Throttle Controller or Exhaust?

[chershen]

the title straddles btw 2 realms but i posted it here. working within a budget, i am looking at a throttle controller (tc) or an exhaust system. noting that my ride is just the humble 318i, just want to seek the experienced opinions on the two and which is a more viable option.

off the cuff, i reckon tc clears that lag that comes with the car and will give a quicker response not related to power gain. i had a sb on my previous ride and these newer ones [with controllable modes] are really quite attractive [the pivot one looks damn swee].

the exhaust would prob only pump out an additional 5-7% bhp gain? but i guess the "emo" bhp gain would be significant esp. when one hears the vroom vroom coming out from the end.

any views will be the most useful to help frame my decision.

many thanks!

why don't you do a reflash cos i heard that your 318 is easily tuned BACK to 320.
best would be exhaust first then reflash .... vroom vroom

Re: Throttle Controller or Exhaust?

the best thing u shud do is get rid of ur mid pipe n change ur exos...n headers...ur throttle will becoms a lot more sensitive...

 

[chershen]

Re: Throttle Controller or Exhaust?

2 votes for exhaust then. reflash i am really not too sure at this juncture.

many thanks.

any other perspective?

or maybe,

Get a velocity....i think bro wolf73 selling his......
then operate exhaust...........

cheers

Hello you want his low end to go down the drain? haha! too fast flow on a smaller block will result to step n step, lots of sound but no GO! :chinese: :laughlik:

You can try a stock E90 330 muffler with valve controller which helps regulate the flow output at varies RPM/speed. If you are keen I know someone selling...just leave me a PM.

Re: Throttle Controller or Exhaust?

I wld go for a throttle controller coz day in day out, what make u enjoy or get sick of the car is its responsiveness. It is much cheaqper than a exhaust mod too. Exhaust for NA cars is really juz sound with very marginal gain. Worst still, u might expeience cabin drone if u buy the wrong exhaust.

Re: Throttle Controller or Exhaust?

Beg to differ.

Car is a 318 in question.

The perceived marginal power gain on trottle signal ampliers are butt-feel - for those who fears FCs, there are plenty on sale in the Bazaar folder (I wonder why)....

At least exhaust mods fulfil the aesthetics aspect, if little power gain, depending on what you do.

Re: Throttle Controller or Exhaust?

All u need to do is whack full throttle for a couple days. After that, the car will be responsive toward throttle input.

 

[chershen]

Re: Throttle Controller or Exhaust?

many thanks all for the perspective.

the differing views are testament to the tension i have within myself, and some others i guess.

Re: Throttle Controller or Exhaust?

just throw that spare wheel, baby seat, umbrella etc out of ur car. then sprint off at the red light 1 second earlier than others. sure win one

 

[chershen]

Re: Throttle Controller or Exhaust?

spare wheel - checked, no spare wheel.
baby seat - checked, no baby seat.
umbrella - checked, must have if not get wet.

so at least 60% faster.

Chershen,

bhp gain really needs good mods and again what is your expectation for bhp gains. Throttle response do not give bhp(from my knowledge), just gives a better feel when driving without lagging.

Starting with ECU refresh/Piggyback/etc... will lead to exhaust modification. once you have bhp gain, brakes/suspension/plugs/filters is important too....

So it all depends on your budget to move up bhp.

I did my velocity and felt good.... after brainwahing... i decided to do PB. (Thanks to willman ) never regret as of now To have a better feel, i'm awaiting for my exhaust to arrive and that's where i can tell you my feel.

In short, dependent on budget for all mods.

Cheers and happy modding.

Re: Throttle Controller or Exhaust?

if set bhp gain aside ... how is the throttle response between

a. velocity profile 1,2,3,4

b. pbx throttle remapping 30%,60%,100% ?

Wolf, r u sure? He is driving 318, which is a detuned 2L leh.

yup, nothing much can do to really push this 4 cyc unless SC.....

probably max if can get 10hp, happy liao.........(if)






cheers

Probably la..... SC/TC is easiest to get bhp.

Not sure of ECU flash because never tried

Other than SC/TC (u have mentioned), nothing can be done. N46B20 for 318 & 320 using two different intake manifold with different DISA. Change of hardware also no use unless ECU recognise it as 320.

TS, if factory tyre is run-flat, change it out & butt feel will improve.

something i learn again from this forum. Thanks for the knowledge

Now i know what are the mods i too can start budgeting

In my opinion, increasing of 5-7% bhp won't make much diff, maybe instead of getting max speed of 200km/h now can go 210km/h? How often do you drive at that range? 5-7% gain in bhp does not equates to same amount of torgue increase. The only thing you gain most is probably the better sound coming out from the exhaust if thats what you really want. So for me, I would go for the Throttle controller for better day to day drive.
