Installation of TunerStudio and MegaLogViewer (for Windows, Mac and Linux)

-TunerStudio is the software created by EFI Analytics used to configure all versions of the

MS3Pro. The software with basic functionalities is free. For advanced features like custom dash

www.PerfectTuning.net 4 July 2015

boards, auto tuning and diagnostics you need to purchase the software. It’s possible to

download directly TunerStudio at: www.tunerstudio.com/index.php/downloads. When a

computer is connected to a MS3Pro for the first time with an USB cable, a driver may be

needed: http://www.ftdichip.com/Drivers/VCP.htm

Here is a custom dashboard created by users on MsExtra forum. You can see more dashboards

in this thread at: http://msextra.com/forums/viewtopic.php?f=122&t=36862&start=80 like

these from different users:

-MegaLogViewer is the software used to view the data logs created by TunerStudio, internal

MS3Pro memory or even the data logs created by the Android phone or tablet software. The

software is also free but you need to purchase if you want to have access to nice features like

Scatter plots. www.tunerstudio.com/index.php/downloads

Software for Android devices

-Shadow Dash MS is the Android TunerStudio version. You can download it here :

https://play.google.com/store/apps/details?id=com.efiAnalytics.shadowdash for 9.99$

-MsDroid display real-time data and it’s also possible to edit the tune. The software is completely

free! https://play.google.com/store/apps/details?id=com.msdroid.

If MsDroid shows a connection error message go to

http://www.msextra.com/doc/ms3/files/release/ and downloads your MS3Pro software version

(by default 1.5.0) and extract the ms3pro.ini file to the MsDroid/ini folder on your Android

device.

-RealDash is a application available for Android, iPhone and Windows that can display really nice

dashes.

Software for Apple devices (iPhone, iPad)

-RealDash is a new application that will be available for iPhones with really nice dashes. Still no

official releases in April 2016. This requires the internal WIFI module.

Installation of the MS3Pro-PNP.

1. Connect the MS3Pro-PNP

Disconnect the battery

The factory ECU is located on the passenger side kick panel. Remove the plastic cover over.

Install the MAP Sensor vacuum hose/tube to the MS3Pro-PNP unit. Connect the vacuum tube to

the manifold vacuum port where the fuel pressure regulator is connected.

The MAF sensors are not required and not used anymore.

2. Power up the MS3Pro-PNP

Put the key on when the ECU is connected and listen if you can hear the fuel pump running for around 3

seconds then turn off. This indicates that the MS3Pro-PNP is functional. It’s possible to look at the two

led on the MS3Pro-PNP. Red is for power to the MS3Pro-PNP and greed is active when fuel pump is ON.

3. Connection to a MS3Pro-PNP with TunerStudio and a USB or serial cable.

You might have to install the software drivers for the MS3Pro-PNP if it does not install automatically.

You can download it on the FTDI website at: http://www.ftdichip.com/Drivers/VCP.htm. If you are using

a USB to serial adapter, please refer to the manufacturer website for the drivers.

1. Plug the USB cable to the MS3Pro-PNP and your computer

2. Open TunerStudio.

3. Press on File, Project, New Project

4. Give a project name.

5. Put the key in the ON position to power up the MS3Pro-PNP and click on Detect. TunerStudio

will automatically detect the MS3Pro. If this step fails, put key in the off position and try again.

6. Press Next

7. The next window will let you choose between units you will want to use (Fahrenheit or Celsius).

Leave the other options to default and press Next.

8. The next window is to connect TunerStudio to the MS3Pro-PNP. Be sure to select the right port.

The baud rate will always be at 115 200.

9. Choose the desired dashboard. Click Apply.

10. You are now connected to your MS3Pro-PNP.

For more information please visit: http://msextra.com/doc/ms3/serial_setup.html and

http://msextra.com/doc/ms3/tunerstudio_setup.html.

