[urq] Warm Up Regulator question

[Buchholz, Steven]

... it sounds as though you've verified the external interface ... the
only thing that would remain would be to look at the pressure vs.
temperature (and pressure) plots.  Here in the USA the P vs. T charts
are found in the "Bentley" manual ... i.e. the factory manual printed by
Robert Bentley ...

I am guessing that you suspect your CPR in your car and want to test
with the one from the KV.  My first suggestion would be to measure the
system and control pressures to confirm that they are correct per the
factory documentation.  If you find there is a deviation, it is possible
to adjust the control pressure.  You may find that you can make things
work without trying to make a different part work ...
