those are all drive by wire la
those modern engine
even ancient tech campro engine all already drive by wire
hence drive by wire lag happens

no.mechanical cable..

I know there's electronic fuel injection control. But i don't know that throttle in modern car don't have mechanical linkage. You mean my Viva 850 got electronic throttle control la?

this
and those MB, BMW and audi surely have electronic throttle sensor
but it feels like none because their throttle response is faster
i've revved and drove an audi before...it really feels like there isn't any DBW delay
the response is so fast
or should i say sensitive

too sad to say it went down the same road as carburetors

i guess you are pretty much getting things wrong here... digital throttle does not cause delay in throttle response... it is the deliberation of the manufacturer or a poor design that causes it... there is no doubt that electrical signals can travel through a sensor and wire as fast as the cable can react to the input by your foot... the only problem in the entire setup could only be the actuator motor that control the throttle plate not being able to turn in response fast enough hence a design factor...

and there is also reasons that manufacturers want to control over the throttle movements for reasons like prevent jerkiness in case the driver decided to feed too much throttle all of a sudden... the last batches of 2JZ VVTi motors actually introduced digital throttle which dampens throttle inputs i think by gear selection which in which way you look at it, might give it a smoother feel or safer as there would not be so much possibility of sending a surge of power to the driven wheels...

on the other hand, drive by wire systems in some cars (proton iafm manual) helps the driver to compensate for the lack of throttle (to a certain extend) if the engine is about to stall due to things like clutch not being released smoothly...

then on another side of things... digital throttle can be used to tune how the car reacts in different driving conditions like how most european marques like to add a "sport" mode to their cars...this can help sharpen up the throttle for spirited driving while turning it off will dull the throttle response down to make the car easier to drive in city driving...

if you are saying that DBW is the entire cause of all the conundrums... then you are indirectly saying that this proven technology is also a wrong direction in development in many other applications among things like fighter jets and the various robotics that are used in the medical / surgical field that might one day save your life...

the same reason why fly by wire exists in a F22 Raptor is because the design of the F22 Raptor is aerodynamically unstable which makes it impossible for a human being to fly the plane by itself and still focus on combat maneuvers.. this is why fly by wire is developed to be the intermediary between the pilot and the plane so that the pilot can tell the plane what it intends to get the plane to do by the electronics controls and the computer to command and make further decision on how to react to get the plane to do what the pilot wants it to do...

the same can be applied to cars of today if you see it that way... many other reasons can exists and it does not have to do with the car and yourself directly as it can be something as unrelated as emissions control or anything the engineers can think up which digital control systems can provide and be of assistance in the bigger picture...
many cars have throttle lag and especially worst.. throttle dampening in the first gear... if you are still driving your FD2R... consider investing in a hondata flash pro and you can play around with the "Target Throttle Plate" settings which will reveal a lot to you in terms of how the stock honda mapping is programmed... putting 50% throttle sometimes does not mean a 50% throttle plate opening on the throttle body for various reasons...

and there is reasons for throttle dampening to be applied in 1st gear as some cars might be a handful for some people in 1st gear which can be dangerous sometimes... you wouldn't want your GF to be ramming down the parking ticketing machine because she could not compensate the throttle properly for the incline where the ticketing machine is placed or your mother got startled by the amount of acceleration in 1st gear driving your car compared to her puny 1.0l city slugger....

as i say... in the bigger picture.. there is merits in such system being introduced... they can't make the car less sensible and go backwards just simply because you do not like it... that being said, there are always ways to get around it via aftermarket upgrades \ hacks and whatnot unless it is physically impossible to do so from a mechanical perspective...

unfortunately, the world revolves around TS... so he jus wants what he wants one way or the other... Honda / Toyota / Suzuki / Subaru / Kia / Hyundai / Ferrari / BMW / Merc / VW and who knows what will all have to do design their cars according to TS's needs if they intend to get his business...

very apparent that no argument is going to be valid from the start of the thread...

There's a reason why some cars come with different modes. Can set it to be responsive, can set it to be comfortable and fuel saving, depending on how you want it at this moment. Maybe the TS has to buy one of those cars?

Do you know why?

Fyi, TS has been poisoned by Scotty Kilmer video about the drive-by-wire throttle system.
You can check out this thread.

Personally, I like Scotty Kilmer's repair videos. Short, simple and funny.
Anyhow, I feel that guy quite anti-technology and always praise his ancient tech Toyota Celica.
