we don't need tuning
Yeah, I mean, electronics are definitely responsible for making cars more reliable
I totally want electronic systems controlling valves
what could go wrong?
It's no different than your fuel injection being controlled by a Hall Effect sensor on the crank.
I don't think faulty fuel injection or crank sensors can wreck your engine
It's still mechanically connected, I believe. It's just the individual cylinders can be adjusted. The most that would happen in a failure is some pinging in a cylinder, which would throw a code and put you into limp mode.
Plus while it is electronically cintrolled, its not electric motors or some shit
Pneumatics
Think of it like being able to adjust the spring rate of your rockers
Your computer would have to be either pretty slow or pretty stupid for faulty freevalve to ruin the engine
if it fails and a valve is in the wrong position when the cylinder returns and it has no signal to adjust, the valve will stay in place and it's basically like what happens if a cam belt or chain stretches/snaps, your shit would be fucked
I don't think that's how it works
Besides, dont most modern engines die when that hapoens for that reasin?
the peak reliability of cars seems to have been 80s and 90s depending on manufacturer, electronics since have made cars less reliable, though there's some question whether the increased requirements in efficiency have also contributed to the lower reliability
Reason
It's still a non-interference engine like any other, but instead of ALL the cylinders being adjusted with VV-T, it's individual cylinders
The increased emissions requirements is most of it, i would say.
I doubt the freevalve engine is non interference
Considering yiu still have shit like, fir example, the million mile toyota tundra, cars are at worst just as reliable.
very few modern engines are able to be non interference because of efficiency requirements
I wouldnt call a modern fca car more reliable...
I'm not sure if any regular cars on sale are non interference actually
Well, it seems the conversation won't be fruitful and is just some more competitive pissing, so w/e

Most arguments about reliablity become that, really
There isnt a whole lot of hard data on car reliability. Best you have is iffy af surveys
well that's because reliability can often be highly subjective
owners and how they treat their vehicles contribute to failure rates
and it's very hard to adequately monitor that
but in general, the old hilux, a bunch of 80s and early 90s benzes, late 90s jap N/A 4cyls are all ridiculously reliable
like, terrifyingly so
but there's also basically nothing to actually go wrong on them
And there are engines, newer ones, where this remains the case
See the vortec 6
the newer vehicles are so loaded down with craptastic bullshit that tons of shit can just die
Toyota 4.0
Etc
Emissions is undoubtedly to blame for much of it
Easiest to see with the big truck diesels actually
