# of cylinder setting

[smithabusa]

Tony,

Dumb question, but when setting up your Reqfuel you have to enter number of injectors and number of cylinders.  On my stuff # of cylinders gets set to 2 when using the tach signal.  If I make # of cylinders 2 and # of injectors 4 the req fuel value changes (the lower one in the greyed out area).  Is that cool to do or no?

Yes just set it to #cyl.2 and inj4 and let the req. fuel change thats fine also set the injection 1 squirt  and Simultaneous.

 What size inj. are you running

RC 650cc.

Man i can see this is addicting, if you get ignition all sorted out i could be interested in stand alone.

Yeah i hear you i have been working on all the ways to get extra outputs and features for three months now.LOL

Ok go to the required fuel and use the calculator to change the req. fuel for your inj it should be around 8.0 and 4.0 with a afr of 12.5.

Yeah as soon i get the interface board done if you want to try one you will be first on the list. and you can use the MS you got now.

You are exactly right 8.0 and 4.0.  I had 14.7 for A/F before as I wasn't sure if it had to look up gasoline table or something using that, kinda clueless on the req fuel calculation.

and def. interested in the stand alone, question though, how in the world do you know what stock ignition tables are?

Yeah the req. fuel is part or the VE equation along with other variables to calculate the inj. PW much easier to just change the req fuel when changing inj. then to have to redo your whole fuel table i have went from 24lb to 42lb inj and all i  changed was the req. fuel and it still was real close to where it needed to be.

I dont know what the stock ign tables are so i will have to do alot of road testing to get a good map made then i can send it to whoever needs it and they can tune it to there motor .

I have a ruff table started to get the motor running  and i will just fine tune it till it runs like i think it needs to. When you set up the ign. part you can start the motor with a locked timing deg say 10deg btdc to get it running then once you timing marks lines up with 10deg btdc on the crank or zero with a dial back light you are set to start tuning on the table.

The tables wont be that big of a deal the triggers are what im worried about see the wires in the stock harness are not shielded and i dont know if it will cause any cross talk in the vr signals or not but i will find out soon.

The crank triggers are always the issues with other stand alones from what i have heard.

The main problem with the other systems are they lock everything out so all you can set is the basic settings thats why they want you to use a 60-1 or whatever wheel they use the MS you can set it up to use the wheel you have but it takes a little testing to get it right i can set the exact tooth on the wheel that needs to represent cyl1 on most other systems you cant unless they write a specific program to use the wheel your trying to use and most dont want to do that.

Gotcha, i had heard on the microtec stand alone the had were having issues with crank triggers i thought, and it was specifically for the busa i thought.

Yeah when i talked to Richard he said the same thing it would start up and run one day then the next day it wouldnt.  I  dont know exactly whats going on with that other than maybe its not seeing the cam trigger or something.

Interferance from the alternator.... improves if you seperate the crank pickup wires from the alternator wires. but the crank pickup is a very "dirty" signal, seen Autronic loose signal on the cam too , can't rev passed 8.5K , even a motec i fitted was throwing an occasional sync error.
This will be one of your biggest probs with a standalone.

Gsxturbo i'll send you another brand ign map, should get you started in this area.

Thanks for the heads up i will be sure to keep that in mind when i start always good to have some input from people who have done it when trying new stuff.
