i plan to install throttle controller in my persona..but dunno is it useful or not lo..pls help

so tat means is can increase performance.rite?

nope
just increase the thottle respond only
u will notice dbw system have certain lag when compare with old school direct cable

recently my setup for bullet and midbox,the distance between bullet and midbox is around 4inch..if i change the distance to 12inch,is it will affect the power?

means if i din install throttle controller,i oso can use the way like press the pedal more deeply to minus the lag,rite?

yes can think this way

if you use controller, it will send 2/3 throttle signal when you press that suppose to open 1/3 of the throttle

the controller will cheat the ecu. so you feel more power

so tat means install throttle controller is tipu myself lo??

there is another one, cheaper shadow e-drive throttle controller

any difference for cheap and expensive?so all of u think is worth to install?

Useful for people want to eliminate throttle lag.

Doesn't increase performance at all.

btw, increase throttle respond only need rm50 what.. no need of this specific gadget.. however, the advantage of this item is that you can alter the setting on the fly, no need to adjust throttle offset using PDT everytime..

I thought TS was asking based on his persona, no?

And ETC is not about adjusting throttle offset, so you are commenting out of context.

Without ETC, i need to play with throttle offset to get similar result, no?

this seems one good option.
But me like the idea of standalone

Similar, but not identical. ETC doesn't play around with the offset. But you can have both done and still work perfectly.
The only draw back is that, the calibration of the ETC (S.O.P. after installation) may render the improvement from the throttle off set adjustment useless.

Why driving harder is not the same as what you can gain from using ETC in Sport mode? It's all about 'throttling rate' - the slope of the throttle graph (above).

The ECU reads how aggressive the pedal is depressed and interpret this as 'throttling rate', or pedal deflection rate. Higher throttling rate triggers aggressive ignition timing advance, thus improving the power output of the engine in response to the footwork.

The sensation of the relationship between footwork and engine behavior, is called throttle response. Good throttle response is described as getting satisfactory engine response while being light footed.

Being heavy footed without modifying the throttle graph may achieve the same throttling rate. However, this doesn't make the throttle more responsive, you are just driving it harder.


Why "throttle off-set adjustment a.k.a. PDT" (famous among campro users) is different from a proper ETC (electronic throttle controller)?

What's "throttle offset adjustment"? Forcing the ECU to learn a lower V as 0% pedal depression. Result is that, at 0% actual depression, ECU is reading it as 'being depressed at a certain %". At any deeper depression, the ECU reads higher.

1) Effect is minimal for a problem-free adjustment
2) Can only reduce throttle lag, not the signal profile.
2) Greater effect comes with draw-backs.
3) No on-the-fly adjustment

This is a factory default 'trick' for the service engineer to solve unstable idling, not a S.O.P. to improve the throttle response.

JUST LIKE ADJUSTING THE CABLE FREE PLAY.


The mechanical-equivalent of electronic throttle controller (ETC) is an undersized throttle pulley, NOT by adjusting the throttle cable free play.

i love the SPORTS mode......definately faster throttle responses

Aiyah, if fit also want the sports mode only mah! Don't tell me fit this and use economy mode......

is there any applicable for non-drive by wire cars?
e.g: myvi / viva / kenari / kelisa??

Can this be use as to improve fuel consumption? If can, how much can save? better than vs?

I feel although Throttle controllers offer no power gain, however enhancing the throttle to achieve greater respond will improve lap times.

Imagine the time you need to depress 2/3 of the pedal & wait for your car to respond whereas with a throttle controller you needed only a fraction of the time to do that.
