The ECU in the Eagle Talon cuts both fuel and spark to *all* cylinders
at rev limit and has a hysteresis of 200RPM (cuts at 7500, re-enables
at 7300).  It also does this same fuel cut when the fueling limits
have been exceeded (i.e., too much airflow).

The ECU is pretty anal about not fueling a non-sparking cylinder.  It
can determine when one of the drivers that controls the FETs that
control the coils fails and will let you limp along on two cylinders
while not fueling the other two cylinders.
