To connect the ECU to a PC, using a standard DB9 female connector, pin 32 (ECU TX)
of the ECU must be connected to pin 2 of the DB9 and pin 7 (or other Power GND
pins) of the ECU must be connected to pin 5 of the DB9.
To communicate with the PC ECU Fuel Trim (pin 1) and Ignition Trim (pin 26) inputs
must be hold at a voltage other than zero; this procedure enables the “Byte Mode” and
allows the ECU to communicate with EasiMap Windows tool (the MBE configuration
program – see ECU manual for more information).

9 1.2 – ECU Configuration

In order to communicate with the data logger, the ECU must be properly configured
using “EasiMap” software supplied with the ECU.
NOTE: data logging feature configuration with EasiMap v5.0 software is intended for
expert users only; See MBE site: http://www.mbesystems.com/index.html
1 Connect the ECU to a PC with EasiMap 5.0 installed, and turn the ECU on [ECU
pin 13 at 12V and ECU pin 6 (or other Power GND) at GND].
2 Launch EasiMap 5.0 software; choose [Get Data…] option from [Data] menu.
3 In the window [Select Parameter] open [Data Logging] directory and select [Data
Logger Link]; choose [ECU Device] in [Data Source] options and then press [OK].
4 Now the program reads information from the ECU and opens a new window to
configure the communication.
5 The parameters must be configured in the right sequence and with the right
scaling in order to communicate with the AIM data logger:
Data Logger Link: choose [Transmitting at 19200]
RPM: choose [4,00]

Parameter Scaling
1: choose [Engine Speed] Choose 16 bit
2: choose [Ignition] Choose 8 bit
3: choose [Injection Time] Choose 16 bit
4: choose [Throttle Angle] Choose 8 bit
5: choose [Coolant Temp] Choose 8 bit
6: choose [Air Temp] Choose 8 bit
7: choose [Baro Pressure] Choose 8 bit
8: choose [Lambda] Choose 8 bit
9: choose [Ri] Choose 16 bit
10: choose [Engine Oil Pressure] Choose 8 bit
11: choose [Fuel Pressure] Choose 8 bit
12: choose [Water Pressure] Choose 8 bit
13: choose [Engine Oil Temp] Choose 8 bit
14: choose [Gearbox Oil Temp] Choose 8 bit
15: choose [Boost Pressure] Choose 8 bit
16: choose [Gear Position] Choose 8 bit

When all parameter are configured, press [Send] button and choose [ECU Device]
when requested; configuration is saved in the ECU memory.
Close configuration window and quit the program. Before connecting ECU to the Data
logger, enable “Broadcast Mode” ensuring a nominally zero voltage (or open circuit) on
Fuel Trim and Ignition Trim inputs.

10 1.3 – Connection with AIM Data logger

7 8 – MBE 998 CAN

35 8.1 – CAN Communication Set–up

The ECU is equipped with a CAN communication interface used to communicate

parameters to an external data logger, or to configure the ECU itself.

36 8.2 – ECU Configuration

In order to communicate with the data logger, the ECU must be properly configured
using “EasiMap” software supplied with the ECU.
NOTE: data logging feature configuration with EasiMap 5.5 and EasiMap 6.0 software
is intended for expert users only; See MBE site: http://www.mbesystems.com
1 Connect the ECU to a PC with EasiMap 5.5/6.0 installed, and turn the ECU on.
2 Launch EasiMap 5.5/6.0 software; choose [CAN Datastream] option from [Data]
menu; then choose [setup].

EasiMap 5.5

EasiMap 6.0

3 Now the program reads information from the ECU and opens a new window to
configure the communication.Complete the table with the information suggested
in the screen below.
4 Parameters must be configured in the right sequence and with the right scaling in
order to communicate with the AIM data logger:
In this case configuration requires also the 998 Traction Control scheme:

When all parameters are configured, press [Send] button and choose [ECU Device]
when requested; configuration is saved in the ECU memory.
Close configuration window and quit the program. Before connecting ECU to the data
logger, enable “Broadcast Mode” ensuring a nominally zero voltage (or open circuit) on
Fuel Trim and Ignition Trim inputs.

37 8.3 – Pinout

- Pin 7 CAN low has to be connected to logger blu wire labelled CAN -
- Pin 6 CAN high has to be connected to logger white wire labelled CAN +
