Nano Identifies as TCU not ECU

Post by sort-it-out »

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

I have made a mistake - I've shipped you the wrong board.

"dual" does not have dumb coil outputs, I would have to ship you proper board. Sorry. Please DM or Discord me order info.
