I have had it in my Jalpa for a couple of years (not many miles though) and it is controlled by the TEC-3 unit based on software changeable coolant temperature level.
It works well, no leaks at all, but ... it just does not have adequate pumping capacity. Remember the flow characteristics are very different than a mechanical pump, which is rpm dependent only. It can deliver max flow at idle (good for city driving), but is inadequate on the track where many cal/sec (~ proportional to delivered HP) are produced and need to be removed.
I can only do 4 laps on Streets of Willow, before it gets dangerously hot. Even freeway driving on a very hot day is marginal. I don’t even think their EWP110 would be adequate on the track, but two EWP80 might.
