Re: Ford 60 pin connector breakout board

@firebat45 I like your way of saying hello. Good to see the contribution.

If you have any questions about KICAD, feel free to ask. I'd be happy to give you some pointers etc. I find that learning the keyboard shortcuts is really helpful.

Re: EFI for small engines

Hmmm, the better half would probably be happier with me if I made this one work. It hasn't started for years, but has been dry and it used to work, so it should now. It has some carb problem last time it ran. Basically I had to run it as the floats would overflow if it was not running. It's already ...

Re: EFI for small engines

I lack motivation as my 15 year old snow blower starts on the 2nd pull in the dead of winter. It's reliable simple, and just plain works. I see little advantage of adding many new components that lower the MTBF. So I'm lacking motivation. I'm glad to hear you have a solution, it's good to hear peopl...

I don't think our diy quality controls match Ford's quality controls. There are many difficult situations to deal with. I suggest doing what was and still is the dominant technology for TPS sensors.

Re: EFI for small engines

Why would I make a dyno which does not preform a useful function, when I could make a dyno that also has a useful function? I prefer an electrical load, as it allows variable loads, which can be adjusted rapidly, and can get the engine into loads that are harder to obtain under different methods. Su...

Sounds like adapter PCB to MRE would be a good first start. The breakout could be expanded to include other features while you could still use the same MRE.

Re: EFI for small engines

The injectors, coils, etc are minimal watts. The generator is just to make a useful development platform which can have various loads added to it. The 12V is for the inverter generator, not for fuel injection. Yes brackets like that would be great. I see amazon link you provided also notes commonly ...

Re: EFI for small engines

I have snow blower motor and 10a 120v inverter. So I guess I'm looking for 1200 Watts from drive shaft at 3krpm. How do I generate 1200 Watts of 12v at 3krpm? I guess price should be under $500 as I can but one for $500. A truck alternator is probably good but I need to mount it some how.

Re: EFI for small engines

50W is too small. For a generator you need more like 1500W to be useful. I like the idea, but the magnet and coils are too small.

Re: EFI for small engines

I suggest you try just the sensor. Make 10 pcb's and connect then to the TB. Then simple read the Position out of them. You will then see the issues and you will then see why they are not more commonly used.

Re: EFI for small engines

I saw the Stihl links above. I recall they did a version of direct injection. Direct into the cyl, but not while under pressure. The 2 stroke made this kind of interesting, as it keeps the fuel/oil out of the crank case. A design would require knowledge of what TB and exactly what injector it is to ...

Re: microRusEfi

So 60C - 20C, is a 40C rise when PCB is naked. AEQ ambient is 85C, so 85C + 40C is 125C, which I believe is above the desired max temperature for the naked 0.4.7 board. I generally attempt to design with a PCB temp below 105C as there are some MFG's that have PCB's which are only rated for 105C. It ...

Both of this solution non-programable and require battery. You need to buy from those company 1000+ articles to get adopted for you engines. How do you EFI with no battery?
