How is the injector controlled when to spray? Every fuel injection system ive messed with used an on off trigger on the injector itself or has been rocker driven this is def a new design to me and im super excited to see it in action.
Here's my article covering the basics of how my injection timing works on NEFI and my initial tests way back in 2015. I'm sure it's not an original way to handle timing, it's probably the most obvious way to do it on an 8-bit AVR micro. It's simple, fast, and accurate.
NanoEFI - Proof of Concept: Tests successful!
I don't intend to incorporate CAN until support for newer more technologically complex vehicles starts making it a requirement. Interfacing with ABS modules, OEM gauages, etc. As far as diagnostics, with Wi-Fi wireless capability directly on the ECU, anyt wired troubleshooting tool becomes obsolete. Even burning firmware updates will be wireless by internet, "over the air" with no physical connection.
A physical dash that uses the wireless connection is something I've considered. But the fact is, if I take that on myself it will be years before I can finish it (look at how long it's taken to get through with A-Arm's recently, and I've been making those for years).
I believe cool add-ons like this would be best developed as community projects. NanoEFI draws a lot of guys from the maker crowd, since development for the first couple of years was on the Arduino platform. Though I want to protect my core code, I plan to encourage modifying the system through an open API for added fun and customization.
AHHH I gotcha maybe I am crazy but in a simpler fashion how will the injector be fired IE you mean pulse width modulated pump so I gather that would mean the injector would only cycle as the pump does? my question is how does the injector close and re open as to not loose prime in a sense. I get that there would be no return fuel line so aspects of a dry start or air to injector is my concerns I would think that the injector would have to be electronic in this aspect.
All of this begins with an idea when I was speaking of a CAN network im thinking way advanced and maybe a future add on for abilities of troubleshooting like a simulated diag aspect of compression test and such I know this is far advanced but I can dream right I know I use CAN networks on a far extreme levels of monitoring engine operations and it is helpful but as you stated this a huge development and would take years of engineering code C++ to dial in. single cylinder engines well they are single no need to cyl cut outs and such but the ability to expand this aspect is cool to think about.
