Sami:
GAMI is producing certified STC / PMA injectors for a number of
years... They have a large amount of engineering data from test
engines, and a huge base of customer recorded engine operating data out
in the field... This constitutes a database of real world engine data,
more than the manufacturers ever dreamed of recording and magnitudes
more than the manufacturers use to have an entire engine certified...
To certify an engine the manufacturer runs it on a test stand for ~200
hours, tears it down for wear measurements, and that is it; It's
certified...
A case in point is the ongoing Lycoming crankshaft saga... The customer
is LYCOMING's engine test stand... GAMI has recorded more test stand
and flight hours just developing their injectors than Lycoming has for
rest of the entire engine itself...

If GAMI injectors and LOP operation was lunching engines we would know
it by now ... If you don't like LOP operations then don't do them
and save your angst for something that is a real problem... Simple, eh
wot...
