lol OK thanks guys I asked the seller and he said it came off an 16v xr2i! Cheeky sod! I think ill just get an rs1800 ecu or mondeo 2.0litre ecu instead would they just plug and and work?

So list is:
2.0 ECU
2.0 TB
2.0 MAF
2.0 Cams

Should be 130+ bhp is that right. Got that info off fiestaturbo.com
