Note: Values here are for a 32KB (padded) binary file. The stock binaries are 16KB and contain the same addressed, except in the first 4000hex (instead of the second 4000hex). If you have not figured it out already, in a 16K bin, simply subtract 4000hex, hence an address like 7A30 would become 3A30 and so on.

The locations here will be very useful in changing values in the ECU for tuning and modifications such as:
Larger fuel injectors
Modification of the AFM (voltage, air bypass, etc)
Installation of a different AFM
