for that RM100 i can get 550-600KM.

The "jerking" effect is called the CVT rubberband effect. This is what people dislike about having a CVT gearbox.
This effect is only present on unrefined CVT gearboxes. Those good CVTs from Nissan or Toyota usually don't have these obvious traits.

It's the little things that annoy people, though I personally don't mind it 

Priceless! +1 for Proton... then again, of course, if their QC hadn't allow such a thing to happen in the first place.

Am thinking to visit RaceChip, anyone else interested?

After survey Racechip, it's RM1699 including installation. Dyno not included, plug and play only. Tuning done by EA Auto. Including other aftermarket poison, it's about RM3k - RaceChip, boost spring, Works cam gear, Mythelogy pulley. 2~3 hours needed.

Pricewise compared to EU mother site, it is not expensive, according to RaceChip:
Then I asked a mechanic, he asked me why not Unichip.
I looked that up, and it seems to be highly customizable where it can learn and use can reprogram up to 5 fuel maps. Also quite expensive, including the turbo module.

That's when I found RS Tune. They recommend me EFR2T, priced at RM950 including installation and dyno tune to remap fuel+turbo.

Will update more.

just got my EB premium white today...added visor, door moulding, eyelid and window chrome...hehe...

it is normal to have whirling sound when releasing the throttle? and my steering is abit to the left side when going straight (not alignment matter)...need to bring to proton before 1000km right?

mine is also showing VT3 only..no + sign...first tank from SA pump RM 50 and travelled about 160km till lights blinking...now refuel RM102 and will track again...total ODO is 170..

noticed that the pick up is slow..but once you know how to use the accelerator...maintain rpm close to 2 when pickup then the sluggish will be lessen..
here's the thing i've added highlighted in red...

U sure its not 12.4 km/l?

How come fuel consumption so high? Could it be caused by the engine problem with the X1R additive thing that was posted before?

not too worry, it will drop below 10L/100KM (80% highway)

1) Mine too, and was worried about battery almost kong. Now that you confirmed this, I'm thinking to add VR, at least 1 Farad.
2) Mine too. Read about drivers complained that driver and passenger seat will have free play when car accelerate or decelerate, making kik-kuk sound. Sent to SC to remedy.
3) Clutch type CVT...
4) At the center console, next to the hazard light? Activates rear defogger at the same time.
Please read page 1, about not using additive for CFE engines.

For my car, tyre air pressure affects the FC significantly, even on highway.
That time was immediately after 2nd service (6 months @ 10000km), heading south with full passenger, cruising at 9~10L/100km @ 110km/h, so stopped at gas station to bring the air pressure up from 28 to 34 psi. Immediately:
- At 100~120km/h, cruise at 8~9L/100km.
- At 80~90km/h, cruise at 6~7L/100km.

After the trip, city driving FC reduced from 11.8L/100km to ~10.8L/100km.
Yesterday I checked, it was at 10.1L/100km.

does adding GC and VS can do the trick?

My EB very noisy when aircon kick in.  Louder than the fan.

my aircon just kaput again and i'm on the plus highway to penang for the weekend wit my harp for a concert. sigh...
