After having my car for a couple of weeks, i realised it doesnt cut out over 10psi. Jap spec 1989 series 5 turbo. But i couldnt find a Fuel Cut Defender so i took apart the footwell to have a look at the ecu. The ECU just looks like a stock one, but it has a wierd black box hanging off the side of it, with wires plugging into the ecu, and then wires splicing into the factory loom. I drew a dodgy little diagram to try and describe it. Is this normal? If not, has anyone seen it before and if so, wtf is it!? The car also runs quite rich...

thanks for any help

Sounds like an FCD.
