Introduction
ECU Bridge belongs to the last generation of AIM loggers for car/bike installations.
There are two available versions of ECU Bridge:
• K line/CAN version – with OBDII connector – for an easy and quick
Plug&Play connection to the vehicle OBDII plug (suggested for stock ECUs).
• RS232/CAN version – with free cables – for a straight ECU connection
through the serial/CAN communication protocol (suggested for both stock
and after market ECUs). Supported ECUs database is constantly updated.
Refer to www.aim-sportline.com “Download Area/ECU connections” for
further information.
ECU Bridge samples but does not record data out coming from the vehicle ECU; it can
show them if connected to an high technology AIM display like MyChron3 Dash, TGDash
and Formula Steering Wheel or to SmartyCam, the AIM on board camera the only one
with data overlay.
ECU Bridge manages 3 different communication protocols:
• K Line;
• CAN Line;
• Serial RS232 line.
Technical Characteristics:
• ECU interface;
• CAN protocol for external expansion modules;
• USB port for programming
• 8/18 V external power.

2.1 – How to power ECU Bridge
ECU Bridge needs a not stabilized 8-18 VDC power sources.
It is suggested to power ECU Bridge through the vehicle master switch to save the vehicle
battery charge.
Use an external power source to power ECU Bridge CAN/RS232 and connect ECU
Bridge free cable directly to it.
Use the vehicle lighter plug to power ECU bridge CAN/K Line: insert the Bridge lighter
plug in the vehicle one.

2.1.1 – Cable labelled GND
To correctly power ECU Bridge and for the signal to be stable it is recommended to
connect cable labelled GND coming out from ECU Bridge powering harness to thevehicle
chassis ground, as highlighted here below.
