Dinan Performance Engine Software unleashes more power from your BMW Z3 M by re-programming the fuel mixture and ignition timing parameters of the engine management system. Significant gains are also achieved at part throttle making extra power available where you spend the bulk of the time driving. Throttle response is improved through re-calibration of the drive by wire system. The top speed governor has also been effectively eliminated, enabling the vehicle to achieve its natural top speed.


  • More Power: Max gains of +14 HP @ 7500 RPM and +9 lb-ft TRQ @ 7500 RPM
  • 50 State Emissions legal; CARB EO # D-176-26
  • Improved throttle response
  • Top speed governor removed
  • Smooth and predictable power delivery
