My formula ended up being:
0.03913*x+8.7
I think geographical location will determine what your formula will be. Altitude, temperature, air density and humidity will to some extend affect
Now I just need to figure out which CEL I triggered.

After running this for a few days with all fine, i applied the 02 sim patch and during my next logging session in EvoScan my AFR values were like 5-6 points low. Idling around 9.5-10 the only change was 02 sim patch. I removed patch and readings in EvoScan were back to being calibrated to gauge with original formula. Any ideas? Do rest of you leave un-patched until inspection?

I use inline crimpy thingies....but I still don't like wiring the wideband of AEM's into the ECU. For some reason, I see too much talk about it being inaccurate. One thing that is neat, is the OpenPort 2.0 supports serial in, so you can wire the serial out on the aem wideband to a serial plug, that you can use on your computer, or you can use the standalone logging, and plug the serial into a converter to a headphone jack, plug that into the openport 2, and setup logging there.....self contained, accurate as hell, and pretty dang easy, if you have an OP2.0
My one issue with that, is that the logs don't open nicely in EvoScan.

Ive some question as ive an Evo 6 ecu and on the 6 wire diagram the pin 75 is stated N/C.
My question is :
1) Do i still connect my Uego WB white wire analog output onto pin 75?
2) Hope you do kind to share some steps on how to do it in your way...

I have problems too, my AEM UEGO shows always 9.0 on evoscan. 
The wire was checked with a tester and in idle the wire shows 2.8-3.2 volt the signal is normal I think. Is something wrong with the formula or the address I don't know, need help here.

Can someone explain how this formula is calculated? I would like to know which numbers affect what. Thanks!
Also! How do I find the "rear O2 patch" on Ecuflash? I do not see it listed.

Which in turn has the formula with V being volts.
0.039137255*V+10
However since X is NOT volts we'll just have to figure that out...
As noted in the graph max voltage is 5 volts which will end up being 255 in terms of X in evoscan.
Volts = X / 255;
Minimum AFR is rated to 10 in this graph and max of 19.98. So we could say that 5 volts is equivalent to 9.98 + 10 (base AFR).
Baring that in mind you'll end up with something like this
((X / 255) * 9.98) + ( 10 minimumAFR) = AFR;
We could shorten this up a lot by creating a factor for X which would be 1 unit of x
factor = (1/255) * 9.98
This ends up being 0.039137254901960784313725490196078
But to shorten that up it ends up being 0.03913*x + baseAFR. Hope that clears it up you guys can figure out the equation based on your own thoughts now.

Instead of cutting the ECU wiring could a T-tap connector be used instead?
If you need a visual indication:

That way, if later down the road you realize this modification just isn't for you all you have to simply do is remove the connector. Splicing the wires back together wouldn't be an issue.
