How to improve low end performance?

[saru04]

That's a nice reply.

I already checked with few of my friends, they confirmed with me that it is the nature of Honda City to be sluggish. They say it will only be sluggish below 2.5k RPM. And its a different technology or something.

So for now I'm just going to rev my car and hope that it'll have some changes.

I'm planning to get Enkei RPF01 but not so soon. Don't plan to change full exhaust system cos it'll be too noisy. The most I'll just change extractor. But also not so soon.

Any stuff you can recommend? Feel free to drop me a PM if its not right to say it here.

i still remember those days in Batu Tiga circuit, the 16a's and B were havoc :)

Till today they are still powerful. 160hp and 186hp for 1.6 litre engine. Compared with City's 1.5 litre with 117hp and Vios's 1NZ-FE with 107hp....

Honda city never use B series engine...old or new, still not powerful..

B16B use for Civic Type R...today type R use 2.0L..

dont compare old vs new..

I know that City never used B series engine. But one of the old one is using D series engine with SOHC VTEC. Coupled with manual transmission, that is still more powerful than those new City.

The modern Type R engine today is K20A....

I'm not comparing old and new cos I do know the difference in power.

Part of me believe that its built this way and another part of me wants more out of it.

I'm going back to Honda service center but before that I really want to try out some other friend's car first.

Well, when you have the new engine, you sacrificed power for fuel efficiency. Same goes for old engines, sacrificed fuel efficiency for power.

Basically its a new car.

From the day I got it, its been that way.

I asked some people in a different forum and they told me the same thing. they say that from 0-30 is horrible.

It is smoother from 40 onwards.

I don't know if its my car or is it all that way.

I'm going back to Honda service center middle of January.

My mileage is approximately 500km.

Could it be my ECU haven't learn my driving style?

Some of my friends told me that the ECU needs to adapt to my driving.

I'm really confused and lost.

What you expect from a new born baby ? Can talk, walk and run ?? Do you engine break in FIRST then only talk...

engine break in doesn't mean ask you drive like mad down or floor the pedal like no body business...just drive a NORMAL but sometime give a little heavier footer to it....'TRAIN' the car...

Currently what i see is that all the parts and component of the car is still virgin and tight :proud:.....do you need to let it loosen bit then it will be smoother...usually most of the car after 10K km only be more optimum in term of power and fuel consumption....

A good way is drive outstation at highway...give a around 100-130km/h...dun street it till 150-180km/h...aside danger you also might get SAMAN

Errr.. i WONDER why you buy this car at the first place since you want more power and somehow knew is sluggish (test drive unit power very good ??)....

With the budget, u can get Cerato, Vios, Inspira, Preve.....what else ?

 

[saru04]

Well, currently "seasoning" the car. :D

Hope for improvement as you guys mentioned.

I went for City because its within my budget. I went for the middle spec City and Honda was giving rebates which makes it cheaper.

What happens if you ask Honda to unlock the stock ECU?

Does it help in anything?

One of my friend told me to unlock it.

Unlock in what sense? Remove speedcut and remove rev cut? On a stock car? Not advisable.

ECU have a preset programming 2 run ur car..

It get inputs from sensors such as oxygen, knocking sensors, etc

From d inputs it control fuel, spark timing, etc so that ur car runs normally

AFAIK, there's nothing to unlock

Hi saru04, when you said sluggish my mind was wondering you comparing with what car? Odd thing is why compare 0-30 and not 0-100? I'd drove this car for a week last time 0-100 in 10-12sec is more than enough for a city daily drive.. Some of the old way that they do for sluggish feeling new car is go back to the SC ask them to adjust lighten for the accelerator pedal. Is just a driver's feeling afterall

 

[saru04]

I'm not too sure myself about the unlock thing.

I was just told to get back to SC and ask them to unlock ECU / unlock DVVT? No idea what it meant.

So called helps solve the problem.

As for the 0-30 I'm not comparing with at any car its just that from 0-30 its sluggish its like the car feels heavy.

Drive a Campro and feel the sluggishness and see.
U will be speechless.

 

[saru04]

I used to drive Gen 2 Campro IAFM and honestly, from 0-80 its smooth to me.

So if I were to compare with Campro IAFM, i think 0-30 for Honda City is worst than Gen 2. LOL.

But after 30, I would say Honda City over Gen 2.

Adjust your aircond lower abit, don't let it work so hard would help abit..

haha campro power wei after 4krpm.. stock setting 4-1 short disturbed the low end torque abit

Gen 2 got normal and CPS only ma not meh.
I don't recall Gen 2 with IAFM. It is smooth but the engine revs slower.
Although, I have not driven a City before.
But a 1.8 Civic is good. ahah (Incomparable)

Wah really wei. After 4k then good dy.
Still, it sucks for city drive ma.
Shifts at 6500rpm really syiok.

For city drive going for 4-2-1 or save money for altezza soon?

Save money for Tezza! :D
Initially wanna do LCP and 421. See how lah.
At least, that's the plan. Haha

I also scratching head what to unlock? Most ECU needs to reprogram for power or piggy to cheat it...

 

[6UE5t]

Remove speed cut is ok even in stock car provided that the car indeed have speed cut and the car indeed can reach much more than the speed cut. I've removed mine. For Honda city though, I don't think it has speed cut as it's not one of the JDM imported cars. For Honda City though to really reach 180kph also will take relatively long time so pretty dangerous to flat out full gas for a long period of time.

Agree though that removing rev limiter is no use and not advisable on std car as it's meant to protect the engine and it won't gain any power as well.

Campro IAFM is an improvement over the original Campro in Gen 2 as it fixes the low rpm torque defect so it's already much better. The original Campro is very lethargic at low-mid rpm.

Honda iVTec la. DVVT is Perodua. Not quite the same technology but very similar concept. It's already enabled (iVtec) on all Honda cars, just a matter of what RPM and what speed it opens up. Nothing to unlock.

Anyway dude, seriously - take the car down to Penang and back and rev it like a mad cow. By the time you get back it'll be ready for first service. Ask to use fully syn oils and then only see how it goes. I have a Honda City in the family and quite frankly I dislike driving it. Not because of the speed or torque, but because of the handling. And I don't see/feel the low end torque problem you're complaining about.

You mean M-Line Gen 2? Only test drive the 1st Generation Gen 2 before only which comes with 1.6L Campro. Not the current M-Line model.

1st Gen, Gen 2. Really sucks to the max. Those is what I call sluggish. 1.3 Campro IAFM Saga Blm is better.

auto cars always sluggish around that speed..

and Honda doesn't use DVVT.. it uses i-VTEC

Must be Honda made a mistake and plonked in 1.5L 3SZVE inside. DVVT Kicked in Yo!
