Help on eproms

[George Theologitis]

Looking my car program with an eprom programmer, I want to know
how can I change pulses injectors timing, ignition timing and rev 
limiter. I'm working on Weber EFi (MC68HCP 11E1VFN) and on Motronic 
with INTEL 80.

Any help acceptable.
If anyone knows any site in the net, which can help me, please tell me.
