Cannot lean out Uberdata idle

It actually turns out my WB was being shitty. One of my wires had been cut by my firewall (didn't put a rubber grommet or anything there to protect it). Working teriffic now, other than the vacuum leaks and broken BOV.

I am going to try lean out the entire map by ~20% increments.. if I see no change in the AFR then I know the problem is elsewhere.. I know it's not the wideband though because the exhaust has some serious black smoke.
Will post the results later tonight.. Anyone have a basemap they can send me that they have had some success with?

you are not listing to anything people are saying
find out what rpm your car is idling at. and the vacum where its idling and that where you make the adjustment.

What wideband are you using? I have a PLX M300 and it was reading rich. Turns out that my firewall had cut into one of the wires. I had to sodder it back together and shrink wrap it.
going to try to recalibrate the wideband and see if it yields different results.. but as I said before I can see black out the exhaust.

That would indicated a vacuum leak in my book.

finally making headway.. there is a vacuum nipple on the throttle body that was not connected to the MAP vacuum.. this in fact threw off everythign.. now the A/F looks good, however we are experiencing a self revving idle.. any ideas on this?
Thanks to all!

Surge in idle could either be a vacuum leak (my problem that I fixed this afternoon) or a dirty IACV.

Anyone have a pic of the IACV.. we seem to be missing some sort of sensor on the back of the intake manifold that is present on both the Z6 motor and D15B motor we have sitting around.. there is a plug and a two vacuum nipples on the back of the intake mani.. one goes to the FPR, but unsure where the other goes to..

White plug is the IAT - I guess new Ubardata scripts can use this..?. Only other things on the back is the IACV and the vac nipple for the EVAP solenoid from the charcoal can.

We have the White plugged in.. on the LS motor is on the intake mani kind of on top of the runners.. the other plug that is loose is a gray plug with 2 prongs.. circular. On the Z6 motor it hooks into a Black sensor with some sort of cap on the vacuum.. not sure exactly what this is, but the LS doesn't have this.
Unfortunately, there are like a dozen circular grey plugs. Could be for the IAT sensor, PCS valve, MAP sensor, TPS sensor, Coolant temp sensor, IACV, Charcoal canister, etc... Just from personal experience, every time I find a loose plug it's usually for the coolant temp (thermostat housing).
But the IACV doesn't have any vacuum nipples. It has coolant nipples. Coolant is supposed to circulate through it.
