hi guys, just wondering if we can convert any new cars into using throttle cable, or new car still uses t.cable or equivalent replacement?
Modern car that still uses throttle cable, or any equivalent replacement?

oh..how i wish theres even 1 car using cable and NOT drive by wire..
i would buy it anytime |

The ECU determines the throttle opening based on accelerator pedal position and inputs from other engine sensors. ----- so basically, the throttle actuation has two type. the classic : http://chevythunder.com/2010%20project%20t...20cable%202.jpg and the modern actuation = throttle body http://www.firstfives.org/faq/throttle/Throttle_plate.jpg so its actually whether your car throttle is using throttle sensor (electronic throttle) or not la. If it uses electronic, it slows down response time. I know old fashioned kelisa doesnt have throttle sensor. |

to make things simple, if your car uses throttle sensor, it means electronic throttle. It sure lags your response time.
If no sensor means its "fun time". All your mercedes benz, BMW, Audi confirm has throttle sensor means it is slow when driver accelerate but because of engine power, it catches up later. Car like Kelisa, wira or old car that has no sensor = once u accelerate puhhh.. u run like horse. Please list down any modern cars that use NO throttle sensor, then I m happy with my next purchase. |

Drive by wire systems has it's merits compared to traditional mechanical systems... it came to automobiles after digital controls are proven to be advantageous in fighter jets like the F22 Raptors...
Like what Bubble Ring says... there are many reasons to why drive by wire is implemented from the ability to manipulate driving characteristics to safety and control systems that are in place... There are reasons why digital throttle are in place as this makes it easier for manufacturers to intervene in between the car and driver for various multiple reasons.. there is no reason why a digital throttle cannot be made to act and have the linearity as if it was a mechanical system... QUOTE(Selectt @ Jul 5 2014, 07:48 PM) to make things simple, if your car uses throttle sensor, it means electronic throttle. It sure lags your response time. 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... If no sensor means its "fun time". All your mercedes benz, BMW, Audi confirm has throttle sensor means it is slow when driver accelerate but because of engine power, it catches up later. Car like Kelisa, wira or old car that has no sensor = once u accelerate puhhh.. u run like horse. Please list down any modern cars that use NO throttle sensor, then I m happy with my next purchase. 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... QUOTE(Selectt @ Jul 5 2014, 10:20 PM) good that they improved the electronic throttle. Have driven few hondas and toyota.. all have throttle lag. 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...i think each manufacturers has different setting producing different result. like mr_alien said those lux vehicle has fast response time. while not for some honda and toyota? need to drive to compare haha 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...

Following are not so common implementation of drive-by-wire throttle system:
1) Launch control. Rregulating throttle and optimum engine output to prevent traction loss. 2) Rev match shifting. Regulating engine speed to match the speed of transmission input shaft. 3) Speeding teenage driver? Here's the parental control solution (speed limiter). 4) F1 pit lane speed limiter. QUOTE Exceeding the Pit Lane Speed Limit (fromseason 2014 - 60kph in practice and qualifying, 80kph during the race) results in a hefty fine during practice and qualifying ($250 per kph above the limit; more for a second offence), and a Stop-Go penalty during the race. It did not take long for the drivers to demand a technical solution to prevent speeding in the Pit Lane. All cars are fitted with a button on the steering wheel that imposes a speed limit to the car. It can only operate in 1st, 2nd and 3rd gears, must be selected and de-selected by the driver only, and only used in the Pit Lane - these regulations are to ensure that it is not used on the track as a crude traction control system. Pressing the button changes the engine rev-limit, according to the gear selected and the limit in force at the time. Drivers must remember to press it before crossing the pit entry line, as it does not instantly slow the car to the correct speed, as some drivers think! 5) Allow F1 Race Engineer to program song. Above examples demonstrated the many possibilities of servo motor driven throttle butterfly valve and it's impossible to implement with traditional mechanical cable driven type. The drive-by-wire throttle system doesn't work alone. It work and communicate with other system. |

There also already steer-by-wire on production cars.
Those who complain about numb electric power steering.....prepare to complain summore |
