- Shimano EP801 and EP600
Shimano just dropped the 4.3.0 update for the EP801 and EP600 motors. I usually don't do articles about software updates, unless it’s something very interesting. The Auto Shift ver. 2.2 might be big news, it remains to be seen. The carry over settings definitely seem interesting.
This sounds well and good, but there is an asterisk*. These settings can only be changed in the Shimano Professional software, consult your shop/distributor to perform the changes. That will change with the next Shimano E-Tube Cyclist update though, which is expected sometime this autumn.
It seems the EP801 can be configured to resemble the Bosch Performance CX Race. And Racing is an important reason for this update. Yeti, Rotwild and the Orbea e-EDR racers have tested various motor- and autoshift settings in competitions. It's been over a year since autoshift was launched and it seems Shimano has decided how they want the autoshift and overrun to work on customer bikes.
Motor overrun settings for EP801
I just did an article and a video about overrun on the EP801. And I had to get it out quickly as there was a rumor about this new update.| ■ New functions have been added to the assist settings. ・ The "assist carry over function" has been added to the assist settings. This 3-level selectable function allows you to select the duration that assist continues after pedaling stops.* ・ The "assist cutoff function" has been added to the assist settings. This 3-level selectable function allows you to select when the assist cutoff starts near the maximum speed limit.* ・ An aggressive assist character has been added to the assist settings. The characteristics of the existing assist character Lv15 have been changed to be more aggressive.* *These settings can be changed on E-TUBE PROJECT Professional ver. 5.3.2. If you wish to make changes, please consult your place of purchase or a distributor. For E-TUBE PROJECT Cyclist, these settings will be available in the version after ver. 5.3.2. |

Overrun and autoshift
"Assist carry over" is the Shimano name for overrun and now there are three durations to choose from on the EP801. Next there's the option to set how hard the motor power ramps down as you approach the cutoff speed. This option is also available on the EP600. Finally, level 15 of Fine Tune mode has been altered to be more aggresive. It seems you can now configure the EP801 to be similar to the Bosch Performance CX Race motor. And racing is the motivation for this update. The Yeti and Orbea e-EDR racers have been testing various motor- and autoshift settings in competitions. More than a year after the introduction of autoshift, it seems they've settled down on new settings for both motor behavior and autoshift.This sounds well and good, but there is an asterisk*. These settings can only be changed in the Shimano Professional software, consult your shop/distributor to perform the changes. That will change with the next Shimano E-Tube Cyclist update though, which is expected sometime this autumn.
