Nano Identifies as TCU not ECU
Posted: Fri Feb 27, 2026 2:15 pm
Recently purchased nanoECU. Trying to get it set up only to find that TunerStudio could not see any of the I/O besides DC voltage.
Downloaded the latest release and it fails to install as the unit identifies as nano-tcu in the rusEFI console
The board itself appears correct as the screen printing for the pins includes INJ1, INJ2 etc. The PCB is printed 'hw-nano', 'dual-can rev. a'
How can I install the ECU firmware onto this unit to convert it?
The updater will not proceed to install ECU once it detects as TCU
