wiring in pressure sensor for logging purpose

[TimTaylor]

As my boost is dropping at higher revs and I cannot clearly figure out why, I want to install an additional pressure sensor that tells me the correct pressure rates.
So I can see the pressure:
A) before the intercooler core
B) backpressure of the exhaust emissions in the exhaust
C) backpressure of the exhaust emissions in the exhaust manifold
D) somewhere else you might suggest helping spotting the cause of the problem

This should be for logging purpose only. It should not affect any of the values used by the Syvecs to control my engine.
I have the Toyota MR2 §S-GTE engine, so the question is, where shall I connect this sensor to the ECU?

I have spotted the following inputs and only one that appear reasonable to me (maybe because I don't clearly understand what it is good for ):
Barometric Pressure Sensor

Inlet Port Pressure 1/2, Manifold Absolute Pressure 1B, 2A, 2B, Fuel Pressure 2-4 and Engine Oil Pressure 2-4 are available as well, but I am afraid, they might somehow interfere? E.G. if my oil pressure 2 is reading at -0,7bar on idle because I put the additional sensor in front of the chargecooler and My S6 thinks "What's going on, negative oil pressure... quick... stop the engine to prevent any harm".

AN03, AN04, AN11,AN12 are free to assign... can you suggest me, which I should choose?

I am going to use a 0-5V 10bar Sensor

From reading other posts, using existing features like MAP or Oil pressure could see you hit failsafes or limp modes.
Not sure if using more than one MAP input, whether it affects the actual MAP value used for the fuel etc

So for the purposes of testing if you wanted to use those items, you'd probably have to turn any safeties off.

It would be nice to have some simple generic un-named or user named inputs for doing what you describe

Any of the analogue inputs should be fine for a 3 wire 0-5v sensor.

I think some have set the input feature to some obscure one that will not affect any tuning, then for logging just log the raw ANxx value as a voltage and work from that instead, rather than logging a pre-defined named parameter.
