Hi Pansy,
Welcome to F-150 Online!
You have an EEC-V ECU, as do all 1996 & newer F-150's.
It's highly doubtful that you will ever "modify" that eeprom yourself, as in addition to specific and expensive hardware and software that is required to be able to actually write to that EEPROM, you would also have to know all the addresses, etc. to control each function in the many thousands of lines of code. Given the hundreds of different codes used in these F-150's each model year alone, it takes a huge amount of R&D to know exactly what is really going on there, how to change it and what the result is, what is safe, etc., and that is not something that just anyone can just do on their own casually.
The eeprom in the Ford ECU is a surface mount, so it's not replaceable, cannot be removed, etc., unlike many of the old GM & Bosch ECU's.
From a pure program standpoint, these F-150's aren't like an old 5.0 Mustang that can be tuned by using just about any code, like an A9L, A3M, etc., which are easy (by comparison to these F-150's) to toy with for someone who actually has experience in powertrain programming Ford ECU's.
The bottom line is this is not a casual thing that anyone who can "speak" hex code can do, it's far more involved, for openers, you have to know what line of code at what address actually controls what, and how, what the complete address ranges are for that function, and so on...................
If you'd like to give us a call, we can go over some of that with you to give you an idea of what you're up against (so to speak), and also give you an idea of what we can do, as well as talk about just exactly what you're thinking, what you want to change, etc.
Good luck!
