I use an Aquamist 2c with a MoTeC M4. The 800 will be able to drive the High Speed Valve just fine.

You could set the M800 up with the 2c and use the digital pressure output with a digital speed input in usecs to get a reading of water flow, or better still add one of the flow meters and use that with an analog input.

You use the AuxV or speed reading to add a trim to your ignition, fuel and boost maps. I don't believe you can switch to a whole different map (can't in the M4 anyways) but the trim should work fine.

The net effect is if you run out of water, the trims come into play and pull timing and or reduce boost and or add fuel.

You probably want about 700cc/min capability so you'll be using two jets and two HSVs most likely, maybe a second pump depending on exactly what you want to do.
