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

Still relevant.

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

But me like the idea of standalone tongue.gif

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

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.

how much is this ETC thing for gen2 campro batch 2?
is it plug and play?or need to cut/splice wires here and there?
where can i find the product link?

This is a technical sharing topic, not a sales topic.
Ask for it else where.

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

as explained, you can change the throttle pulley if you can find someone making it.

How much heavier will the pedal feel with smaller throttle pulley? negligible?

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