Take care: Regarding new motor firmware versions for DUE50X0 and DUEP800 drive units released from Shimano Oct. 22, 2020 and Nov. 04, 2020.

On Oct. 22 and Nov. 04, 2020 Shimano has released new firmware versions for these drive units: DUE50X0 (4.4.2) and DUEP800 (4.1.1). We have released our Windows based miniMax program version 2.02 which is capable of modifying a bike with the newest firmware according to the USA – modification as well as according to the wheel – circumference – modification (down to its min. value of 1300mm). However, currently it is not possible to process these modifications with our eMaxMobileApp. So please do not update to the newest motor firmware if you intend to optimize your bike via Bluetooth.
