Hi again.......

Turns out the pump was much too dry after standing for years before I fitted it. The helpful fellow in Aquamist suggested a syringe full of water which did the trick!

Now my next issue, which ought to be simple for those in the know.....

My aquamist system is deployed on a Racecar 600BHP Diamond Turbo ALMS type engine with MoTeC M800. It has unacceptable knock at high boost so I am limited at the moment to around 1.5 BAR. I'm fairly happy that I can map WI to overcome this, but I'm concerned about a failsafe? I do have a 0-8v feed from the stop valve, but the voltage info I'm getting from it merely increases roughly in proprtion with the High Speed Valve pulses not when there is no pressure in the system.

What I need is something to tell me / the ECU when the waters run out - so I can set up an activation signal in the ECU to take away the power relay earth or something, and swop to a richer/less advance map.

A float is not really practical in a Race Car, but has anyone got a simple , cheap solution that is reliable enough to avoid a melted engine?
