Hi

I am in the process of modifying my Lancia Integrale and having
altered several parts of the engine i.e raising the turbo boost
mechanicaly,flowing the head,replacing the Map sensor,fiting
free flowing exhaust etc. i have reached the stage where i need
to reprogram the eprom according to my own specifications.
I have been going throwgh the eprom data for a long time,but
i have not yet been able to find the specific locations of
fueling,advance maps.
Is it possible that the eprom contains both the maps and the
operation programm of the ECU or does it contain only the
maps?
Could you,please,give me some clues as to how to identify
the maps and how to understand the use of each map individualy?
Furthermore,the boost pressure is controled by the ECU which
means that the eprom contains hex numbers on the basis of which
pulses are created on an electromagnetic bleed valve which 
increases or decreases the indication of the pressure in the
wastegate diaphragm,thereby,controlling the pressure.
There must be a map reffering to the above,thereby,controling the
pressure according with the engine LOAD,engine RPM and the 
position of the throtle.
Could anyone,please,help me find the exact location of the map?
I will send the eprom data in UUE format named 'LANCIA.UUE' in
another mail for your convenience.
In case none can help me with my specific problems,is it
possible for you to steer me to the right direction for my quest?
My car is a Lancia Integralle Evo III 16V model '94 with catalytic
converter.
The ECU is WEBER-MARELLI IAW 4WG 274 93
The microcontroller of the ECU is MOTOROLA MC68HCP11E1VFN

Thanks in advance
