Motronic Question - Pin Outs

[Franz, Paul]

Hello;

I have received a heavily re-programmed Bosch Motronic M1.0 (similar to an
M1.3)  This was used on the BMW 1988 M3 but has been reprogrammed via a
previous owner for a different application.  The Motronic has a 35 pin
connector.  

Oddly enough the system used 2 pins which are not documented in any of my
references.  

Pin 18 of the connector is a tied to ground.  
Pin 32 of the connector is tied to a separate connector which tied it to a
separate control module which has ceased to operate.  Any idea what Pin 32
is tied to within the Motronic?

I am interested in pulling the binaries out of the Motronic,  any hints at
software which can reverse compile the executable to determine the changes
use in the aftermarket unit versus the original Motronic? 

Franz
