MS43 ECU REMAPPING

🔌 MS43 Remapped ECU – Ozworx Tuned

The brain of your BMW, reprogrammed for raw performance.

The MS43 ECU (used in M54 engines like the E46 325i/330i, E39 525i/530i, Z3, Z4 and others) is a solid unit — but from the factory, it's holding back real power. At Ozworx, we remap it to unlock sharp throttle response, smarter fueling, and harder pulls all the way to redline.

No fluff, no bloat — just the control and aggression your build needs.

🧠 Tuning Features:

• Custom fuel & ignition mapping

• Rev limit raise 
  

• EWS delete (immobiliser bypass)
  

• SAP, EVAP, rear O2 sensor deletes

• Hard cut limiter & launch control (on request)

• Pop & bang / overrun burble optional

Perfect for drift setups, track builds, or street cars that don’t play by the rules.
