DINAN STAGE 3 PERFORMANCE ENGINE SOFTWARE - 2001-2002 BMW Z3M

Stage 3 Engine Software is for use with the Free Flow Exhaust and High Flow Cold Air Intake/Air Mass Meter Assembly, ensuring optimum performance and drivability. 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.
