jonr, That's a good DI read about a modified motorcycle DI. Here are some of my thoughts. They used a .1ohm sense resistor. That itself creates some really interesting LRC characteristics. For example, the injector being supplied with a 70V supply could very likely see more than 300V at the injector...

I'm playing with small engines. So if it's possible, the question is, what automotive injector am I using on my small engine. That I don't know yet, as it's not in the realm of possibility for me. If there were software to back it, I'd be interested in giving it a try. GDI would fit in well with the...

I guess I don't see the significant difference between diesel/DI and gas/MI. While I understand your code is currently developed for manifold injection, I see many parts as usable for both types of systems. You have kept quite a bit of flexibility under the hood after all. In terms of physical hardw...

Oh, my. Fred forgets the diesel folks that have stopped by. http://forum.diyefi.org/viewtopic.php?f=42&t=872&start=0&hilit=common+rail I know several folks that have taken a diesel off the shelf truck, changed the injectors, changed the pistons, found a turbo mounted under the wing of a ...

Per ravage thread, lets add this to the list.

I like the end of the test video, however it would have been better if he tossed in a bit of gas and a match

Best contribute is probably to help Fred with code.

About the math, I see 360 deg per rotation with infamous .1 degree accuracy. The key is to figure out if that's on board or not, ect. The DMA clocking is based on the RPM input, so it clocks per RPM, not per XTAL.

Yes the idea of a swap-able brain is one of the motivators behind DFH. At the moment the best developed brain is the TA card and Fred's code, however you are correct that other brains could be installed. One idea I like about most ARM's is that you can DMA rake a piece of memory across the outputs, ...

I also like ARM's, but I'm not that good with software, and I don't have enough time to try it from scratch on my own. I believe one key issue your above noted board will have is the number of IO. Also I'm not aware of an ARM based ECU or EMS, so software for such an approach is limited and much nee...

Congrats Congrats
