My EFI 'kit'

[O.C.D.]

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.

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If carbs are so out of date then why do major companies keep coming back to them?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.  Every problem solved motivated me to solve a bigger problem. For me this project it is a proof that only time is the big problem.

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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi everyone. We have begun the build (rebuild) of the GS500 EFI based on the Blog and documentation, 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.

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.

[skirecs]

is this easier and cheaper than using megasquirt and some other bikes throttle bodies?

[Gizmoman]

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

Very interesting

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 like the sound of that! Very interested!

[kml.krk]

very interesting.
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.

We are on Twitter, Facebook and other sites as you will see from our website but our main updates go into the project Group which we suggest anyone joins if you want to keep in touch with any progress.

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.
