Oh you,   most definitely not. 

I was hoping that someone from a former Nissan/DSM/Honda life had some exposure and experience tuning with them.

At the moment I know just enough to make me feel it would be fun to play with or beneficial for street tuning. 

Those guys dont tune cars.

Until then, the challenge of street tuning is like an addictive strategy game and i enjoy it.

Since it isn't feasible to dyno tune for all load points,just full throttle...

Um... I thought was the whole point of tuning on a dyno... or when you say "not feasible" do you just mean "not affordable"?

The dyno can put any load on the motor that you want, so you can set your throttle position wherever you want, adjust the load to put the engine at the desired RPM, then adjust timing and fuel to produce the most power. Adjust the load to put the engine at a different RPM, and repeat...

So, I have no valuable input, but they can be important and useful.

Since it isn't feasible to dyno tune for all load points,just full throttle, it is popular practice to base your part throttle timing on your dyno optimized WOT timing by blending it down through the part throttle range with a couple other rules of thumb involving when to pull/add timing relative to peak torque etc. It isn't incorrect to tune this way but there have been times where I have added considerable timing advance to part throttle, seen a significant increase in response, and questioned whether that was actually what the engine wanted or whether the EGTs were sky high and not advisable to run like that.
