One possible comparison column to add might be “upgradable firmware/software?” or “Software-free?”
It’s a brave new world out there, and the knee-jerk expectation might be that programmability/upgradability would be an obvious positive. Even speaking as a very broadly tech-positive person, I’m conflicted when it comes to this subject. I personally draw the line on software where basic operation of the engine is concerned.
Although I do respect the advantages of programmability and the objectives of products offered by SDS and others, I elected to install LightSpeed Plasma III’s for their software-free, hardwired, discreet-logic circuitry. I’m forgoing the advantages of most available EFI systems for the same reason.
This is an entirely personal choice, perhaps over-cautious in today’s world, but I’ve got to go with my own intuition. My concern is two-fold. First, potential software or firmware glitches can simultaneously disable both elements in a redundant system. Second, such glitches can be insidiously difficult to trigger via standard debugging procedures, thus making all users in a small world like ours default guinea-pigs.
I’m not trying to talk anyone else out of installing software-based essential systems here, but it would be good info to have in the chart for those who share my concern.
I WOULD suggest avoiding simultaneous firmware/software alterations in both elements of redundant systems whenever possible and for as long as possible, though!- Otis
