Good work but i don't see how richening it up under power throughout the whole rev range has enabled you to get better economy while cruising.

There doesn't seem to be any change in the AFR's. You could richen it up almost the same just using the overall adjustment on the ECUTalk.

Does the module allow you to adjust the fuel under different loads as well as rpm?

There is always nistune which allows you to alter the ignition timing as well.
