7D is a UK ecu i think.
U8,2C,W6 (will work but are 240ps)
Z5
6K

Z4 you should only pay about £60-£70 for but i've seen the ones on eay for over £100 (whoever is selling them is having a laugh imo)
What is wrong with your Z4?

well i put one of those scooby chips in it of ebay well just lately the car has been less than reliable so the missus broke down again today(just lost power and cut out)i went out and found her took the ecu you out took the chip out and connected the link again and the car ran again but just worried it might of buggered the ecu .
and i will miss the extra boost time for a remap me thinks or a decent chip

I wouldn't have thought it would bugger up the ecu as reconnecting the J1 resistor sets it back to default and ,imo, if their was a problem with the ecu it wouldn't work at all.
Worth speaking to Scott T at PolarPerformance as he normally has spare ecus and does sell chips for them (some people like them ,some don't).
He also offers the ESL fully remappable daughterboard (Enduring Solutions Limited has a full list of dealers)
