In Zilla's case, the odds are stacked against him, which is why the nay-sayers have an inordinate amount of ammunition. It's a VERY difficult project for an individual to undertake on a limited budget. Even if he DOES get it to work, there will ALWAYS be something wrong with it, right? I think people are missing the point that this is for a college project, and not reinventing the wheel.
I've donated to the project simply because I give someone credit for trying something. I couldn't care less whether it works or doesn't. It won't affect me personally whether it works or not, so I guess that's the reason I never felt the need to jump on one of the bandwagons. Do I personally think it's going to work? Eventually, yes, I do. Do I think it will make more power, and be more reliable than a carburetor setup? No, and no; but I'm also not going to fault the guy for doing something like this for a university project.
I seem to think that there's a reason new 4 strokes coming out are going to fuel injection. It's probably not "just because". What the exact reasons are, I don't know.
What I DO know, is that on EFI systems with a MAP sensor, and an IAT sensor, barometric pressure and air temperature are automatically detected and the fuel mixture is automatically adjusted to compensate once a baseline is set in the ECU/ECM. Thinking about it logically, I personally see the benefit of a system that automatically adjusts fuel mixture for the appropriate barometric pressure and temperature. You start out at the bottom of a mountain, and ride for 2-3 hours up a trail, climbing 3500-4500 feet. You're not going to stop in the middle of your ride and re-jet, are you? Then stop and re-jet on your way back down the mountain? Seems to me like in a situation such as this, a system that automatically compensates is the best answer. I don't believe a system could be manufactured cost effectively for EVERYONE to be able to buy it, but, if your riding area is a mountain and you have issues with jetting, what else can you do that is automatic that you don't have to constantly think about? Or what about the guys who live/ride in the area mountains in California, Arizona, and Nevada that may ride 50% of the time in their mountain community, but want to jump in the truck one weekend and head to glamis? Gotta re-jet. With an EFI system it would automatically adjust to temperature and elevation.
Why anyone would be AGAINST something like this, is bewildering to me. Other than the fact that zilla is kind of a homo and it's easier to play the odds and shit on someone than give them credit for taking it upon themselves to try something that one of us wouldn't undertake ourselves.
All (or, mostly all) of us drive fuel injected cars. I wonder why that is? Because, I mean, carburetors work, right? and worked great? Maybe EFI is on cars for emissions purposes... perhaps, but are our heads so far up our asses that we aren't willing to admit that one day emissions regulations WILL trickle down to ATV's? I mean, fuck, they're requiring lawnmowers to pass certain emissions standards. It's going to happen sooner or later.
