	Bruce,
	Only testing I've done is run the same car, same timing, same gas, same
jetting (I know this is an EFI list) at same ambient temp with different
value thermostats.
	Observations are a DRASTIC change in *audible* pinging under same driving
conditions with each change in thermostat temp.
	This is a thousand-dollar driver, not worthy of serious R&D or any dyno
time.  I do understand that any EFI system would incorporate other factors
not considered here, but I take my findings into account when tuning this
car..
	Gotta word things extra-carefully after the 180* crank fiasco a while back...
