Please see the sections below for the MEMS 1.3 ECU
The Android app works with MEMS 1.3 ECUs while using an appropriate cable.
The cables are full size USB so you will likely need to buy an "OTG" adaptor that fits between your device and the USB cable.

In case you are a programmer or would like more info about communication with the ECUs for diagnostics, here it is
Connect at 9600 Baud rate, 8 bits, 1 stop bit, NO parity
"Normal" serial communication - ECU has a TX and RX pin, plus a signal ground
