Woolich Racing provides hardware and software solutions for writing tune files to the ECU, thereby modifying the vehicle performance. This all relies on our Woolich Racing Tuned software being able to communicate with the ECU via a Woolich Racing communication interface like the Log Box or USB. If there are problems with communication it is important to be able to quickly test the interface and its basic functions.
This guide explains how to test the USB M v3 and Log Box M v3 interfaces for Mitsubishi ECUs.
On the "Tools" menu in the Woolich Racing Tuned software there is an item for "Test Interface", this allows the basic interface communications to be tested as described below.
Note: The following only applies to the USB M v3 and Log Box M v3 interfaces for Mitsubishi ECUs as shown below.
To Test Flashing Mode
1. Ensure the interface is NOT plugged into an ECU.
2. Ensure you have powered the interface with 12V DC connected to pin 5 and Ground connected to pin 8 of the Molex connector.
If you have a bench harness to suit the Mitsubishi interface you can connect the 8-pin Molex connector and power supply as shown below.
If you only have a power supply you can connect to the interface as shown below.
The plug pin out above is the 8-pin Molex socket on the interface.
3. Connect the USB cable from the interface to the computer.
4. Move the mode switch on the interface to the right hand side position to the Read/Write mode.
Note: The v3 interface may not show the red LED until 'Test Interface' has been started.
5. Turn on the power supply.
6. Open the Woolich Racing Tuned software, go to "Tools" and then click on "Test Interface".
Voltage Tests on Mitsubishi v3 interfaces ONLY
Use a multimeter in a DC voltage setting to perform the following tests.
1. Connect the USB cable from the Interface to the computer.
2. Move the mode switch on the interface to the right hand side position to the Read/Write mode.
3. Connect the interface with a 12V DC power supply either using the bike ignition with an on bike harnesses or with the 12V DC power supply using a bench harness connected to the 8-pin Molex connector. Ensure the interface is NOT plugged into an ECU.
4. Turn on the power supply.
5. Open the Woolich Racing Tuned software.
6. Select and open a bin file that uses a Mitsubishi interface (eg. USB M v3 or Log Box M v3).
7. Click Read or Write ECU and measure the voltage between pin 3 and pin 8 on the interface, this should be 11.5V-13.5V when in flashing mode (Red LED on).
8. Click Read or Write ECU and measure the voltage between pin 4 and pin 8 on the interface, this should be 14.0V - 16.0V when in flashing mode (Red LED on).
The plug pin out above is the 8-pin Molex socket on the interface.
