Just got the Microsquirt by the mail today  Looking forward to start installing it! I will use it on my Gsxr750 Srad from 1996 with turbo, original mounted with carbs... I have got hold of a pair of throttlebodyes from a Gsxr 1000 K2, witch fit right in the stock intake rubbers! Have any of you got a start up map I could use? |

I dont have one for a microsquirt but i could probably make something for you to start from (now it WILL still need alot of work ) but it would get you going in the right direction let me know what firmware you going to use and i will see what i can do.

Hi! Don´t know what firmware I use, have not hooket it uo yet... If I understand it correct, is the Mircosquirt tha same as Megasquirt II and can use the same programs/firmware!? How can I see the firmware at the moment? I got the box from www.diyautotune.com |

The Microsquirt does use the same firmware as MS-II, but you will need to watch out for a few things on the maps (the Microsquirt ignition settings are subtly different, and it has no PWM injector capabilities). I'm pretty sure yours shipped with 2.881 firmware - Bowling & Grippo just released a bug fix, so you might want to download the latest right here: http://www.microsquirt.info/uscode.htmOur MegaTune package download is configured for this - 2.881 and 2.883c use the same configuration file. |

There you go Matt's the guy you need to talk to when it comes to the uS i havet had the chance to mess with it so im not that familiar with it .
Also if you do intend on using low impedance injectors since you cant use PWM for them you could go with a board from one of the guys on the MSextra forums he is working on a Peak and hold board for the micro .

I am a bit lost in all these codes, and how to do this and that  I hope that a friend of mine, who is use to the Megasquirt can see the differents, and know how to tune it! I have absolutly no clue what PWM is? One more thing I just stumblet over is that in the tuning program, the meter for engine rpm´s is only to 8000rpm! How can I change that? |

The code is the the software in the processor, it is what tell's the processor to do what it does some code's do the basic stuff and some code's will do alot more stuff on top of the basic stuff the uS comes with a basic code on it witch will probably be fine for you right now then later you can change to the extra code if you want to do more stuff.
PWM is Pulse width modulation it is used for low ohm injectors to keep from burning them up.
I can make you a new ini. file for your MT to read whatever RPM you want.

It all starts to look like something now! Almost all the wires is hooked up now:) Are anyone using the tow wires for the led´s "warmup and accelration"? Also the "spare adc" wire for "baro" external mapsensor? What is it for? I have used a stock mapsensor from a Yamaha 650 turbo witch is a 250kpa sensor, but requiers 12volts for suply! So I have just given it 12volts ignitionsuply, not the 5volts from the microsquirt... Sorry for the bad pics! It is from my phone...        |

Sorry about that Tobisen i hit the wrong button.
The extra LED wires could be used for extra outputs and the spare ADC wire is used for a second map sensor for Baro correction.
I dont know about using the stock map sensor with the uS if it is feed 12v because it will return 12v to the uS and might fry something (Matt would be a better person to answer that) Also all the busas i have seen work with a 5v feed and return so i dont see why the GSXR would be different but maybe so.

The mapsensor is not Suzuki, but from a older Yamaha!
The output from the sensor is like a normal 5v sensor, it varry from 0-5volts!
Now I get it! The baro is ofcouse baro correction! Are you using that?
About the led´s, I dont have to use them so? Don´t want to look at them on my dashbord...

May be better off getting a GM map sensor, pretty much industry standard in aftermarket management and there will be calibration files available.
What throttlebodies are they ?

Yes i use the baro correction on some installs but its not a necessity, the leds wires can be configured for general purpose outputs like to turn relays on and off,ect. I would use a GM map sensor or one from DIY unless you have the scale factors for the specific map sensor your trying to use. |

The volt output from the mapsensor looks like any other mapsensor!
I´ll try to use it, an see what happens...
The throttleboddies is from a K1 Gsxr1000!
Fits right into the rubberboots:)

Well another thing is the stock yamaha map sensor is probably a 1bar map sensor meaning you wont be able to boost with it at all because it wont read anything above atmosphere.

Nope!
It is from one of the Yamaha with turbo!
It is a 250kpa sensor with 0-5volts output, but it just needs a 12v supply...
I got almost finish today:) just need to finish the new plenum and mount the air temp sensor and connect my wideband lambdasensor!
Hope to finish this sunday, so I only have to do the tuning...

Oh ok well let us know how it goes. Your plenum looks real nice i like your velocity stacks also. :thunbsup:

I had ignition on for the first time today, an hooked on the laptop to start all the configuration!
A friend of mine knows alot to the mega squirt, but he says this micro looks diffrent!
I don´t know that, this is the first time I try to use Megatune!
Is there any special things I need to know to set up ignition?
