I have been having problems with my 85 4k Quattro for about a year with it
running way rich at idle and too lean at cruise. I have tried everything
except swapping the ecu. I have a complete mc motor with the harness and
ecu. I am looking at swapping the mc fuel management system (mac 10 ecu,
fuel distributor, injectors and harness) over to the stock motor until I put
the turbo motor in. My question is which sensors besides O2, full throttle
switch and Idle switch are required if I only need the fuel side of the ecu
and will it work with the rpm and hall sensors not connected.

Thanks John
