MS42 ECU REMAPPING

⚙️ MS42 Remapped ECU – Ozworx Edition

Modern control. Aggressive tuning. No dead weight.

The MS42 ECU (found in M52TU BMWs like the E46 328i and E39 528i) offers a solid foundation — we make it better. Our remaps strip out the factory dead weight and push your engine to deliver cleaner power, harder pulls, and sharper response across the rev range.

Perfect for track builds, street sleepers, and RWD swaps where reliability meets performance.

🔧 Tuning Features:

• Optimised ignition and fuel maps

• Rev limit increase

• Speed limiter removal

• EWS delete (immobiliser bypass)

• SAP, rear O2, EVAP & post-cat deletes
  

• Burble / overrun options available

• VANOS timing optimisation
