I did some research looking into the E90 with the N52 and the E87, they have the same version of ECU as the Z4's. But the N52 was used in many different cars so the ECU might vary.

Ecu hardware are same for n52 but map settings must differ considering the weird idle I had only begun after the tune. Either way just happy I got my car back although I missed the last month of track season.
