Suzuki K1-K3 GSXR 16bit ECU Engineering...


       

This site serves as a repository for various resources related to re-engineering the 16-bit GSX-R 600, 750 and 1000 ECUs. Although work has focused on the GSXRs, most of these tools are also compatible with the Hayabusa and other Suzuki models, and can be adapted to Yamahas and Kawasakis equipped with 16bit Denso ECUs. 

The initial discovery work on these ECUs was done with a custom (read-only) mini-BDM tool and required "notching" the ECU to access the BDM port. It was later discovered that these ECUs also have an ISO9141 OBD-II (K-line) interface wired to the harness connector, so all development has since been based on that interface (and no longer requires cutting into the ECU). If you're new to 16bit ECUs, a good place to start is the "BDM Utilities" and "OBD (bootloader)" sections to better understand what they are and how they work.

Unfortunately not all 16bit ECUs are flashable, so each unit has to be tested separately. If you're looking to test whether your GSXR or Hayabusa 16bit ECU can be reflashed via OBD, check out the "OBD (bootloader)" section. For the ZX12R, TL1000R and TDM900, see the "Other 16bit ECUs" section...

Hundreds of hours have gone into the development of utilities and information presented on this site. If this work benefits you or your business, then you should seriously consider giving something back. Whether it be sharing technical information, test results, ECU binaries, spare ECUs, RomRaider definitions or even a cash donation. Your contributions are vital to increasing the knowledge base and expanding the possibilities of what we can achieve with these ECUs...
