Thanks
First the good:
Still not done, but it's already making healthy power, at least 10 more than my 01 did.
Ignore the bottom it's just reading the wrong output, not actually wideband/map sensor.
Now for the not so good:
We're running into a really weird wideband CAN connection/communication issue:
Every now and then, it loses all connection, freezes and just stops working. The TS gauge just freezes at whatever AFR it was showing before it does that, and the car then flips out, with EGO correction pulling fuel and all sorts of wacky stuff cause it thinks it's either rich or lean depending on what AFR it "froze" at.
Re-starting the car makes it work fine again.
@Reverant can you please help out with this?
Let me know what you need, a log, or whatever other troubleshooting. The AEM UEGO and CAN module came pre-wired, so I didn't touch any of the wires, and it works fine when it works. At first I thought maybe wiring issue, but re-starting car makes it work again, so I don't think that's it. Sometimes it actually un-freezes on it's own and works again without re-starting the car.

Here's a decent representation of what's happening in a log:
same run in all 3 rows, you can see when it's working and hitting 11.8 when triggering 12.3
then it freezes at 12.3 and stays there for the remainder of the pull
even when you let off and car is triggering 14.7, it's still stuck on 12.3 and won't move
during this time if EGO corr is on it will start pulling fuel and cause the car to run lean, obviously.
most of the time, turning the car off and starting back up fixes the problem and it works again.

Reverant sent me the instructions for CAN module and .ini file, so we'll give that a shot asap. Also thanks to bahurd for offering to send me his if Rev didn't respond.
Skunk2 throttle body is installed, and we tuned fuel/spark/vvt on this thing. Doesn't seem to gain any more power than the 129 it put down no matter how far you push either of the above 3, just shifts the curves around.
I guess that's completely normal though, can't expect an n/a BP on pump gas to actually gain power like the boosted cars
Car is real peppy now, feels solid, and OP drives FLAT OUT, all day urry day.

@Reverant
this is what happens when I try to download the CAN .ini file per your instructions
halp?
all the other settings in my TS are spot on with the instructions otherwise. but I still don't have the CAN .ini file
and the car still does this from time to time.
