//Notes
The Z4's N20 engine came in three versions: 156, 184 and 245 hp. The owner wanted something mild and safe for the 20i, rated by BMW at 184ps and 270Nm.
We didn't load the 28i software; we made the matching changes to the 20i's own factory map. The result equals a factory 28i: 242ps with 350Nm of torque.
