uFCU for Wolf engine lithium Works great with the WolfuFCU for the Wolf engine. This item is a complete FCU, but in a "general" format instead of V2. It completely replaces the original V2 FCU board that is included with the engine. You will need to wire your own switches, or use a Perun triggerboard.
