SpeedFun Furious Ultra Specialized Gen4, 3.1 variklis

This Speedfun tuning kit removes the 16mph (25km/h) speed limit, allowing the motor to help you at higher speeds. With the speed limit removed, 28-37mph (~45-60km/h) can be expected, depending on the bicycle and gearing.

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

The function of the Furious Ultra tuning device for Specialized 3.1 motor (Turbo Levo gen4) is to electronically manipulate the rotation speed of the rear wheel and to communicate to the motor a speed always lower than 25 KmH in order to obtain a real speed with very high active motor. The maximum speed limit will therefore be dictated by the power of the engine added to the power expressed by one’s legs.

When the tuning device is active, having no communication with the display, it will show the halved data on any display (or app) starting from a certain threshold.

This tuning kit can be installed on Specialized Turbo Levo (gen4) equipped with Specialized 3.1 motor and MasterMind T3.

Furious Evo Ultra devices offer a choice of operating modes:
– Always active, cannot be deactivated
– Activated/deactivated by pedaling with the wheel lifted
– If tuning was active before turning off, it will also be active after turning it back on.
– If tuning was active before turning off, it will be deactivated after turning it back on.
– Tuning can be activated/deactivated with an external button (not included in the kit).
For more information, see the instructions on the page.
The device is supplied plug and go ready to use and is installed in a very simple way thanks to the compatible connectors with which no physical modification of the ebike is necessary.

WARNING!
This device is not compatible with Specialized Gen1, Gen2, or Gen3 e-bikes equipped with TCU01 (blue LED), TCU01 (Mastermind), or TCD. This device is not compatible with Specialized ebikes equipped with motor-controlled electronic shifting.
