The failsafe has a 0-5v output that you wire into your ecu the same as a flexfuel sensor/kit would, and when failsafe is triggered it will send a signal to the ecu and your tuner will setup the integration into the tune to have it automatically switch the tune to compensate if failure triggers. IE by adding more fuel, and pulling timing and/or reducing boost. Also the flow gauge tells you precisely when/if and exactly how many CC/min you are spraying as well to make it easy to verify and properly determine nozzle size.
The failsafe will trigger when flowing outside of your set CC/min flow range, pump failure, any electrical issues, wmi controller issues, clogged nozzles, leaky lines, or low fluid etc… pretty much any issues that could go wrong it can detect and automatically adjust tune (if tuner sets up in tune) to be safe if the system malfunctions/fails.
It also has a small light i always install by speedo cluster that will blink/flash indicating a failure, the WMI cc/min flow gauge will also flash. And they flash in various sequences to indicate which of the various failures where triggered.
This allows you to tune more aggressively without concerns.
