They are also multi-million dollar aircraft engine companies that

Yes, suddenly it's OK to run LOP when you give them $10K for their
FADEC.


That is because you have zero control over the fuel-air mixture, they
do.

Which isn't their argument now. They flat out say it isn't good for the
engine period.

That is correct, because you can't control the fuel flow to all cylinders
precisely enough.

Well, so lets put in $8000 for a FADEC instead of $1000 for GAMI's. Yeah,
that's a great deal.

The FADEC system will not allow the engine to run in an condition that
will cause damage. If a CHT is too high or EGT too high guess what
happens. It INCREASES the fuel flow to that one cylinder to bring it
down.

FADEC can't adjust one cylinders fuel flow.

It can also retard the ignition on that one cylinder only to correct the
condition. It never LEANS further to cool cylinders or EGT temps.

What a marvel of Rube Goldberg engineering.

So, are they going to increase their warranties from nothing to something
now?
