[Diy_efi] Bosch LH Jetronic v2.2

[WSCowell at aol.com]

I have a Jaguar XJ40 ("XJ6") built in 1989 with the 2.9 litre engine.   This 
engine alone in the XJ40 stable uses the LH Jetronic system - the others  with 
the bigger inline six cylinder engines use Lucas systems.
 
It has two ECUs, one for fuel, the other for ignition.  I want to  understand 
much more thoroughly how these two interact and control the engine,  but 
cannot find any information anywhere so far.
 
Has anyone out there any info on these two units at all please?  I am  
looking for binary files, port/memory address maps, disassembled firmware,  anything 
that will help me understand how this engine runs, and what information  it 
sends to the proprietary Jaguar electronics in the instrument pack and so  on.  
The owners' clubs are no help, no-one there knows anything at  all.
 
Regards
 
Will Cowell
