Rev Limiter / Speed Limiter (brake lever code) 2-stroke scooters / mopeds

Digital speed / rev limiter with brake lever code and automatic reactivation

Main function:

The digital speed limiter (DZB) has a powerful microprocessor that continuously calculates and evaluates speed and rpm.

• The speed is determined by the wheel sensor supplied in conjunction with a small self-adhesive magnet for the rim.
• The RPM is calculated directly via the pickup cable of the CDI ignition with each piston revolution.

Operating modes:

KMH mode:

• In KMH mode, an upper speed limit is set.
• The limiter throttles the scooter by reducing the speed as soon as this limit is reached.
• A variably adjustable pre-stage enables a gradual reduction in speed shortly before the maximum speed for a smooth transition.
• Below the set maximum speed, the speed remains unchanged.

RPM mode:

• The wheel sensor is not required in speed mode.
• The RPM limiter only throttles the scooter via the adjustable maximum RPM.
• If the speed falls below the set limit, the limiter does not intervene to prevent a loss of power in the lower speed range.

Combi mode:

• The RPM limiter works simultaneously with the set speed and KMH limit.
• Particularly useful when a high revving scooter is to be set to a low top speed.

Programming and control:

Programming the top speed/maximum speed is done simply by pressing the internal button.

Deactivation:

• To deactivate the throttle, a 6-digit Morse code is entered using the brake lever.
• To reactivate, simply switch the ignition off and on again briefly.

Dimensions and installation:

• The housing is compact (45x45x18mm + mounting eyelet).
• The connection cables are 45-50cm long.
• The wheel sensor has dimensions of approx. 28x19mm, with a cable length of approx. 50cm.
• Installation is simple with 4 quick cable connectors.
• Installation requires the connection of +12V (switched via the ignition lock), brake signal, pickup signal and ground/minus.
• In KMH mode, the wheel sensor and the wheel magnet must also be attached to the front or rear wheel.

Advantages at a glance:

• Digital control of speed and rpm
• Stepless programming
• Adjustable pre-stages for smooth transition
• No power reduction below the maximum speed in KMH mode
• No power reduction in the lower speed range in RPM mode
• Automatic activation of the limitation
• Deactivation via brake lever code
• Individually adjustable brake lever code
• Quick cable connector for easy installation
• Best workmanship for increased durability

Scope of delivery and compatibility:

The scope of delivery includes the limiter, 4 quick connectors, wheel sensor with self-adhesive wheel magnet and detailed step-by-step installation instructions.

The module works with almost all 2T carburetor engines, such as Minarelli replicas (1E40QMB) like CPI and Keeway. However, it is not compatible with 4-stroke engines, direct injection engines, Morini engines and engines with double pick-up (e.g. Aprilia SR50 with brown and white cables on the CDI).
