# Shimano e-Steps
This repository is dedicated to the Shimano e-Steps as I happen to have an e-Bike that is fitted with the Shimano drive-train. There is hardly any technical information on the electronics, so I decided to do a little exploring myself.

Among the pedelecs, drive-trains of Bosch, Shimano, Bafang and Yamaha are used as well as automatic transmission systems of Shimano, NuVinci, etc. which make riding a bike a joy.
## Speeding up the e-Bike
Somehow we always are looking to get close or beyond the boundries that are set. In a case of a pedelec it would be interesting to go beyond the 25km/h speed limit. Doubling speed is dangerous, however setting the limit to 28 or 30km/h would be nice.
In the software the circumfence of the wheel is all that needs to be set, but where...

So far all experiments turned up nothing and are a bit frustrating.

### SM-PCE1 PC Linkage Device
The `SM-PCE1` is an USB interface to connect the e-Steps system to a PC. It is used for service, configuration and maintenance. It is normally not required for a bike owner to have such an interface, but my curiosity was triggered to find out if I can hookup Bluetooth to my bike.

Strangely enough the PCB has two super-capacitors. These are 2.5V and stacked so they can handle 5V.

### EC-E6000 Power Supply 42V @ 4.0A
The power supply is not just a regular power supply, but comes with a lot of electronics, including a micro-controller that talks over the power line. For the curious user you will find pictures that show the various parts of the power supply.

#### micro-controller
The micro-controller on the Power Supply board is from [SinoWealth](http://www.sinowealth.com/en/softtype.asp?cat_id=32&class_id=110). It is a 8051 class processor with some standard integrated peripherals.
## Tools
There are several companies and people who offer all kinds of hacks to speed up the pedelec. Clearly that is against what is legal: a pedelec has a maximum allowed speed of 25km/h and speeding it up beyond this point is a violation. If you want speed then use an e-Bike.
### YouTube
You can find hacks on YouTube that decrease the rotation of the magnet along the sensor by a factor two. The bike electronics controller thinks it rotates slower (half the speed) and increases its support effectively towards 50km/h (in theory).
### Shimano
As already mentioned Shimano has its own support software that works with their special interface.
### eMax-tuning
Another company [emax-tuning](http://www.emax-tuning.com) provides software for the Shimano **e-Steps 8000**. They also provide some freeware that can be found [here](tools/).
