Luftmeister EFI for BMW Boxer twin Motorcycle

[Bob Moseley]

I have a "luftmiester" efi system which I bought s/hand at an autojumble. The 
ECU is stamped Haltech. I am not entirely sure it is complete. It has two 
sensors, one to a throttle body and one to a cylinder head. There are 4 three 
pin din type leads on the harness of which these two sensors are connected. What
are the other two for? How can I test the ECU. Fortunately the wires for power 
supply, the fuel pump and earth etc are labled so that should be OK.

Does anyone know of a Haltech supplier / distributor in the UK or have any 
practical knowledge of fitting such a system to BMW R100/7 boxer twin.

All help gratefully received.
