I am no expert on Honda and the "lean burn" mode. But I think for best cruise MPG you would want to try something like that.
Under the right conditions you lean out as far as possible (will need testing) if any of the conditions change go back to "normal" mixture ratio. I think you might have to play with mixture and timing here.
Example you step on the Gas to accelerate. The engine load goes up (going up hill). I think you get the idea.
Now how many times can you change the mixture and timing?
Have one for gas pedal to the floor (max power & max load)
Have one for normal acceleration (medium load)
I think you get the idea.
I think you will find 1 AF ratio and 1 Timing is not going to cut it.
That said sounds like you have a lot of fun experimenting ahead of you.
