my project target:
Story/description of my Device
* I have a servo controlled valve/guillotine on my 2-stroke motorcycle Cylinder (5Kohm dc 12V. 3,3W servo) , servo might be little wrong name to say..here is a sample video from web about Servo's movement range:
* servos range (video above) is clockwise and anti clocwise but never 360 around or anything else than shown in video above. Servo has a 1 solid regular 0-position or homebase where it sits/rests during siesta. 5Kohm potentiometer at servo is for the rotation range limiter, +/- polarity switch function.
*a ECU or computer unit (if i call it with such name..) follows a engine's timing impulse/rpm signal from CDI and when timing pulse/rpm is 7250, the ECU makes the Servo to rotate......
Timing pulse voltage/duration is xxxx (edited 23.03-2011, because of wrong written info)
My project is to make my own ECU with various rpm options or even adjustable option, compered to the 1 only solid 7250rpm command. My motorcycle manufacturer has 5 different rpm model ECU's depending about engine tuning level, rpm value is 1 solid value in each model but factory made models are from 7250~9000rpm
This kind of "aftermarket" adjustable devices are already designed and manufactured by some italians, with PicMicro mainly.
can somebody recommend me a needed Arduino microprosessor i-o board model and needed exstras on hardware.
Also a advice or HIRED help reagrding my project would be wanted as i am a nooby on Microprosessor controller world but i have been studying Arduino for past 2 weeks to get somesorta idea about it.
For my helper i would be paying money, if wanted so, as im already used/mentally depressed to being alone without anykind of help what so ever in my hobbyes to make them happen from zero to finish only by my self (my country aint socially very open minded...towards helping strangers and i unfortunately know this too well as a native)
Contact me and introducde your self and make your demands regarding paycheck (paypal Gift titled)
i can reveal tell much more about this very basic valve system on my bike including photos,videos ++ and same for the italian made projects that work.
the italian models have various functions on them like:
Functions at Microkontroller such as:
-LCD display with:
-Servo control with engine ignition timing pulse/rpm surveillance
-pre-set 50rpm step +/- push button for above function to control Servo rotation start-up r.p.m value.
-servo self cleaning action: valve open and closed at 500rpm and 2000rpm or what ever wanted and programmed.
-digital rpm tacho on the LCD
-AirBox temperature sensor reading
as you may now think or even better realised that i have tryed now many many weeks to get any what so ever help or bought material from the italians BUT none of them has anything to do or sell (lack of will)
Device that im targeting here as titled and explained is something that i have been dreaming now for 15 years. Those italian designers and manufacturers only popped up into out open only like less than year ago.
to explain even more about my factory made system on my 2T bike is this:
Servo has 5 wires which from:
* 2 are for servos motor (+ and - feeds)
* 3 are for 5Kohm potentiometer (1 wire for Ohm resistance near 0 value and 1 wire for resistance near 5Kohm. 1 data wire)
*CDi that gives 1 wire to Computer that controls Servo movement. this 1 wire gives the timing impulse at engine BTDC & TDC. Impulse voltage value is mentioned earlyer above..
*all Servos 5 wires are connected into ECU and also the 1 wire from CDi.
ECU gets dc +12V from ignition switch wiringloom, so that is its power Source.
Those are all wiring connections on the WHOLE system.
that simple it is.
with this project i do not only represent my self, i am talking from a behalf of our whole global Club of owners in our brand of rare race/road production motorcycle models.
ps. please feel free to ask any guestions also in this topic if wanted/needed.
