E Bike Tuning: Shimano Steps E8000 Di2 öffnen / Abdeckung entfernen


Dear e-bike tuner, what you see is a Shimano Steps E 8000 motor, which I will lay bare now in order to reach the cables and insert the tuning chip. That is very easy in this case. You need a 2.5 mm hexagon wrench and unscrew these three screws here. Now I cut these cable ties. Take care not to cut the cable. And now you can see three plugs here. This is from the speed sensor, this one down here goes back to the electronic gear change. There are these strange plugs, DI plugs. Then there is a plastic part and you plug this in here and pull this out. It looks like this. The plug for the speed sensor has something like a “nose” here. This “nose” tells you that this is not connected to the bus of the e-bike. Then the cable is removed here. Now you have the display cable, which has no “nose”. It is a normal plug, a double-pole plug, which means you have the “plus” in here and the “minus” out there. And there the DE gear change, also connected to the bus, that means you can see on the display, in which gear you are at the moment. Through these two connections, the display and so on is supplied with voltage, at the same time, data is sent, which means it is a special bus. Now I plug this in again, which results in a click. Then the speed sensor. What you have left is the connection to the light, you see it here in the front. Just two screws, you can easily insert every cable, and then clamp it here. This is better solved than at the Bosch, because there you need extra plugs, but here you can connect every 6 volt light. On the right is plus and on the left minus. The only thing you’d have to do is to activate the connection for the light, but this can be done with the App “E-Tube”, so you don’t have to go to the trader. In addition, there is a programming tool for Shimano, which costs 140 Euro, with which you can activate the light or do firmware updates. You don’t necessarily need this tool. Thanks for watching!
