It has to do with the design architecture and the biggie duty cycle employed by those Ford Engine engineers...
Yup, a hose, but it says something to a techie like me...
The thermal dynamics of the design has it very close to the thermal rejection design. Not much is left for it to go into a shallow hysteresis curve to allow the thermal sensors to come up to speed and set any one of the limp modes (most limp mode set points (both hardware and software) are based on thermal...both rate of change and ultimate temp)
Meaning that the thermal rejection systems was balls to the wall most of the time...maybe all the time and once the hose let go...no time for the system to warn...go into limp mode...shut down...
Duty cycle and is what Turtle talks to all the time when someone says why don't they put the F150 EcoBoost into the higher class trucks...LOL when he says that 2.x liter is really a 7L-8L when at full boost...lost to most that fine, but biggie point...
