Introduction

This guide is a brief explanation on how to get started with calibrating the LT4

ADV Lambdatronic unit. The following information should be considered supple‐

mental to the LT4 ADV Function Manual as it does not cover all aspects of cali‐

bration and use. We highly recommend reading the LT4 ADV Function Manual as

this contains much more detailed information about the LT4 ADV’s functions and

settings.

Please follow the included steps carefully and in‐sequence.

Software Installation and Startup

Software Installation

Insert the Lambdatronic LT4 ADV Software Tool USB drive into your computer

and start the installer “LT4 ADV_Setup.exe” located in the USB drive directory.

The Setup Wizard will guide you through the installation procedure for the Mod‐

asSport calibration software and the drivers for the MSA‐Box interface device. It

is recommended that you use the default settings throughout the installation. Af‐

ter the installation procedure, a shortcut to the LT4 ADV Toolbox will be created

on your desktop.

Project Folder Installation

A project folder for LT4 ADV setup and calibration has been included on the

Lambdatronic LT4 ADV Software Tool USB drive. This folder, named “LT4 ADV”,

can be found within the folder “ModasSport_examples” in the USB drive’s main

directory. The LT4 ADV folder should be copied to ModasSport’s working direc‐

tory (typically C:\Bosch\ModasSport).

Setup in ModasSport

Upon opening ModasSport, the first window to appear will be the Project Man‐

ager page. Highlight the item “Bosch Motorsport Projects” in the Project List and

then select the button “Add existing” in the “Project” group:

Navigate to the working directory for ModasSport as per step 2.2, open the “LT4

ADV” folder, and double‐click the file named “LT4 ADV.mxprj”.

The Project Manager page will now list the project “LT4 ADV” with a workbase

“LT4 ADV_1B ”.

Calibration and Live Data Viewing/

Recording

Connecting to your computer

Before beginning calibration or data viewing, insure that the LT4 ADV is connec‐

ted to your computer through the MSA‐Box and is powered.

Double‐clicking the new workbase “LT4 ADV_1B ” will open the project workfold‐

er and begin the connection process to the LT4 ADV. Once connected, the status

indicator at the top left of the ModasSport window will turn green.

When connected, this

light will be green

If the connection attempt to the LT4 ADV fails, an error window will be shown:

In this event, check the notification area at the bottom of the window for further

information regarding the error.

Creating Worksheets

Opening the workbase in step 4.1 creates an empty workfolder. A custom work‐

sheet for calibration and data viewing/measurement can be made by clicking

and dragging variables from the variable list to the worksheet area. Certain data

types can also be viewed in an oscilloscope; this can be done by right‐clicking on

the desired variable and selecting the option “New oscilloscope”. If you wish to

create multiple sheets within the workfolder, right‐click in the worksheet tab area

and select “New”.

Loading the Pre‐Made Workfolder

Included in the LT4 ADV project folder is a workfolder file with pre‐made work‐

sheets. These have been configured with the most important variables to enable

quick calibration and data viewing. To load this workfolder, select the tab “Work‐

folder/Worksheets” at the top of the ModasSport window and select the “Open”

button in the “Workfolder” section of the ribbon:

The “Open workfolder file” dialog should automatically open the folder “CON‐

FIG” within the LT4 ADV project folder. If this does not happen, navigate to your

LT4 ADV project folder directory and open the folder “CONFIG”. Once here, se‐

lect the file “LT4 ADV.mxwf”:

The worksheet area should now be populated and two worksheet tabs should

appear in the lower left corner of the area. The sheet “Monitor” will allow you to

monitor sensor status, sensor readings, and LT4 ADV communication. The sheet

“Parameter Settings” will allow you to perform calibration and device setup tasks.

Changing Calibration Values

In order to change calibration values in the “Parameter Settings” worksheet, the

working page must be loaded. To do this, select the “Start” tab at the top of the

window and select the button “Read data from ECU” in the ribbon. Once data has

been read, the working page can be loaded by selecting the button “WP”:

To change a value, double‐click the value, type in the desired new value, and

then hit the Enter or Return key. Some variables can be changed through drop‐

down boxes as well.

Once a variable is changed, an arrow will appear next to the value to indicate the

direction in which the variable was changed.

To write new values to the ECU, select the button “Write data to ECU” from the

ribbon under the “Start” tab:

Live Viewing of Measurements

To start live viewing, select the button “Start” in the “Measurement” section of

the ribbon under the “Start” tab (red box in the figure below):

If you are using the pre‐made workfolder and worksheets, measurements are

shown in the “Monitor” worksheet.

To record data, select the “Start” button in the “Recording” section of the ribbon

under the “Start” tab (green box in the figure above). Selecting this brings up a

prompt where a save location can be specified. To stop the recording, click the

“Start” button in the “Recording” section again. Recordings can be opened in

Bosch Motorsport’s WinDarab analysis software.

Firmware Updates

Should a firmware update be required for your LT4 ADV, you will receive files

with the suffixes “.A2L” and “.HEX”. The “.HEX” file contains the LT4 ADV firmware

while the “.A2L” file is a variable description file. These files should be copied to

the “CONFIG” folder in the LT4 ADV project folder (typically C:\Bosch\ModasS‐

port\LT4\CONFIG).

In ModasSport, click the circular menu button in the top left corner of the win‐

dow and select the option “Flash Tool”:

Fig. 5: Flash Tool selection and Modas Flash Tool window

The Modas Flash Tool window will appear. The following points describe the ac‐

tions to be taken for each parameter in the flash tool:

▪ HW Interface: MSA‐Box II

▪ Hex File: Click the “Select…” button and navigate to the “.HEX” file which was

moved into the “CONFIG” folder of the LT4 project folder

▪ Seed DLL: Click the “Select…” button to locate the Seed DLL file. This is also

located in the “CONFIG” folder. Usually, this field will populate automatically

as long as the Seed DLL file is in the same directory as the “.HEX” file.

Once these settings have been set, click the “Program ECU” button.

Notice Do not interrupt this procedure

It is very important that the power and communication to the LT4 ADV is not in‐

terrupted during this time. Do not disconnect the MSA‐Box from the computer

or from LT4 ADV and do not shut off power to the LT4 ADV.
