What do you think about drive by wire?

No thanks, I'll keep my cable.
>b-b-b-but it simplifies the idle valve!
If I ever go standalone ECU I will build myself a choke cable to manually bump my cable throttle wheel open for cold starts.

Are you retarded? It's night and day in difference. With a cable your foot opens the throttle right then and there and with drive by wire you foot input is merely a suggestion to the ECU. You have to put the ECU into sport or sharp mode, if it even allows for that, just to have normal throttle operation. The default state is to ignore driver input and gradually open the throttle to sluggishly take off from a stop for muh empeegees.

when you make a car this electrified, you might as well make it work like a diesel-electric locomotive and decouple the entire engine from the wheels, using electric motors instead, with the engine acting as a generator

Funniest part is when you jump from a laggy drive by wire to cable throttle body you have to reel back in your aggressive throttle inputs.

Just like wireless mice, the technology has evolved enough to be superior if done right but most manufacturers are too cheap to put in the work.

It's fine if done right, but I very much prefer the pedal feel of a cable throttle. I find many DBW pedal setups way too light and "floaty", *especially* when it comes to the brake pedal. When I occasionally have to move someone's new car, I will always end up nearly planting myself through the windshield when trying to come to a gentle stop.

my 05 Civic has a cable which makes the response really sharp, giving the relatively weak engine some pep. My 08 Rabbit has a dbw which makes the relatively strong engine feel lazy.

I'll DBW swap and NA ITB build my 2JZ. With a Link ECU and fully programmable pedal map, I can make it feel however I want, and be as direct as I want. Gives me idle-up and cruise-control for free.

>they bite different in every car
Most mechanically linked boosted brakes feel quite similar, with a few exceptions, but the difference in brake by wire to mechanical is comically noticeable. It's easy to get used to once you're aware of it, but there's very little progression to a brake by wire system when compared to a mechanical setup, and the pedal doesn't stiffen up like a mechanical setup, so you're expecting some sort of feedback that just never comes. Not until the car lurches to a stop, anyway.

>also most DBW is only for the throttle
Unless they're hybrid or electric, as with the modern cars I've had the displeasure of moving or driving.

I had the opposite. My cable operated cars were somewhat lazy, where as my DBW car was violently sharp. It's all down to mapping.

For factory ECUs maybe. With a Haltech you can make it behave like a cable/carbie throttle. The throttle lag is purely there as an emissions reduction mesure fromt the OEMs. Not all drive by wires need to be like that.

In stock form, in a lot of cars, fucking awful.
Yes, it simplifies the idle circuitry. Yes, it smooths your inputs for better empeegees. It also means you need to fucking floor the damn thing if you want it to actually give you some semblance of power, and makes blipping the throttle on downshifts needlessly difficult.

why would you need to? fuel priming, crank fueling, and timing can accomplish the same thing for cold starts. IAC tables take over when up to certain temp.

Firstly we don't talk about the NC.
Secondly it's an NA
Thirdly Fits didn't even exist before 00 and mine is a cable. You probably have a turd gen or are thinking of them.

It kinda sucks. My previous cars (years ago) were all normal and I miss the progressive pedal action where the solenoid or whatever opens a little bit more when you push the pedal more.
With my newish drive by wire car - a little throttle pedal gooses is too hard, and then 20-30% of the way in the solenoid is fully open and there's no difference between half pedal down and pedal fully down - wasting the pedal and hurting my feet
you really notice it if you have to drive extra slow behind someone who is going below the speed limit - hurts the fuck out of my feet

Nothing wrong with TBW, it's just most cars have terrible implementations on purpose for emissions reasons.
Just look at motorcycles, most new sport bikes have TBW and also have phenomenal throttle response

everything digital has lag vs analog. I have some tuning done to my car that has dbw throttle. Its alot better than factory but still doesnt respond as well as cable would. there are time when im at like 3/4 throttle,let off to shift and the revs climb 500 rpm.

Well it does, DBW makes the IACV obsolete, as well as any idle-up valve control and any A/C idle control, which are both non-trivial mechanical parts. In addition, it makes any cruise control actuator obsolete (my '92 Camry has a milk carton sized electromechanical module for cruise control). Also allows for limp-mode engine protection.

DBW throttle bodies are actuator and TPS on the same wire, so it doesn't even make the harness more complicated than it was with any older EFI engined cars.

Like others have already said it all comes down to the programming, assuming were not talking about carbs. I've driven lots of cable actuated engines that had terrible throttle responses. I've driven large displacement diesels with e-throttles that were insanely responsive. Just lightly tapping the pedal would make the tach needle twitch. While most modern e-throttles aren't programmed to have a 1:1 input vs output they can definitely be programmed to have that if you want.
