Re: carb vs. injection well over 10000 feet
That's the beauty of the ECM controlled injection system, it senses the amount of incoming air though the engine using MAF of MAP sensors. And then the O2 sensor in closed loop.
When they were using injection at the drag strip years ago, they had a shoe box full of injectors. If there were changes in temperature, humidity or barometric pressure, they had to change jets, that why that old Corvette system failed. With the computer and it's sensors, it makes the adjustments to compensate.
And where is it 2300 ft high in KS? I'm at 700..
