Small engine, real EFI!

The engine computer for 1-2 cylinder engines such as motorcycles and karts: it controls fuel and spark, and you wire and tune it yourself. Inductive ignition only, not compatible with CDI.

  • Inputs: 1 VR trigger (no Hall), 5 analog

  • Dedicated tachometer output; SD card logging, CAN, USB-C for tuning

  • Enclosure included, color varies

Need wideband, knock or drive-by-wire on the board? See uaEFI.

Options

  • nothing: you source the 26-pin Superseal plug and terminals yourself

  • crimp kit +$10

  • crimped wires kit +$15 (no crimp tool needed)

Order 3, we ship 4. Ships from New Jersey, USA, usually within 5 business days.

Docs and support. Pinout and firmware: wiki.rusefi.com/nano. Help comes from the community: forum, Discord, Facebook group. One-on-one help is sold separately as Technical Support.
