fuel injection in 500's ?
cbrfrenzie:
You're making me think now!!! There is actually an extra driver on the board that could be "possibly" used to control a servo for RPM, MAP, TPS based KIPS control :-P

Very true... with this controller you can choose an RPM input, up to 2 different 0-5V analog inputs, and/or use the on-board 2 BAR absolute pressure sensor to determine the injected fuel quantity. We have an injector flow bench at work too, so finding the exact injector specs makes controlling them that much more accurate.
Last thing is to power a fuel pump, injector(s) and controller, run a fuel line and install some kind of fuel pressure regulator. I'm sure a billet intake boot with injector boss would be pretty easy to fabricate. Aimed right at the center of the reed tips... :evil:

Well, if you wanna play around with this, send me a PM and we can get you something for next to nothing... :-D
I do know that injector placement is KEY is the 2 stroke naturally aspirated application. We never messed with case injection, but that may be easier to adapt?? I haven't walked out to the garage to check out the cases. Not only placement, but angle as well. They make different injectors, and the 4 or 12 hole pintle models work the very best. I can give you some injectors we have used in past applications. I'll run the math tomorrow and see how many CC's we need to FULLY support the engine with zero fuel from the carb (worse case scenario I guess).
What carb are you running Motorrad?
Motorrad:
44 lectron
Best way I see. Is 2 injectors aimed to cross paths just past center of reed tips
cbrfrenzie:
That's a good call there. You could do one of smaller CC's closer for the low range and fine fueling adjustments and use a larger one further back for the upper mid and top end. Many possibilities once the system is actually on the machine! :-D
