Shift Light on MS1

[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

Whats not supposed to work that way? You can use a PNP or NPN depending on what your trying to do you can even use a PNP to trigger a NPN or vice versa depending on what your trying to do.

I just mean that I am getting a 5 volt ground out of X3 and X4?  I haven't added anything to the board, just probing it with a voltmeter with the stim plugged in to see how it works.  From the manual i thought X3 and X4 were supposed to give 5 volts when activated on a stock board before adding transistors etc.

[Gsxturbo]

Yeah it should stay grounded till the set point is met then it will go high or 5v your getting full ground when its not met so you see 12v now when it goes does go high your meter is reading 7v because its feeding 5v through your ground lead and subtracting that from your 12v reading you where getting.

Im may be confusing you i do that to my self quite a bit.LOL

[smithabusa]

if it feeds 5 volt through my ground lead shouldnt i be able to see that by putting 1 lead on x4 and the other on the ground terminal of the stim where the battery would plug in?

[Gsxturbo]

Yes put your ground lead on the stim - terminal and the positive on the output x4-x5 ect and you should see 4.9 or so volts when it turns on.

[smithabusa]

I dont for some reason, but I just rememered why and it works LOL.  You gotta be regretting ever talking to me by now LOL.

Very strange thing between my wall plug and the blue block terminal.

Its plugged into the wall, everything works, but....

I now remember this when i first put it together.

I have continuity between the ground on the blue block and the ground in the wall plug receptacle.

I have continuity between the wall plug receptacle power (center pin) and blue block +.

I have continuity of power from blue block to receptacle center pin.

But I dont have continuity of ground.  I cant get a ground signal off of the - terminal on the blue block, even though it has continuity to the receptacle, if that makes any damn sense LOL.  I remember scratching my head on this when i put the stim together.

I cant read 12 volts across the blue block where the battery goes.  I can read the + side using the walls plugs outer casing as the ground, but not vice versa. 

Now using a real ground, I from the wall plug outer casing, and probing the + lead of my multimeter on X4, its 0 and 5 volts, HOLY MOLY!

Maybe there is a protective circuit built into the stim that keeps you from seeing anything from the battery terminal. My original stim was an older vr. then i got the jimstim so im not real sure on the stim you have with both the battery and wall wart plug on it but atleast you see how it works this is how almost any chip works logic level wise low is ground and high is 5v PWM is a different story.

No i dont regret talking to you most people dont want to even try this kind of stuff i enjoy messing around and seeing what i can tear up. LOL

Thanks very much for all your help Tony!  I did get the logger software installed, I logged an excel file, then opened it up and looked at the data, so i got that working unless there were other steps to take etc.

I sent you some beer (sorta) for all my damn questions, i know how it is when you are trying to get work done but can't get away from the keyboard LOL.

he is great to deal with and is always willing to help
even someone like me lol who breaks everything lol

We are up to like 30 posts over a shift light LOL.

I can send you a log file from a busa on the road and you can see what it looks like and the tunning console is used to auto tune your ve table if you have a wide band you load your MSQ  you were using at the time of the datalog you open it in the tunning console and it will show your VE table in the screen then you can let the datalogger tune your table for you.

Also you will need to activate boost in psi and the type wide band your using let me send it to you the MSQ i sent you was from the datalog and you will need to activate LC-1 as the widband and show boost in PSI .

Give me a minute.

Cool Tony,

How do i get the VE table to recalculate once I have changed my req fuel value?  I redid the req fuel and still see a row of 16's i typed on the bottom to get the injector LED's to fire on the table with no boost signal.

Thats the thing you dont need to reset anything in the VE you just reset it when you changed the req. fuel see the req fuel will scale the opening time back for the whole table so that table was for 42lb inj. with a higher req fuel now you just rescaled it by changing the req fuel lower .

Now this is not to say you wont need to do some tuning here and there but not the whole table thats what so nice you change one thing instead of starting all over again.  You can also scale the ve in the table but thats for a later discussion. 

[smithabusa]

Im a little confused LOL.  But maybe I understand, so the line row of 1's that were in there that I made into 16's i should go back and fix right?  Also if I remember correctly it seemed the boost didn't go all the way up to 250 kpa in that table, what happens when I change the values to go all the way up to 250 kpa, will it change things as I retype them in?

[Gsxturbo]

Yes the bottom row will need to be 1's to keep the inj off till in boost once the kpa point is reached 105 or what every you have the lowest kpa bin set to it will start firing the inj. if your just testing on the bench you can leave them like that . but before you put it on a bike it would need all the lowwer bins set to 1 and always 1 even if the datalogger changes them to 2 or 5 or whatever you will need to always keep them at 1.

Yes it will change them as you type but you will have to hit burn to burn them into flash or otherwise it will lose what you typed in when the power is cut.

I can send a table i made up for 22lbs of boost if that will help you out on the kpa bin part it might give you something to start from now this is a high as you can go with the 2.5 map sensor you have.

What i was saying about the required fuel part is, instead of changing the whole table because you have bigger inj. then what the map was made with ,all you do is change your req fuel instead .

Always leave it at what the MT calculates for your req. fuel unless your fine tuning your table and even then it not really necessary to change it.
