Shift Light on MS1

[smithabusa]

Tony,

On the phone you were saying I could use pin 10 and 11 on the CPU for shift light, I see what you mean about how it doesn't work the way you would expect.

Question for you, if I want to use that as the actual launch light and I thought I read in the manual somewhere you can use X4 as a RPM output. 

If I select Output 4 as RPM, then try and type in a value (no clue what i am doing here by the way) it tells me i can't go higher than 255 and it looks like a temp setpoint.

What I am doing wrong?

Ok you cant go  any higher than 255 because that is in raw adc value 255 would be 25500 rpm say you want it to come on at 7000 type in 70 and see what it does

You can also go into the nos section and use that as an output for the launch light  since your not running nos you can also use that to add fuel while setting on the two step just add the % fuel you want to add while its on and you can set it like normal also use pin11 for the upper limit so go into the shiftlight section set the upper limit dont worry about the lower then set tach out to pin 10.

In order for it to add fuel while on the two step you will need to make the pin6 on the JP1 header go low you could do this with a signal from the clutch switch so as soon as you let the clutch go it would go back to the normal fuel setting.

You have a recommended source for buying transistors and baord etc?  The local electronics store has baord i think but if i remember correctly rediciuously expensive.  I dont have any transistors or anything to try it out so will have to order some up/.

Perf board you can get just about anywhere like radio shack or something like that get a big piece and cut it down to around 2x4 it will slide inside the case then and you can add the circuits you want.

Or digikey will have them also
 
For the transistors look on ebay there are tons of surplus stock on 2n2222 transistors you might get some PNP's too i think they are 3905 but im not sure just lookup transistors and you will see i usually buy them 200 at a time for like 10.00.

Also get some 1k  1/4 watt resistors  and some 1n400x diodes you will need them also.

Dumb question as I am new to transistors etc.  What is the significance of the 1000 ohm resistor?  You have a 0 or 5 volt signal coming from pins 10 and 11 right?  Is that what is requires (1000 ohm) to bring the signal down enough for the transistor? 

What I am wondering if I want to complete this circuit using the clutch signal ground using a transistor (instead of a mechanical relay like i normally use) what resistor should i need?

[smithabusa]

I shot you an email also, somehow i locked up X4, its all grayed out, i tried and it lights up on the bottom of the screen when i go over 10,600 RPM like i told it, I il lhave to figure out which pin that works and get a transistor working off it.

[Gsxturbo]

Ok hold on i will see whats going on send me your msq in an email and i will fix it for you.

[Gsxturbo]

Is it X4 or output 4?

If its X4 go into coadebase ouputs and function and change it from boost control to output 1

If its output 4 change LED 18 to output 4 in the same place.

Its Output 1 (X4 / JS2)

[smithabusa]

Cool went to the codebase and output function and changed it from b control to output 1, seems to have fixed it, you the man

I think i realized what to do on the launch light, just use the clutch signal ground as the Emitter going into the transistor i think.

[Gsxturbo]

Yep that will work that way when the clutch is in the emitter will receive the ground signal and flow through the collector.

[smithabusa]

do transistors care whats on the collector side?  meaning can you run the output of the shift light and launch light to the same location (using just 1 LED cluster). Putting a ground on the collector when nothing is at the base, that cause problems?  Man this is fun stuff

[smithabusa]

Im excited now to get a tach output working (assuming i need more transistors LOL) and be able to test my 2 steps and shift lights etc without ever having to start a bike.  right now i have no pulse generator for a fake tach signal

[smithabusa]

X4 i have now setup as 7000 RPM, I get a voltage of 12 volts below 7000 rpm if i take a probe to the +12 volt input on the stim and the other probe on X4, when it goes over 7000 RPM it goes to 7 volts, its changing, just dont understand what its doing LOL

[smithabusa]

Cool on the screen anyway i have setup as the launch light to play with 5000-5500 RPM and have Output 1 (X4) set to 10,600 RPM for the shift light.  Works in theory anyway LOL

[Gsxturbo]

Ok where working with logic level stuff so when the set point is not met it should be low or 0v now when the set point is met the pin will go high or 5v logic level that will turn the transistor on just like a switch.


Now if the signal is high then goes low its the opposite the transistor will stay on till the set point is met then it will go off

This is with NPN type transistors with PNP its the opposite but instead of flowing ground to the collector it will  flow a + 5v or 12V witch ever you have hooked the the emitter.

Thats how i thought it was supposed to work (0 or 5 volt) should i be putting the probe somewhere else besides the battery connection on the stim?  The only way i can see something change is to put red lead on the + terminal on the stim, and the negative lead on X3 or X4, it goes from 12 volts when conditions aren't met to 7 volts when conditions are met.

[Gsxturbo]

Yeah your getting a 5v ground signal thats why it reads 12v when its off and 7 when its on.

You can still use pin 11 for your upper limit shift light  but pin 10 wont work no more when your using it as a tach out then you will gain the general purpose output back.

its not supposed to work that way though is it?  The diagram in the manual states to use a NPN transistor
