My EFI 'kit'

[JeffD]

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     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.

Sounds sweet. Keep us posted with MORE PICS! Oo and updates..

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!

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.

$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.

[Darkmyst]

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.
