Anyone paying attention has known this from day one. The more you rely on the tech in a vehicle, the more you’re enslaved by it.
Incidentally, I predict printable step by step instructions on decoupling technical components from modern ICEs will become popular. I’ve already started investigating it for my 2017 F150
That’s gonna be tough to do, when there are so many sensors for just the timing of fuel injection and firing. If automatic, there’s clutches that rely on the computer.
More power to ya, but it sounds like the new stuff is beyond converting to old school. I even feel that way about my 07 highlander.
