[DeTomaso] How much has EFI advanced over the past few years?

[JFFR]

The FAST XFI 2.0 port injected system that I am using has a wide band 
oxygen sensor and two MAP sensors. One is used for real time barometric 
pressure readings. There is also a low oil pressure shut off, which I 
really like because I do track the car once in a while and like that 
added safety feature. It can do data logging and the on dash display 
tells you everything that is going on with the system. It has the 
capability of storing and using four different tunes. All you need to do 
is select the tune that you want before starting the engine. I haven't 
actually tried the feature yet, but it might be something that I may do 
in the future. My thought was to set up an economy driving program.

These aftermarket systems have come a long way in the last ten years, 
but the factories are staying ahead of them with their direct injection 
systems and cylinder deactivation. I will never go back with a 
carburetor on my Pantera and actually like the challenge of learning 
about fuel injection even at my age.
