EPROM Programming

[Len Sabatine]

  There's NO silver bullet for getting a specific system calibration "right 
on" other than
  hard work and attention to detail. Ever wonder why OEMs have so many 
different
  calibrations on seemingly identical equipped vehicle ? The devil is in 
the details,
  emulators just help to get them done quicker , working with old 
technology Eproms,
  which eat lots of valuable time in the erase and write process. It's not 
difficult to see
  why most devices use "Flash" now. On commercial programs , they are just 
that ,
  mostly fits all calibrations. Want yours to be right on , you've got to 
invest the time
  it takes to make it work the way you want. There's folks that do 
good  calibrations,
  and it's worth every $ they charge for the service , but you must seek 
them out, they're
  too busy to be telling you I'm the greatest, just ask me thing.
