All ECUs have a unique part number which can be used to tell them apart from each other. When writing to an ECU it is important to always write a bin file which matches the part number. This ensures that the ECU is only ever written with data that is compatible with the intended vehicle.
Some ECUs have the part number written directly on the label (especially older ECUs) but many others (eg. 2020+, especially Denso ECUs) do not show the ECU part number at all on the casing or they show a generic number which is NOT the real ECU part number. This means that we need to find the ECU part number by reading it from the ECU directly with the Woolich Racing Tuned software software.
This article relates to Suzuki ECUs where a generic ECU Part Number is printed on the label on the ECU housing.
Since about 2020 Suzuki has released several bikes with ECUs that have generic part numbers printed on the labels like the one in the image shown below. Historically the Suzuki ECU part numbers have always started with "32920-", where the 32920 refers to Suzuki as the manufacturer. More recently we have seen many new and different ECUs with the same number printed on the sticker such as the one shown below.
These part numbers printed on the labels may include the following:
- 32990-10L0
- 32990-10L1
- 32990-10L2
- 32990-10L3
- 32990-10L4
- 32990-10LA
- 32990-10LB
Note that these numbers are NOT the ECU part number! The ECU part number is written inside the ECU so we need to use the
Woolich Racing Tuned software to read the real ECU part number as detailed in the following steps:
- Click on 'New' in the Woolich Racing Tuned software to open the Model Selector window.
- Select the Manufacturer/Model/Year and choose any part number as shown below for a 2022 Hayabusa.
- Click on 'New' to open this bin file and return to the main window.
- Do not write to this ECU!
- Select 'Tools' > 'Read Part Number and Serial Number' (as shown below) and follow the prompts in the software.
The software will do one of two things at this stage
- You may receive a message that the ECU part number doesn't exist in the Woolich Racing Tuned software. In this case the ECU needs to be physically sent to Woolich Racing to be read out and support added to the software, and you would need to Open a new Support Ticket.
- If the Woolich Racing Tuned software finds the matching ECU part number already in the software, it will ask you whether you want to open a stock bin file matching this part number. At this point you should click on 'Yes' to confirm and you can start tuning as usual, and you will be able to write to the ECU.
