Are you sure? As I understand it, the Fuel sender only supplies the "Miles Left in tank" feature. The EEC has the Fuel Flow function that supplies the "Miles per Gallon" and "Avg Miles Per Gallon" features. I may be wrong but it seems to make sense that the EEC would monitor Fuel Flow as a Function of the O2/Fuel mixture.
What do you think?
By the way to the other guy who posted- Do a search and you'll answer your question above.
