Re: Bosch CSI

[Mark Denovich <mark@domain.elided>]

I believe all Bosch injected Alfas are either L-Jetronic (GTV6, Spider, 
Milanos) or Motronic (164, later models.)   The L-Jetronic systems are 
not "chippable", but aren't fully analog either.   Replacement ECUs are 
availible, modifications made by changing internal resistor values and 
possibly other mods.  No one has published a how-to, and starting from 
scratch would probably involve a lot of trial and error.

The end result is that L-jetronic systems are a bit of a dead end as far 
as modifications go.   You can tweak them a bit with larger AFMs and 
maybe higher fuel pressure, but that's about it.
