As it works without water injection

Add race gas to nearly empty tank (fuel warning bell or approx 1/8 tank). Run the car a couple of miles to use up lower octane still in the lines and to make sure any still left in tank mixes well with the newly added race gas. Hit the HOM switch and run the car. A red LED will stay lit after hitting the HOM switch (informing the driver that HOM is on and working).

As long as the PCM does not see a signal from knock sensor that would imply that there isnt race gas in the tank, you can run on HOM for as long as you have race gas.

IF for any reason the PCM gets a signal from the knock sensor that would give the PCM reason to suspect that you DO NOT have race gas after hitting the HOM switch, the PCM will override the switch and default back to stock mode and the red LED would blink (informing the driver that HOM has been shut down by the PCM).

Using the HOM allows for more timing = more power = car faster.
