No idea, but he's a Bosch autocenter technitian, so I gave him the benefit of the doubt! Is that the map file and set up/config data file?

8 weeks, £400 & 3 ECU's later, it's sorted! A few pointers for people in future; - No EML on ignition - no squealing from Throttle body - No communication through Opcom - Loom of doom checked for permanent live, switched live, and earth on ECU checked ( from what I've traced, it seems to ground on the inlet manifold - ECU multiplug checked for perm and switched live As a precaution, I purchased a Z12XE ECU - this is the same hardware as the z20let ECU (£15 off eBay). I plugged that in and the EML came on, throttle started squeeling and could talk to the ECU in Opcom. Note that I wouldn't recommend starting the car on this ECU!
