LS1 ADX V1.6 to suit Tunercat OBD2 Cable, AVT 852

Forgot to add in above post that at atmosphere SAE gauge is displaying 95 KPA vs GM MAP KPA 106

After some more playing with formulas and calculating what x =
I've tested the following formula for 2 bar (x + 14 ) / 1.33168
I'm not sure how the + 28 was determined for 1 bar setup but guess there must be some science behind it, I therefor halved it for 2 bar setup.
When I know compare GM enhanced values to SAE MAP values i get the following :
MAP sensor input disconnected SAE 10 kpa compared to 10.513 on GM enhanced
MAP sensor vented to atmosphere SAE 95 KP compared to 96.8 on GM enhanced
Full pressure applied to MAP sensor (4.996v) on input 202 kpa on GM enhanced and SAE scale appears locked at max 105 KPA which i'm guessing is looked at this value by the ECU as generic OBD scantools has the same result.
I've compared values to scanmaster ELM and had 10 kpa sensor disconnected and 95 KPA when vented to atmosphere and max's out at 105kpa as above suspicion.
Appears to be close enough ?

Yeah at that point it can be explained by the resolution in the data, or the resolution in the A/D in the PCM.

So I've been having a bit of difficulty with gettting this ADX to work with my AVT-852...

What should the configuration/plugins be for the datalogging settings in TunerPro? I've tried several different
combinations of parameters and the best I can get is a connection but no PIDs as it just shows as
data errors on the status bar? (This was with the TunerPro I/O default plugin set to the COM port for the
AVT cable)

I have confirmed the cable and port combo function properly with TunerCAT...
The machine in question is Windows 10 based.

Thanks in advance!
