I've started designing an EFI kit for our beloved GS. I would say I am around 20% done right now; still planning and prototyping some subroutines on the microcontroller ironing out how to do what needs to be done.
My objectives with the kit are as follows:
Total cost <$250 for everything::: (most of that is the damn fuel pump...)
Bolt on::: retaining carb functionality for those who want double reliability or cant afford to tweak (work bike etc)
Tuned like a 3 stage carb with a screwdriver (no need for an extra laptop suctioned to the gastank while you tune it and ride around)
Simple: 2 external sensor connections.
Also:
I was thinking about doing an ignition advancer but it wouldn't be as cheap as the mod available.

A picture I took this morning to prove I'm really working on it :flipoff: http://i150.photobucket.com/albums/s95/ddphoc/uctesting.jpg
And to those who are curious. Its being programmed in C on an Atmel AVR 8 bit microcontroller.
woot !
if it works i'd buy it to go EFI
Sounds sweet. Keep us posted with MORE PICS! :icon_mrgreen: Oo and updates.. :icon_mrgreen:
sounds pretty awesome, I am excited to see how it works when you get done!
subscribed
ya i would buy and EFI kit.
interested
:thumb: Awesome. Interested. Keep us posted.
:bowdown: :bowdown: :bowdown:
holy crap, that would be AMAZING. I always thought that there was a huge hole in the motorcycle market for a EFI kit, after you get the gs500 kit done, you should work on a universal kit for everything. I'll bet you could sell a TON of them if you could get it working well/reliable
Yeah, sign me up! :o
count me in. sounds great!!
Ok when y'all fit the new, super duper, jeffd invented EFI ... like just seconds before you kick that carb to the curb ... remember that ... I'd pay like 30 cents for them ... shipped ... with a 4 party post dated check made out in Iceland kroner ... good deal ... OK ... yea ...
Cool.
Buddha.
Oh no :o not EFI, that's gonna put Buddha out of business............... just kidding Buddha :icon_mrgreen:
Good luck JeffD :thumb:
I'm interested!
$250 sounds like a bargin. I paid $350AU just for my ecu when I set mine up.
Thats rediculously awesome. What would be even awesomer is if there was some way to add fuel mapping for boost... yeah just a thought......seriously though.
Just a thought, but it it can be tuned over USB. From a linux system. It would make me want one 10 times as much cause then I could use my n810(handheld computer) to tune things.
That's interesting. I'd love to hear more...

dont fret buddha ill still buy your jet kits
Dude ... its $250 for this EFI ... and 20 bucks for a jet kit. I can get carbs to run as well ... the problem is ... many people cannot. I figure I'd start to see a lot of hacked up GS'es in the near future where they tried to EFI and they broke somehitng ...
Cool.
Buddha.
Hey, does it run off of tps, map sensor, or oxygen sensor?
Oh man thatd be awesome! Will it be chokeless or will a choke still be required?
Got a little more buzz than I thought it was going to get! And no my plan is not to put buddah out of business; plenty of people will still stick with carbs. I just thought it would be cool to get a bunch of GS's on EFI easier than it is now; and heck its been fun researching and building.
And to answer a few questions:
No usb programming: The idea is to make it 'garage' tunable so anyone with a screwdriver can tune it.(I am using linux to program it if that counts :thumb:)
Yes there is a TPS
I plan on making the PCB "expandable" too, to be able to add whatever in the future. (or custom apps)
Haven't decided on a 'choke' yet ($2 switch or have a temp sensor and automate it....man vs machine)
From the looks of it the airbox will have to be replaced; a k&n lunchbox will fit the bill (and only $30)
The chip can actually be reprogrammed via 6 pin terminal for firmware upgrades (but not intended for tuning).
Big hurdles ahead:
Fuel Pump
Fuel Regulator
Fuel Rail/injector layout
You gota trust me that I'm trying to find the least expensive parts to build it....the auto industry well...stinks. For example, I've been searching for a pump/regulator combo for around 40-45psi simple right? no...Almost everywhere I search they have to have a 'specific vehicle'...I dont care what it goes on, I just want a pump. OR the damn things are inexpensive but designed for HUGE engines...and forget motorcycle fuel pumps. OEM pumps run $250+.... Seems like I've spent 80% of my time just trying to find a pump/regulator at a decent price. I think I found a pump/reg but just those are half the cost...
I should be ordering hardware soon to start building a prototype while I keep working on the program.
-Jeff :cheers:
Tee hee ... when the people who suggest that the bikes burnt its valves due to hot oil get their hands on this, I am going to get a lot of bikes that dont run ... teeeee heeee ... buy em cheap, then buy carbs cheap, hijack the injectors, fit it on my GS and sell it all for high $$$ ... teeeee heeeeeee ...
Either that ... or ...
These work so well everyone converts to it, and they need better wheels and forks and braces etc to handle the power ... and I make those and make a killing. Win win ... booya.
Cool.
Buddha.
man if you can get that thing runnin right ill be first in line to get one
Oh okay, screwdriver tuneable, thats cool by me. I just didn't want to have to hook it up to my windows box to do anything with it :)
As for the choke I like the idea of a switch better than an automated sensor. I don't trust sensors. (This coming from the guy that wants to rip out his car's entire dash and replace it with a car PC system hooked into the ODB2 port.)
do it with a temperature sensor, it would aid driveablility and make it easier to start and run
WAY COOL!!!
I want one!
Maybe you could have some simple tuning through RS232, then pretty much any of us could connect it up and do a little tuning, at least i'd throw on space for a max232 on your pcb, maybe we can put on some data logging as well!
I dont think this guy wants to get that elaborate. with data logging and all, Its a nice thought, but I think his main aim is to get a CHEAP, OPERATIONAL, SLIGHTLY TUNABLE EFI. Not full stand alone race ready tunable.
Yeah, that's true, I'm sure getting it working will be the biggest hurdle, the bells and whistles can be worked on after the fact just as easily.
Yeah, I can go load it up with 15 sensors, 5000 lines of code and have a super tuner efi kit...but they have those already for $700+ The chip family I am using is the Atmel AVR which is being written in C so 'IF' I wanted to move up to a bigger chip it would only take about 30 seconds to have the complier make it for the new chip. But, yeah let me get a prototype working and see if it is suitable or needs more electronics. :thumb:
Update 11/02/08: Design progress overall 40-50%
Tasks complete
Fuel injector drivers tested.
Trigger circuit tested.
Main program done. (no FI map yet)
Tasks upcoming
Test fuel injectors
Design/prototype fuel pump driver
Layout fuel system and order final parts
Start FI map
Below is an image when I was testing the trigger for the injectors. Final board size should be smaller than the one in the picture.

