I think the point of errant limp home mode or truly a problem is lost on you. With an airplane engine you want power until it shells out. You want power to save you. You don’t care about the wreckage, you want to live. If the pilot sees reduced power will save him, his hand can reach up and throttle back. If full power for 2 minutes will save you, you blow it up. If you are flying over high terrain and weather keeps you from turning back and then your engine goes limp home, you choice to fly into the mountain is made for you. Full power for ten more minutes might be all you needed. You are not going to crack the code to turn it off. You probably will not even be able to toggle manual gearbox without a full chip burn. Minor programming tweaks like a chip just shift the data. It’s not whole new programming. When my Toyota truck goes limp home, it will not go 40 miles an hour. The limp home is hurting everything more than the emissions code that triggered it. That stuff can’t be an option on an airplane. If you could toggle it he mode that GM has where you can drain the coolant and drive 100 miles, that would be cool. But it would need to be in a switch not automatic.
