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 Denso v2, Log Box Denso v2 and Log Box Pro Denso v2 interfaces as shown below.
On the "Tools" menu there is an item for "Test Interface", this allows the basic interface communications to be tested.
To Test Flashing Mode
1. Ensure the interface is NOT plugged into an ECU.
2. Put a jumper wire from pin 3 to pin 7 on the interface.
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 (red LED on).
5. Open the Woolich Racing Tuned software, go to "Tools" then click on "Test Interface".
Voltage Tests on Denso v2 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 (red LED on).
3. Measure the voltage between pin 4 and pin 8 on the interface, this should be 4.5-5V when in flashing mode (red LED on).
4. Measure the voltage between pin 1 and pin 8 on the interface, this should be 4.5-5V when in flashing mode (red LED on).
The plug pin out above is the 8-pin Molex socket on the Interface.