Very cool!
if your skiming on the sensors wont it run like crap with the changes in alt?
only reason i'd want a EFI GS is if i started taking it on raod trips...
last time i took my firebird to OR (im in CA) it was almost unable to make it over the border..
.
you go from sea level (at my house) up to several 1000' (3k+)
and i cant imagine a small 500CC twin doing anybetter then my V8 350
i would like that! :cheers:

No, I am not selling nothing ... I am just buying carburetors that are now worthless.
You dont want to sell your carbs ... well ... they are worthless ... but I will use them as pillows, paperweights, dinner plates, votive holders, remote controls, and as hood ornaments.
No hateful nothing ... once there is FI, who'll want carbs.
Cool.

Bringin it back from the dead, Did he ever finish this project?
This thread has popped up here a bunch. I swear to god when I become a senior I will make it my senior design project to EFI the bike. Everyone seems to start it. No one can finish it. :D O0
There is another clown who has come up with this same brilliyunnnnt Idea. I am going over there with several buckets of cold water, and as I throw it on him, he is using it to perfect his intake moisture content and temperature sensors.
Apparently the GS being inductive pick up ignition is really cool for doing EFI.
Cool.
Buddha.
apparently not cool enough to prompt anyone to follow thru to project end!
I don't know, EFI would be cool, but at least the GS carbs have a known working configuration. It might take people a while to get there from time to time, but it seems like building an EFI system for the GS would be like trying to tune a carb totally blind. It seems like it would take a whole lot of work. There is probably a pretty good reason Suzuki hasn't already done it, and I'm sure they have people who sit around all day doing nothing but designing fuel injection systems...
what if someone got themselfs a pair of TU250 FI setups and put them on the gs would that work?

You might be able to adapt parts from a bike like that to work with the GS, but you still have a whole lot of work to do in terms of timing and things like that...
oh i dont want to do a fi on my gs i love the carb setup on this bike. was just throughing that out there if someone wanted to try it.
I would think the Euro spec 250 Ninja fuel injection might more easily be modified. Smaller cylinders, but it is a parallel twin.

Wouldn't it be easier to just double up with single cylinder 250cc fuel injected bike parts? If you have a fuel injection system designed for one cylinder of approximately the same size as a GS cylinder, you'd be most of the way there....
Thing I like about carbs is if they play up I can fix them on the side of the road with a pocketknife and a rock. Try that with EFI.

Yeah, but the thing about EFI is: once you get it working right, it won't fail and leave you at the side of the road. Since EFI has so many fewer moving parts and most of those parts are extremely simple, there isn't nearly as much to go wrong. EFI basically replaces the highly mechanically complex carbs with a simple mechanical system and a computer that controls it. Solid state devices like EFI computers are extremely reliable and pretty unlikely to fail.

