Engineering render of the current CADE WMI Controller board revision. The production unit mounts in a sealed engine-bay enclosure.
Water-methanol injection only protects your engine while the spray is real — and most controllers just assume it is. The CADE WMI Controller is built around the opposite idea: progressive, boost-referenced injection with genuine flow monitoring, and a hard fail-safe output that pulls the engine back to a safe calibration the instant delivered flow doesn't match what's commanded.
The WMI-OK output is a dedicated hardware line to your ECU or a relay — wired so that a blocked nozzle, empty tank, dead pump or cut hose means reduced boost, not a lean engine on a methanol tune.
The first production-built units are on the bench now, with an updated USB-C revision already designed behind them. Register below and we'll let you know the moment kits are ready.
