I read in another forum that two C14s on the same ride experienced the "FI" at the same time.
Not sure if it was the exact same time or just randomly on the same ride.
However, if at the same time, then I would conclude that it was caused by some sort of interference. Maybe Ted has twice the brain power and mentally caused this to happen. I believe Ted has zero brain power, so 2 x 0 brain power is still zero, so who knows.
I reread the owners manual looking for clues and it's not much help. The only clue if any is that it is related to the Fuel Injection fault message.
Reading up on fuel injectors I find that "The amount of fuel supplied to the engine is determined by the amount of time the fuel injector stays open. This is called the pulse width, and it is controlled by the ECU."
From my engineering electronic design days, I recall that electro-magnets are energy storage devices. They don't like changes in their stored magnetic fields. So maybe, Big K did not put shunting diodes across them injector electro-magnets. Maybe they did and are not exactly right. When their pulse power is switched off, the field collapses resulting in an energy spike in all frequencies. The diode is supposed to prevent that by providing a path to short out the EMF. Now, suppose at just the right moment, some stray RF gets in there and adds to the collapsing field, maybe stretching it out a tad and the ECU detects it and throws a fault. But, as what usually happens, we get pass the RF and all returns to normal rather quickly.
Owners manual says "FI" is for a hard fuel injector fault and should show some hard fault code associated with it, but none appears. So maybe, just maybe, it's a soft fault that resets itself after some rather quick on the fly diagnostic. I can see it happening. Our F18 fighter jets have fly by wire systems that do real time fault analysis while flying. They detect errors on the fly and may or may not produce hard or soft faults. I don't know if this is the case or not for our C14s, but I would like to think so. It would explain the "FI" going away after a soft fault being cleared.
Who knows. Big K doesn't tell us everything. It would be nice to talk to the software engineers who cobbled up the system.
Then again...there is Ted...
