Which ECU Part Number should I choose?

To determine which ECU Part Number (Bin File Definition) to use for your particular ECU 
  1. Connect your harness and Interface to the ECU
  2. Connect the Interface to your computer via USB cable
  3. Put the Interface into Read/Write mode (Red LED on) 
  4. Go to "Tools"=>"Read Serial Number", this will read the ECU Part Number and Serial Number from the ECU. 
You will be able to see exactly which Bin File is in the ECU and use this Bin File as your starting point for further tuning.

Note: The Read Serial Number function is not available for all models of ECU, some of the Denso ECU's are not able to be read from the main ECU connectors, so the Read Serial Number option is not available. If this is the case you can determine which ECU Part number to use by inspecting the Part Number on the ECU (see below).

There are usually several ECU Part numbers listed for a particular model of bike.


The part number is made up of 3 sections:

Manufacturer Identifier: 
  • Suzuki: 32920-21H60_DJ0HSE00
  • Kawasaki: 21175-0082_F569146E 

ECU Part Number:
  • Suzuki: 32920-21H60_DJ0HSE00
  • Kawasaki: 21175-0082_F569146E 

Bin File Serial Number:
  • Suzuki: 32920-21H50_DJ0HSE00
  • Kawasaki: 21175-0082_F569146E

The Manufacturer Identifier and ECU Part Number are either stamped into the plastic case of the ECU or on a sticker on the ECU. The Bin File Serial Number is not visible externally, it is in the bin file inside the ECU.
