Anybody know what this thing is?  It's a small black box with a multiplug 
coming from it and spliced into the car wiring loom (I can't be bothered to 
trace which wires it's spliced to exactly).  There's a sticker on the front 
which has 4-injector, 6-injector and 8-injector tick boxes - naturally on my 
engine the 4-cylinder one is ticked.

If you've got broadband then take a look at the photos (170-230KB each):

I've no idea what it does but if I disconnect it the engine cuts out.  It's 
definitely *not* a Rover original fit!

There is also evidence of a circular hole about 3" diameter in the LH rear 
quarter panel which has since been filled and resprayed (badly).  I suspect 
this engine may have had an LPG kit fitted at some point and then removed. 
My question is; if it was part of some LPG kit what does it do?  Also, why 
does my engine cut out with it disconnected???

you could try uk.rec.cars.fuel.lpg

Its an injector emulator. When the car is switched over to LPG, it
disconnects the injectors while fooling the ecu into thinking the injectors
are still connected. If you wish to remove it, you need to find out where it
has been spliced into the injector wiring, remove its wiring and rejoin the
original wiring.

I thought that might be the case, though I'm puzzled why it'd still need to 
be connected for the engine to run now there is no LPG kit.  Would there be 
any performance/economy advantages in removing it and reconnecting the loom 
as per spec, or is it not worth the effort?

Good idea.  I'd forgot to check for other NGs which might be relevant.

There's a bunch of them on the 800 group with lpg, especially see bernard, 
he works with it.

Because when it is installed, the wires to the injectors are cut, and only
joined up again by the device. disconect the device and the injectors are
disconected.

No.
