Default Gas-pedal modulation: adjustable ?

After third service, the gas-pedal response of my Baleno feels more
sluggish than before for some reason (if I'm not imagining things)!
What could have caused this? I wonder if it is somehow possible to
adjust the gas-pedal modulation! I always thought each car had its own
preset response. -- It is not that I can't live with the current feel
of how the car runs, -- in all probability I'd have accepted it the way
it is now, had the car behaved the same way even before the service.

I don't much like a feather-touch gas-pedal response either; -- I remember
hating it on a Toyota Camry, and being told that it was typical of Japanese
cars, and the reason why ladies prefered those to American cars !
I couldn't relate because of a lack of experience with Japanese cars.

It'd be nice to be enlightened in this regard by experienced members. Thanks.

Its just " PLAY" in the pedal, You can get the pedal adjusted as per your need...The thing goes lose slightly over a long period of time, as full weight of the foot and constant depression....It will take you 10 min to get this adjusted...!

Pardon my ignorance, but I thought "play" meant the inconsequential
travel of the pedal *before* the throttle valve actually engages. My
query was, whether it is possible to adjust the actual length of travel
of the pedal required for zero-to-full opening of the throttle valve.
If that is what you meant by "play", then it makes sense now, and I
think for some reason the pedal travel was adjusted for more total travel,
so I actually need a longer foot travel now (not more pressure) to
achieve the same acceleration (thus a seemingly lesser "pick-up").
Such adjustability would also suggest being able to change the feel
of the "pick-up" afforded by the same engine, would it not ?

Come to think of it, there could be a whole host of parameters that could
be adjusted in the ECU (e.g. the lag in actual fuel-injection from opening of
the throttle valve, the richness of the fuel-air mixture and so on) to give a
similar change in the feel. Are such things typically fiddled with at the service?

Hi,

Try adjusting the throttle position sensor mounting position. There is an option to rotate it back and forth. Can control to a degree what throttle position the ECU sees ... You should get the "feel" back with this .

Thanks for the tip. I'll keep this in mind when going back to the service station.
