Do we trust mazda to use terminals that match the capacity of the wire?
What about using both terminals for power and grounding to the actual fuel pump assembly inside the tank?

Well, you weld the NPT bung on the panel there, then the plastic NPT pipe plug is an insulator.
If it were me, I'd drill and tap the center of the pipe plug for a 6-32 brass machine screw, then use ring terminals soldered onto my fuel pump wires. I'd attach the ring terminals on the brass allthread or cut off bolt...
Kinda like the through panel terminal things you buy, but with NPT seal and all diy.

Oh and today I played around with timing maps. And mine is pretty much identical to DIYAutotunes 1.6 base map. So I'm comfortable running that for now. Called around and found a load bearing dyno, so I will be going there after I re-gap the plugs, install the fuel pump, regulator, and flex fuel sensor, and continue reading about tuning timing. This has been the most help so far.

Does fuel need to be adjusted with timing? Or will it be 11.5AFR at 10* BTDC and 20* BTDC?
I want to tune pump, then e85. Then test the flex capabilities, and then dyno tune for spark.
I think my goal is going to be a nice 180hp tune for track season next year. I'm going to be on better tires, brakes, and I like to think I have improved as a driver a little bit.

EDIT: Deleted some of that, didn't make sense. Hmm...

My approach is to tune fuel ahead of the time on the street with the wideband, then do the timing on the dyno. I keep an eye on the fuel, but I don't mess with it unless it starts going outside of a range I'm comfortable with, or it pings and I want to see if I can fix it with a bit more fuel. Once you've found MBT you can go retune the fuel on the street afterwards if you want to.
One of the reasons why I've never messed with water/methanol injection is that supposedly it and the fuel affect each other, so it takes a bunch of back-and-forth tuning to get it right.
BTW, a load-holding dyno offers what appears to be an appealing on-the-surface idea of tuning individual cells by telling the dyno to hold (say) 5500 RPM and setting the boost controller to the desired MAP value, then fiddling the advance up and down until you maximize the power. I say on the surface because this is very heat-intensive on the motor, and (I'm told) it will ping with much less timing than it would even when running in that cell on the track.
