The mod is conversion of a EU Fxx 523i to a 528i. It is valid for cars of production period where both models were delivered with the same N53 motor, albeit the 523i being detuned in HP & Torque.

The mod requires a software change to the DME & EGS modules of the car, and a replacement of the Single-step intake manifold with a 3-Step intake manifold equipped by DISA valves.

This document details the software change segment of the mod.

Module software used is the same as the original delivered by BMW in MY51 N53 equipped cars.
