EFI with 68HC11

[Georg Siotis]

Hello out there!
Is there anyone who has disassemble tools for the 8051/8048 family of 
processors that Bosch Motronic uses. I have heard that there a program that 
can show you the duty-cycle curves for the injectors, the timing etc, when 
you just read the program from an EPROM. Then you can modify the settings 
and burn a new EPROM. Can this program be bought somewhere? Are there any 
other techniques to cope this problem?

Thanks in advance
