Vortech Fuel Management Units (FMU)

When an engine is supercharged the air delivered to it is greatly increased. For the engine to run properly and make max power a 11.5:1 air/fuel ratio must be maintained.

Since the factory electronic controller can compensate for this increased air flow (it was not designed for supercharger use) another way has to be found to supply the necessary additional fuel.

The FMU is the device that does this.
