THESE MANUFACTURERS OFFER TUNING FOR GENERATION 4
SPEEDBOX
The manufacturer from the Czech Republic has gained experience in the production of tuning chips since 2014. Its modules are installed directly on the engine and are suitable for all Generation 4 engines from BOSCH. The latest development is the SpeedBox 3.0 B.Tuning with its own app for the BOSCH drives.
POLINI
The Italians are the only manufacturers of e-bike and pedelec motors who also offer tuning modules. For Generation 4 of the BOSCH drives, there are the High-Speed 2 tuning modules, which are installed directly on the motor and cannot be seen from the outside.
PEARTUNE
The Czech manufacturer builds tuning modules for the engines of many well-known manufacturers. They feature clever functions such as a chip lock, which is also built into the MSO 4.0 tuning module for the latest BOSCH engines. This allows the chip to be manually turned off and made invisible.
BADASS
E-bike and pedelec tuning from Lower Franconia. The so-called Badass Box is not installed on the motor, but is simply attached from the outside and works with all Generation 4 motors up to 25 km/h. The Badass Box 4 is one of the most innovative products on the market.
VOLSPEED
TLI Elektronik GmbH from Ehekirchen in Bavaria offers state-of-the-art tuning modules for BOSCH Generation 4 engines under the label "VOLspeed". No PC or smartphone is required for these modules; all settings can be made via the various displays. Another special feature is the "dynamic mode", which mitigates the so-called "wall effect".
WHAT TUNING VARIANTS ARE AVAILABLE FOR GENERATION 4?
At SIP Scootershop we offer the following tuning modules for Generation 4:
BOXES
These small boxes are plugged onto the sensor of the bike or pedelec and now this tool halves the transmitted speed, doubling the motor support. It is a wireless device that can be removed again in no time. The manufacturer Badass is the market leader here.
TUNING MODULES
These small boxes contain a chip, are installed invisibly under the engine cover and clamped between the sensor and the control unit. The module can even be switched on or off via the display while driving. The latest modules, such as the Speedbox B, also have integrated app control via Bluetooth. The control and also the reading of the motor data can be done with the smartphone. However, tools are required for installation and removal. In the following, we will go into more detail about these modules.
The motors are controlled by a speed pulse that tells them how fast a pedelec or e-bike is travelling. If the pulse reaches 25 km/h, the motor switches off. However, if only every second signal of the impulse comes through, 50 km/h can be reached, because the motor is "fooled" into thinking it is travelling at a different speed. With cheap modules, the speedometer then simply displays half the speed.
More sophisticated chips are more advanced: they halve the impulse only from 23 km/h or, in some drives, they are directly connected to the data transmission between sensor and motor, so that the speedometer always shows the correct values. The most modern tuning modules, for example from VOLspeed or Speedbox, even display the total kilometres driven and average speeds correctly.
However, the software version of the bike and pedelec must also be kept in mind. A carelessly installed update from the manufacturer can abruptly end the tuning pleasure. Be careful, because the motor manufacturers and tuning experts are constantly playing a cat-and-mouse game.
