on the 2004 12s what is the cheap and easy way to get rid of the air box with the motor control for the interactive muffler valve. What are my options? I'm new to this cycle and it has been wrecked so I'm trying to customize it to be simple as possible, still keeping the fuel injection. thanks | ||

Do a search on servo eliminator with my name (xbolt12)in the archives. I designed a simple circuit that fools the ECM. You are free to use the design, but not to sell it. xbolt12 | ||

"You are free to use the design, but not to sell it." Dude, once you placed it on here it became public property. He's free to do with it as he wishes. Go ask any patent attorney. | ||

Gowind... i think he meant .."Gentleman's agreement" AKA.. "i don't charge people for using my design so please don't charge other people" | ||

Open Source sort of thing, also known as a Copyleft. (go ahead, google it, I dare ya) | ||
| Gowindward |
The whole point is that once you place your "idea/design" in a public forum like this one, is that you no longer "own" it or have control of it's use. | ||

I did a search and found Opto's, but not yours John. It is the same? A 10k and 1.2k ohm resistor I can find, but I don't know enough about electronics to know what a BC337 is. Is that something I will be able to find (will they know what I am talking about?) down at the local electronics store? Thx, Andrew | ||

It's a transistor. I'm making one up for myself and picked up a few extras. | ||

Well if Gowindward is going to be such an ahole about it, maybe I had better put a copywrite notice on the schematic first. Which is what you do to protect a circuit design anyway JERK. It just so happens that I spent a lot of hours getting things working, yet I thought I would share with fellow Buellers. Ya know, I thought it was mostly the Rice Rocket boards where people always have to criticise or point something negative out, but it seems to be on this board as well. So I say to you Gowindward, YOU don't have my permission to use my circuit!  And it just must be that somehow the copyright John Stahl got deleted from my original post. Buellboard, send me an email and I'll send you the schematic free of charge. xbolt12 | ||

xbolt12, Sorry for pi$$ing in your Cheerios! | ||
| Xbolt12 |
It's ok Dewd! | ||
| Xbolt12 |
Hmmm Rice Rocket kid phrases too. | ||

Well if you've got some extras Chris, I'd like to take what I need to make my own off your hands. I would rather source the parts from someone who knows what they are doing and how to do it. A simple diagram, like the one Opto posted would be mighty helpful too. Let me know what you need from me. | ||

Gowindward - his publication on this board constitutes disclosure - he can have 12 months to reduce it to practice should he decide. If he decided to patent it and you were found to be producing a prototype after his public disclosure, GUESS WHAT!!?? - yo'd best be talking to that above-mentioned patent attorney of yours because he has a date certain AFTER WHICH you used his disclosed data/invention/concept... Pretty clear. Besides all that - there's just no reason to be such a prick about it. There are just too many "amateur socialists" out there assuming that just because they see something - it's theirs. Yeah, I have an attitude - and yeah, I have more than a few patents. | ||

Mine is not a transistor, it is an optocoupler and opamp inverter. All parts except the factory wiring connector and the optocoupler are available at Radioshack. I used an older design optocoupler, but some of the ones at Frys would probably work just as well. If you send me an email I'll tell you where to get the factory connector for about $6.00. Opto's circuit will probably work as well, but I think I had a transistor (HFE equivilent) with a different Beta (gain) that what Opto used and it didn't switch well enough on the bike when running through the diagnostic procedure to convince me it would work reliably. However, Opto and others had success with it, so again it was probably just the particular transistor I had. xbolt12 xbolt12 | ||

i should think that the transistor beta would not be relevant in a switching mode. its either on or off. | ||

Thanks Xbolt12, I'll check that out in old archives. Automotive EFI techs mentioned that FORD Motor Co. has a item similar to that. It is a plug in item. I'll find that out to let you know. Another Question will this allow me to do a exhaust system of my choice? Is there any remapping to do? Thanks, Rod | ||

You're right Fullpower, the beta shouldn't matter that much. If you test the circuit by holding full throttle and turning on the ignition (this cycles the actuator) it switches that fast that it's very difficult to measure with a DMM, unless it also has a bar-graph display and you keep your eye on that, or a max/min memory. From memory Xbolt12 I think you have the input and output part of your circuit diagram back to front (the text description was correct), I PM'd you at the time but got no response. Also at the time I wondered why you were using a dual comparator rather than a smaller single one with only 8 pins, and a 4N25 optocoupler would do the job and can be found anywhere... Anyway it works and that's the main thing. | ||
| Xbolt12 |
Good point on the Beta. I really needed an oscilloscope to accurately measure voltage changes which I don't have access to, and yes I was using a DMM. On the bench the ECM had trouble pulling the Control signal even close to 0 volts during the diagnostic test. Maybe it was a Vsat/Vce problem on the transistor?. The reason I used the dual comparator was because it was available at my local Radioshack and it was the perfect chip for the circuit. It can use a single supply and it can switch the output to ground with very low impedance much like a digital switch. I also used as low resistance as possible on the reference voltage because I wanted to get as much noise immunity as possible. As for the opto-coupler, it was what I had. Sorry about not getting the PM (guess I should start reading them) BTW: I am not an EE by any means, and my component knowledge is stale, but I did research the components to try to ensure they would work without damaging the ECM. xbolt12 | ||
| Xbolt12 |
Actually I think it was a quad comparator, but I have moved on to other things. Thanks Opto for sharing your design, it got me started on ways to solve the problem. BTW you guys were right the servo motor only measures fully closed and fully open. | ||
| Xbolt12 |
Yikes! Opto you are correct. My schematic is wrong! Anyone who is building this circuit needs to hook up the opto coupler diode anode (pin 2 on the 4N33 to the ECM Control wire and the output of the LM339 Quad Comparator pin 2 to the ECM Hall Effect wire. Basically, the Control wire hooks up on the left side of the schematic and the Hall effect wire is on the right side (output) in the correct drawing. The pins are #2 in the case of each chip, but the Control wire goes to the 4N33 and the Hall Effect wire goes to the LM339. Both the text and the diagram are incorrect. My original handwritten drawing is correct, but I transposed on the bmp I posted and emailed. I will correct the drawing and send it to those people I originally emailed. I will also try to change it in the archives (and add my notice Sorry for the confusion. |