:flipoff: Carburetors - antiquated technology
Hello!
I am working on an efi for GS. The job it is 50% done. In short time i will go to test the electronics with the carbs on. I will use a throttle body and intank high pressure pump from kawasaki 600 ER EN. You can find some pictures at http://suzukigs500efi.blogspot.com/ (http://suzukigs500efi.blogspot.com/) (use google translate because it is in romanian).
Can you tell me what it is the code of that air filter ?
Update: http://suzukigs500efi.blogspot.com/ (http://suzukigs500efi.blogspot.com/)
I would at least use a Hitec 7955 TG. you do not want the servo to fail.
I am impressed!
I do not know anything about EFI but I admire you for not deserting your project as soon as the first problem appeared.
I have no idea how much more work is necessary to finish this project but I wish you all the best.
Keep us updated
Hurry up and mass produce your EFI kit for cheap lol. I cannot stand carbs.

:flipoff: Carburetors - antiquated technology
If carbs are so out of date then why do major companies keep coming back to them? For example the Ford SVT team just built a prototype F-150, Mustang, and Focus, all with 5.0's using carbs, to get better mpg than current efi setups while producing ridiculous power levels. EFI is a giant pain in the chicken, which when it fails, is impossible to fix without the proper tools. Yeah this is a neat idea, but the carbs on these bikes are simple, reliable, and super easy to trail fix. And a rebuild on one costs like $15 for OEM parts. I've fixed these on the trail I don't know how many times now after sinking them under water, bouncing the bike off trees and rocks, piling it up after a jump, etc. Hell, once I hit so hard the carb ripped off and landed like 10' from the bike! Do that with EFI!
Buhda, why are the newer carbs worth less IYO? As in what changes did they make that you don't like, and am I gonna have to drill out my old jets for your new jet kit?

Thanks for your post. I think the fuel economy it is a + for EFI. For me , the reason for this conversion, it is a good method to learn something. The EFI system involve computer programming, micro-controller programming, mechanics and electronics. In one word it is about MECATRONICS.
I am graduated Mechatronics/Mecanics faculty from Bucharest(Romania) in 2002 (and now i am game programmer).

I'm very curious to read more about this. Do you have a link?
Welcome back by the way. Hope you heal up quick.
if it's that cheap and pretty much plug and play count me in!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :icon_mrgreen:
Hi everyone. We have begun the build (rebuild) of the GS500 EFI based on the Blog and documentation (http://suzukigs500efi.blogspot.com/), created by Cristian Vasile. With his permission we are rebuilding the prototype he made and redesigning the whole thing from scratch to make it compact (with SMD components), waterproof and generally give it the spick and shine it needs. Most importantly we are doing all that with the final price in mind and are putting together a complete kit for anyone to convert his/hers bike with Throttle bodies, sensors and all the other stuff needed to make the entire conversion.
If anyone is interested then feel free to read about the project here (http://www.gizmoforyou.net/site/projects.html?section=projects&workspace=61&task=display_details&id=61&4e8c3cb101fe2dde1a5afa5efb4dd2fb=1).
Some people like to tool with carbs, others like to start their cold bike in public without sparking the ire of those around them. To each his own.
Keep us updated.
Tnx for the reply. We have allot of projects going on on our website. If you are interested in the progress and final product then Join the Group for the project. All updates and announcements about the project are made there.
is this easier and cheaper than using megasquirt and some other bikes throttle bodies?
Don't want to speculate here but we estimate the whole kit (including cables, throttle body, pump e.t.c) to be cheaper than the MegaSquirt EFI box alone :)

As someone who used to install and mess around with www.034efi.com and megasquirt, I'll be sticking with my carbs thank you very much.
If you want EFI, get a bike that has one already.
I'm not hating on the developers here. I'm sure they are capable, its just that your average person doesn't know how to tune EFI well. If your doing something plug and play, thats cool, but anything open source that requires an O2 bung installed in the muffler for datalogging or a dyno, then I'd say just save your money for a different bike.
That being said, good luck coming to market.

I will follow the blog closely,
do you have Twitter account that I could follow? If not I think it would be a great idea to get one.
We could get notified as soon as news are posted!
good luck with the project!
EFI isn't for everyone. As a rider my self i also was hesitant about the idea as i like to tinker with the carbs allot and fix them my self is something goes wrong. Having the thought of the ECU failing crossed my mind allot of times especially if it is made by another manufacturer even if i can fix it my self. Things change allot when the whole device is Open Source and you have a community behind you. Replacing parts is as cheap as changing a seal (if you are up to it)
Having said that, i think there is a bit of exaggeration when talking about a Dyno since most regular riders would never need it unless you intend to race allot in which case you most probably already know what to do. As for sensors we are sure to have a good explanation of what goes where and how to assemble the thing together.
In any case it is a preference. If you can change the oil filter on your bike (knowing where it is) then you will probably be able to install the kit. We shall definitely have a default setup, which will be tested on a bike and ridden well before any sales.
In any case, we posted the links in our reply for the project. If anyone is interested then join the Group of the project on our website. We have allot of other projects which we monitor and although we shall be visiting replies here, our main work space is on our website. Feel free to post any comments or suggestions there.

