Fred,

Do You mean that the EFI is compliant with the ODBII standard?
I crashed a 1999 ST and I am rebuilding it to a naked bike. I will be rewiring 
the complete electrical system. It would be a great help if I could read out 
and reset the codes on the EFI. 

Following the guidelines on the scantool website the EFI should follow the  
ISO9141/14230 standards. Is this correct? Do You use the windows or the Linux 
software? 

Best Regards,

Marc de Vries

ST 1999, rebuilding it.
ST 2001 BRG, best bike ever made.
