The VaporWorx Intelligent Relay Control (IRC) will provide convenience and safety features that will help protect you and your pride and joy. This system is easily adapted to both new and existing builds by controlling the negative trigger side of a standard automotive relay.
Electric fuel pumps, especially those used in carbureted engines, are usually powered by a relay that is turned on by the ignition switch. That means for as long as the IGN is on, so is the fuel pump.
But what if the key needs to be in IGN but with the engine not running?
What happens in case of an accident, the fuel line is ruptured, and IGN is still on?
Most modern ECM’s have priming and system shutdown strategies to deal with these conditions. When using IGN only to trigger the relay on, fuel may be pumped uncontrolled. This can be both inconvenient and dangerous.
The VaporWorx IRC uses the engine tachometer signal to sense when to operate.
