Best Pin to use with my setup? + uego

[projekt1]

I've been doing a lot of searching but I can't get the answer I need for my setup. I have looked at many others but still have the question.
I have 30-4100 gage type UEGO and DSMlink with the GM Maf cable for the 3" GM Maf (not Maf Translator box).

Ok so here's what I've gathered:
Pin#8 is for IAT, which I'm using for my MAP sensor (wired into the IAT input on the GM maf cable) --btw, is this correct?
Pin# 15 is for the EGR but if we tap into that it won't go under 11 afr.
Pin# 16 is for Baro, I think this is where I should wire the UEGO into

After I find out which pin, should I cut it or splice into it?

How do you guys have yours setup?

Thanks...

I have it in pin 15, it reads below 11:1 AFR, but it seems terribly inaccurate or delayed.

Would that be the egr(cali) pin? Blue with yellow ttracer? Can you please explain how it is inaccurate and delayed? Is that on mmcd? I am going to do this, But if it is bad then i dont want to waste my time.

If you have our GM MAF cable and you already have your MAP wired into the IAT input (which is unusual, but perfectly fine), then I would suggest wiring the WB into the baro breakout on the GM MAF cable because it provides a buffered input to the ECU.

GM MAF cable details

The AEM kits are well known for producing mappings that don't seem to match their documentation and being unable to drive certain ECU inputs (EGR temp being one). So using a buffered input is the best way to get any reasonable value from the AEM WB. And even then you may find that you have to work around the mapping a bit. This page has information on how you might go about that.

OK looking at this from a logical standpoint. IAT is not MAP. MAP is Baro (manifold air pressure = Barometric pressure)
AFR is "air fuel ratio" or the UEGO off the narrow band tap on the gauge.
EGR "Exhaust Gas Recurlation" I am lacking the detail on how that would work with the DSM link.

Any of those inputs can be remapped to be whatever he wants in ECMLink.

If the pressure sensor is working OK on the IAT input, just leave it. It's better to use the buffered baro input for the WB given AEM's issues.
