SpeedBox 1.3 Tuning Chip for Shimano EP8 + E-Tube Port

SpeedBox 1.3 + E-Tube Port is the variant of SpeedBox 1.3 for Shimano EP8 e-bikes that do not have a free E-Tube port, usually those with Di2 electronic shifting or a Satellite System ON/OFF switch.

It removes the speed limiter, is switched on and off by turning the lights off and on, and the display shows real values up to 23 km/h. This version does not connect to the SpeedBox Connect app.
