Lucas EFI ECU

[Roderick Warner]

Is there anyone who has or knows where to get hold of a schmatic ( and ideally
some notes ) for the Lucas ECU as used on the Rover V8 engine. The ECU in
question is part # 83986A for the flap type air flow meter. Similarly if there
is experience of failure modes I would be very interested as I am in the process
of fitting injection to a previously carb'd engine and am suffering very rich
running , its ok when bliping the throttle. When I move the air flap( by hand)
it appears to have no effect on the running , though the voltages do change over
the specified range- hence I suspect the ECU. I need to get a scope onto the
pulses to see their duration and changes ( if any). Any thoughts please ?
