I'm thinking .....:?...OHHHHH NOOOOOOOOO not those carbs acting up again.:?.....
anyone here done an efi swap ? TBI or MPFI ? do I have to be the first? its seems that getting carb parts is harder each time, and I live in a digital world. I don't get to play with points and such silly things either. I efi'd my 78 Bronco just 'cause I hate carbs too.... Anyone tried and succeded ? failed ?:baffled: what do I need to watch out for ?
Rick.

You're not the first to think of it but you could be the first to actually do it. Go for it man.

It has been discussed many many times. There are several with superchargers but none that I know of with EFI. Mooseheadm5 and Tausinieraider (sp?) over on the Nekid Board have been talking about it for a while but I do not think either is near the install phase yet.

it could be done, but you would spend like 5X times what your bike is worth. so i would sell it and get a 1200 sei or ltd, those two are fuel injected. OR.. get a 1800 xD would be cheaper.

I can't see that happening.... I love my gl1100A, I have enough stuff here to do either the mpfi or TBI with stuff on my shelves, and its all paid for already. I'm a journeyman mechanic by trade and I love do do things that just haven't been tackled yet. I own welders and plasma cutters and presses and all kinds of fabrication tools. I would however like some positive information on what has been tried and how it could have worked better . It's all here ..skills, tools, parts and curiousity. Positive ideas and suggestions are a plus. If it did cost me 5X what you think my bike is worth, I'd still feel that mine is cooler than yours :p

Motorcycle success stories.

Don't see the 1100, but there's some pretty good ideas on the success page.


1500 specific, below.

I used the neder language, and used Google to convert it to English, somehow, awhile back, and now I forgot how I did it. The English page is missing the bottom portion, for some reason. Search this Saunders site, for 1500 fuel injection, and you'll probably find the link I had for the full English. I'm on my way out, so don't have time to search.

EFI'ing a 78 Bronco seems like a high school shop project. I would hope it's simple considering most EFIs are designed for auto apps. But an old 1100? Sounds like a waste of time but since you're a journeyman mechanic by trade and love do do things that just haven't been tackled yet I would think you'd be plasma cutting, pressing and welding that EFI'ed 78 Bronco engine into that 1100a frame cause that ain't been tackled yet!
PS: I'm thinking 10 or 20x what an 1100 is worth

nope, not simple with a mpfi setup .......theres not enough time in a semester to do it . Everything from intank to exhaust is different. Gold WIng can't be much different, you need all the same inputs for an 1100 as a 7500. all inputs go to computer that controls output. There are a few different styles ..........some use a mass air flow sensor, some don't, some have injectors at each cylinder that batch fire, some fire sequentially, some use central FI etc. An O2 sensor bung is very easily added to any exhaust for input to the computer for tuning purposes. Electric fuel pump for pressure. It's all doable, only difficult part that even needs to be fabbed is the airbox for throttle plates ( or throttle body). I guess since nobodys done it here, and I live in a climate where the bike is parked for the next 5 or 6 months, I'll have to try and make time to just get'er done. the 7.5L in the Bronco uses more fuel warming up than the 1100 uses drving across town, so that idea ( while certainly cool in theory ) is going out the window for now.

I have actually thought about this quite a lot. It has gone on the back burner since I sold the 1100 I was going to try it on. My thought was to use the throttle body injection off an old Honda civic or a 4 cyl GM car. The only thing I haven't studied on how to do is where to get the pulse for the engine rpm. All else would be pretty straight forward.

I'm in the process of fitting megasquirt injection to my 1500 the only difficult bit is mounting the injectors and figuring out the wiring and programming, I've chosen to let the megasquirt unit do the spark and th
e fuelling.

Cool, a 1500 fuel injection.

anarchychaos, can you start a new post. I am sure many will be interested and would have many questions.
