I had to do 20 miles in an E30 with no throttle cable once. I just wound out the idle stop so it did about 5000rpm unloaded.

I once had to be the gas pedal in my mom's 67 bug. It snapped off right at the pedal, so I just put a set of vice grips on it while my mom drove and I gave throttle as needed. Another fun time was snapping the clutch cable 30 miles from home and using the starter in first gear to get home. Luckily it had a brand new transmission with good synchros.

After the throttle cable snapped in my 71 super stranding me 30 minutes from home I started keeping a spare in the glovebox. Came in handy more times then I care to remember.

I really dislike DBW that gets in my way. Just do what I asked, you fuckhead car. There are only a few cases where I think it's awesome - it's great for helping with electronic stability / traction control (assuming non idiots designed it), and great for stuff like automatic rev matching for upshifts and downshifts, which appeals to me as an engineer, but not much as a driver. Amusingly none of this applies to 13"s car, seeing as it has like 9 wires in the entire thing and most of them are turn signals and the horn

I don't even have to compare old cars with carbies to DBW. There was a huge difference in throttle response between my EL falcon (EFI - Cable) and BA falcon (EFI - DBW)

I've never heard of anyone breaking a throttle cable on a Japanese car, even an 80s model with hundreds of thousands of kilometers and no one pro-actively replaces them.

Early 2000's bikes and some cars used a traditional cable and butterfly and a second electronic butterfly that would only open as fast as the engine could respond, acting like a constant velocity carb. Maybe it's something like that? Or maybe it's only purpose is to even out the input and improve mileage, I dunno. I have no beef with drive by wire throttles except for having to plan ahead .5 seconds when I want the gas to come on. I seriously doubt any of the systems out there now will be performing as well as a cable in 40 years time and that goes double for the finicky crap in my e60. Also when it does go I cant use a shoelace tied to the throttle and run through the quarter window to get me home drive around for a few days like in my old Sprite.

Mine's a diesel, so it's not like there's even a throttle body to gently caress about with.

I rented a U-haul recently (not a performance vehicle to be sure) that was a recent Chevy van model. I swear to God nothing happens for the first 1/4 of the pedal travel then all of a sudden WHEEEE it catches and you're off and running. Driving smoothly at low speed was all but impossible. I imagine it's an emissions/mileage thing for hamfists that just treat the throttle like a light switch but it's seriously annoying.

Psh, throttle cables and DBW. Clearly the correct answer is a throttle linkage that consists of a lever on the pedal and a rod going to the carburetor. Don't have to worry about your 1/8" rod breaking on your drive home. Why make it more complicated by using a cable?

I used to have this, it was p. cool but the pedal was held to the rod with a ball and socket joint and kept popping out if you weren't experienced with driving it.

Don't have to worry about your 1/8" rod breaking on your drive home. Why make it more complicated by using a cable? This is what I have on the C10. Dont even have a pedal, just the metal rod coming out of the firewall and connected to another rod to the carb, like a boss. I drove my first DBW car in years a couple weeks ago when I did the tbelt on that Audi and it sucked so bad. Took forever to respond and then when it did it held revs like it had a 500 lb flywheel, rev matching/etc sucked.

That sounds remarkably like a complex expensive electrical system emulating a simple cheap throttle cable, then. I say that as an embedded systems engineer in the midst of putting well over 40 microcontrollers and likely several million lines of firmware code (one of em runs Linux, or it'd be under half a million) on a car/plane. KISS principle still applies, especially on critical stuff like brakes, steering, and throttle.

Everyone knows the best throttle is having the cover off of your vans engine and driving with one hand on the wheel and one on the carb directly. Bonus points if you don't have a fuel pump and control rpm by the speed of your pour of gas out of a beer can.

cursedshitbox posted:You fuckers bitch about DBW, but you ain' lived till you drove DBA. (drive by air) Ah, the mk1 hillman imp. The gas pedal actuates a pump, that compresses air which controls a second pump at the Solex carburetor at the back of the car. A lovely idea, but the rubber hoses had a nasty habit of deteriorating and leaking, so you'd have to pump out the accelerator pedal if you wanted to keep up the revs. SO glad my imp is cable controlled.

Yeah, they're the original whole radial engine spins around the stationary crankshaft, uses as much oil as fuel, with lovely characteristics due to gyroscopic forces that you wouldn't want in an aircraft type of rotary.