I COME IN PEACE.
With that being said, I think you are making it sound overly simplistic. Power to injectors? Power to coils? Power to ECU? Power to fuel pump? TPS? O2 sensor?
Ok, can the charging system take that? Are you providing the harness or is the customer making it? If your system comes stock, how can you adjust for altitude changes?
Is it really 250 bucks with the time it takes to modify a harness from scratch?
I used to build firewall harness plugs with 034 EFI and that used to take me 40 hours to complete a harness from scratch, running lines, testing voltage, etc. That system is extremely well thought out but if you are a novice, it takes a long time to learn this stuff.
Like I said, I really do wish you guys the best of luck. But I've seen many projects like this on other forums and usually when someone says this "EFI is plug and play, easy to install, etc" its usually not.
EDIT: oh yea, forgot to mention, if you EFI anything and don't run an 02 datalogger or take it to a dyno, you are asking for major trouble. That is not a good idea at all to do.
We never said it will be Plug and Play, Easy to install or cost $250. What we did say was the kit will have everything you need to get it working and will be affordable.
For the time being we are working on the schematics of the device and haven't added anything additional except for what was part of the original design. Once this is finished we shall look into adding and modifying the design as needed.
If you have any suggestions about the project then we are more than happy to listen in our project section or the Community group of the project. As for the Power, system and other issues.. You should actually visit our site and see what we do. :) We aren't doing this since yesterday and this is by far the most complicated thing we have done so far so no worries about it working properly.

Assembled its 450. Parts alone is around 180 or something. You mentioned before its going to be cheaper than the megasquirt box but more than 100 dollars because "the throttle body costs 50".
I don't have any suggestions for your project other than my criticism for it. Its just a fair warning to people reading this thread.
Also, don't be condensing by telling me to go your site like that. I already did and the first post is the guy saying he is quitting. There are no visible links to your "project section" and it looks to me like a Wordpress blog that you just took over from him.
I love hearing "No worries about it working properly"
I may be new to the board, but I'm not afraid to share my opinion. I'll eat humble pie if you guys actually build something, but to me it just seems like an overly ambitious project for an application that really doesn't require it.
And remember before you post back to me, this is a public forum. I'm not trying to be mean, I just have a completely different opinion than you. Good luck and I'll refrain from posting anymore, I don't want to seem like I'm picking on you or something. Just my .2 cents
Nicky,
I am sure that if you read through the project description, you will find all the links to everything related. We just started the project yesterday so don't expect to see the finished project any time soon.
Not sure what the whole fuss is about here, we done many projects and we are doing this one as every other for free and sharing all the designs. If someone doesn't like what we do or the project in general then simply ignore the post. Putting negative feedback on an Open Source effort is really unnecessary at this point when the project just begun.
We aren't resellers and we aren't a cheap retail store. Our work and the feedback from the community can be clearly seen and found. The Original EFI can be found on YouTube (http://www.youtube.com/watch?v=OReMph27Cqo)working so there is no reason to doubt the original design. We simply want to make it smaller and cheap.

We shall do our best to describe how to install the system and select the best Throttle body, pump and other parts so it is as simple as possible to install. The rest we leave to anyone who wishes to do it. Hopefully this will turn out as good as we expect it to.
Here is an idea that I think could help keep the project cost down. Instead of replacing the carb hardware completely, you could just strip the unnecessary parts and reuse the original GS500F carb since it already has a TPS sensor and vacuum ports and such built in. The injectors could be incorporated into the existing carb (which requires drilling and sealing up the hole around the injector) or added post carb straight into the rubber necks that connect the carb bodies to the intake ports. Best solution... no... MacGyver solution.. i think ..yes. :cheers:

itd probably much easier to machine a new throttle body than try to turn a carb into one
Tnx for the idea guys but it really would be much cheaper to just get a compatible throttle body as the one from Polaris Indy 500 and incorporate all the necessary features into it. Don't forget that we are trying to make this as simple as possible so that others can install it as well.

Im curious... why would it be easier or cost friendly to machine a new one?
I just looked at a Ninja 650R throttle body assembly next to a GS500F carb (both parallel twins and closely sized), and the throttle body is just a stripped down carb with an injector port. That is why I felt it would be more cost effective to reuse what you. In the simplest form, a throttle body is just a stripped down carb with the fuel metering circuitry removed from it.
