smooth it, you can use i think both efi live and hptuners to smooth and leave max cells or smooth in general. i most of the time use both, as just smoothing sometimes lowers it too much

Smooth it manually, else you'll change your known (good) values.

I agree. Hand smoothing only.

I personally don't, but then again, my car is slow, and everyone thinks I'm an idiot.

How do you hand smooth? I tried the click & drag method on the 3D chart. Is this best method?

You can click and drag, or you can just highlight whatever cell you are interested in, and then you can increment it by hitting the + or - buttons on the keyboard...it'll increment by whatever your accuracy is (like .1 if you table reads to the .1 decimal place).

I generally use the auto smoothing button when first roughing in the tune, then do it by hand when the ve table is getting close to correct. The closer everything is, the more it needs to be done by hand.

Yep, same here. Initial VE will be very approx due to not all cells being filled so hammer the whole thing into a nice shape. Futher iterations will require less violence until at the end only regional petting will be required.
