   I need to update a reply I made re. engine durability in
the B17. It seems that there are TWO bytes which affect the
limits to which an engine can be pushed before it begins to
lose power.  First, as I originally stated, byte 0019
(debug119) has to do with the "toughness" of an engine.  It
is a relative value with that of the B17 being the lowest at
"98" and that of the P47 and P38 being the highest at "DC".
Hence, you can increase the stamina of an engine by raising
the value at 0019.
   The second byte that affects an engine's wear is 0017
(debug 117).  This byte is the engine thermostat that
measures the oil and manifold temps. and pressure as shown
on the guages.  This is also a relative value.  The value
for the B17 is "A0" is the highest among the planes, while
that of the ME262, ME163, GO229 and HE162 are the lowest at
"80" (the rest are all "C0").  Lowering this number has the
effect of adding more coolant to the engines.  I ran a test
flight with the B17's engine value at default (0019 = "98")
and lowered the temp/pressure byte to "00".  I pushed the
engines to 100% and ran a tank of gas and the guages never
moved.  I went back and set the temp/pressure byte to "FF"
and ran the same test.  The guages went red line before I
ever got the engines to their max. and the engines smoked
out in less than 5 minutes.  Don't know how this info will
impact the accuracy of other mods, but hope it helps.
