high speed highway driving..

RM15 is cheap..the shop quote me RM30+ for 1screw..

i just test drive the persona the other day, i found that the engine is extremely quiet and quiet inside too... but...

the accelerator pedal seems too soft and not responsive i.e. tap a bit nothing happens but press harder abit then the engine suddenly rev to 6-7k rpm

hard to control the car!

I because of driven by wire.....Delay like 1 sec...
Install VS and grounding cable...improved it...

I would like to know how VS and grounding cable is able to improve drive by wire throttle when the electric signal is actually sent to the throttle body not it does not require a lot of current..

Edit
Btw i saw this on sale.

Any sifu can explain how does this works to improve the throttle response compared to VS + Grounding cable??
Cos my neighbour have installed this in his civic, and i can really feel the difference of throttle response by changing between settings such as eco, normal and power.. Throttle response at SP7 level is instantaneous and very good.. Slight tap of accelerator also can feel the car lunging forward..

Persona grounding not so good...so...the VS (DIY Version) + grounding give stable current to spark plug and reduce power loss during air cond compressor kick in. I installed mine and it really help my IAFM Persona (MT)... I not sure about AT Persona...

Maybe other can give comment.

LOL I will post some before and after results when i get my car then..

yup. VS works on my iafm MT also.
next aim, grounding cable, plug cable, and spark plugs.. mayb after the 3rd service.. still a long time..

average calculation for hiway and city driving..including driving at hulu langat-jelebu snake and hill road..huhu..

I gonna buy PE car soon, which bank offer best interest rate for 5 years? currently get 3.5% from public bank for 5 years..any suggestion??

i kept reading about VS etc.. is it really good? btw.. doesn't it void the warranty?

My fren just bought Persona Elegance Hi-Line....I can say its very-very nice, NVH is very good...just that rear seat not really comfortable like wira...It just not enough padding for thigh..or perhaps it just me.

no need to wait 1 year, my car 3 months old already have the sound, i think is because i always bring alot heavy thing at behind, i guess is either the absorber, spring or the boost at the lower arm

All Persona except 1st batch comes with IAFM...
which means using Coil on top of Spark Plug.
No Plug Cable tho.
