Is it possible to retrofit a used "computer" vehicle and remove all digital tech to make it electromechanical again, where the owner has complete control of what they purchased?
"All" digital tech?
I don't think most people realize that any powertrain new enough to even have fuel injection is going to be a "computer vehicle" in some capacity. How are you with carburetors?
That's not really true. The first fuel injection systems were mechanical. The first one of those used in a gasoline-powered 4-stroke car engine was in 1955. Bosch mechanical FI systems were common in higher-end European cars from then on. Digital electronic fuel injection controllers weren't common until the 1980s, though there were some EFI systems controlled by what were essentially crude analog computers as far back as the late 1950s. I know that Volvo had such a system in the late 60s since I owned one. It was extremely reliable.
I'm great at carburetors. Especially the Holley 4 barrel carb. Trial and error made me good at it. I had the freedom to try. We no longer have that. So, yes, all digital tech. Just electromechanical so we can save huge amounts of dollars by not getting involved in the "repair industry". Transmissions are a different beast but if all the "Chilton's'" auto repair manuals have not been secreted away and completely destroyed then I at least have a fighting chance to figure it out.