4. Calibrate the «TPS» (throttle position sensor)

Turn the key to the ON position, then connect TunerStudio to the MS3Pro-PNP. Go to Tools, Calibrate

TPS then click on Get Current for the closed throttle ADC count while NOT touching the gas pedal. Now

with the gas pedal fully pressed, click on Get Current for the Full throttle ADC count.

www.PerfectTuning.net 7 July 2015

5. Calibrate the IAT (intake air temperature) and CLT (coolant temperature) if not

using the factory one.

Please note that when this dialog box open, the previous value is never loaded because this information

is saved in a data table and there is no way to know which sensor you chose previously.

To calibrate the sensors, you have to connect TunerStudio to the MS3Pro then go to Tools, Calibrate

Thermistor Tables. Select Air Temperature Sensor for Sensor Table and 3 Point Therm Generator then

in Common Sensor Values, select your sensor. Press on Write to Controller. Do that again for the other

sensor.

6. Calibrate the Wideband

Please note that when this dialog box open, the previous value is never loaded because this information

is saved in a data table and there is no way to know which sensor you chose previously.

If a wideband is used and it’s suggested, connect it to open TunerStudio. In TunerStudio, select Tools,

Calibrate AFR. Select your wideband sensor in the list or select Custom Linear WB and enter the values

manually with the manufacturer specifications.

7. *** IMPORTANT *** Check the timing and Check It Again!

This step is very because the timing signal is generated from the CPS (cam position sensor) signals and

the CPS can move. This step is here to ensure that the timing of the MS3Pro-PNP is synchronized with

the engine. If you do not perform this step, YOU CAN DAMAGE OR DESTROY YOUR ENGINE.

Remove cylinder 1 coil on plug, install a spark plug wire between the coil and the spark plug and connect

the timing light there.

Connect MS3Pro-PNP to TunerStudio then go to Ignition Settings and in the field Fixed Advanced, select

Fixed timing. Enter the value 10 at the Timing for Fixed Advance field.

Start the engine with fixed timing at 10 degrees. Check with a timing light if the timing is right. If not,

you need to adjust Trigger Angle/Offset(deg). Then, rev the engine and ensure that the timing stay at 10

degrees. If the timing drift, you can play with the setting Spark Hardware Latency.

What to do if the engine don’t start

To prevent flooding the engine with fuel, it’s possible to press on the gas pedal at the maximum when

you turn the key on and during cranking. This activates the flood clear mode and completely stops gas

injection. You can also edit the Required fuel to 0in Basic/Load Settings,Engine and Sequential

settings. This will completely disable gas injection at all time.

www.PerfectTuning.net 8 July 2015

Ensure that the Crank and Cam synchronization is good. The Synced indication in TunerStudio will turn

green while cranking.

1. Ensure that the spark plugs are firing and you can check the timing while cranking.

2. If the engine seems like it want to start, you can try to slightly press on the accelerator pedal to

see if it helps. If the engine starts this mean that fine tuning is required for startups.

Connectors

Expansion connector

This connector contains the access to all the inputs and outputs to add more functionality to the

MS3Pro-PNP. This is the view of the connector on the ECU. Note that the numbers are also noted on the

connector plug. See Inputs and Outputs section for more information about the functionality of each

pin.

Wideband connector and controller

The internal wideband Bosh LSU 4.9 controller is optional. To know if the controller is present inside

your MS3Pro-PNP, look at the serial number sticker on the back of the MS3Pro-PNP. When the

controller is present, the provided wideband sensor will connect directly to this connector and will

output a 0-5v signal on the expansion connector pin #12; 0v = 10 gasoline AFR and 5v = 20 gasoline AFR.

If the internal wideband controller is not installed, it’s possible to use any external wideband controller

that output a 0-5v signal on the expansion connector pin #12.

Inside the MS3Pro-PNP, there is a small jumper named “Wideband”that allows selecting if the MS3Pro-

PNP needs to read the signal from the expansion connector pin 12 (right position) (internal or external

wideband) or the signal on the factory oxygen sensor (O2).

How to crimp a wire for the expansion or wideband connector without

the right crimper.

1. Strip the wire like the picture:

2. Insert the wire into the connector:

3. With long noses pliers fold the small edges.

4. Then fold the long edges:

5. After the connector should look like this:
