Dinan Stage 4 Performance Engine Software - 1998-2000 BMW Z3M
$249.95
Stage 4 Engine Software is for use with the High Flow Cold Air Intake, Throttle Body and Air Flow Meter, ensuring optimum performance and drivability. Dinan Performance Engine Software unleashes more power from your BMW E36/7/8 Z3M by re-programming the fuel mixture and ignition timing parameters of the engine management system. Furthermore, the software safely raises the rev-limit, giving your BMW a broader power band and greater road speed potential in each gear. Significant gains are also achieved at part throttle, making extra power available where you spend the bulk of the time driving. The top speed governor has also been eliminated, enabling the vehicle to achieve its natural top speed.
Features:
- More Power (with intake, throttle body and air flow meter): Max gains of +38 HP and +29 lb-ft TRQ
- 50 State Emissions legal; CARB EO # D-176-13
- 200 RPM rev-limit increase
- Improved throttle response
- Top speed governor removed
- Smooth and predictable power delivery
Not compatible with the Z3M (E36/7/8) from 2001-2002. Dinan Cold Air Intake System, Throttle Body, and Air Flow Meter are required in order to run the Stage 4 Performance Engine Software.
