I posted this thread in the tuning section, but it may be more appropriate here, as I just need to find the locations of a couple of variables in my ECU.

Anywho, on my car I've currently got one OEM EGT installed, and Zeitronix EGT sensor.  Each of the EGT's serve a purpose as follows:
Zeitronix--
-I can log real time values, below the threshold of where the stock ones don't read.
-I can use an EGT threshold as a trigger input to my Zeitronix ZAVT-1 alarm box, to potentially trigger other relays in case of hardware failure
-They're reliable

Stock--
-Can utilize the stock safe guards relating to the EGT triggers in the ME7
-1 is less likely to fail than 2
-I kept an old one that is still working, and sold a new one (the newer EGT's from Audi have had a much higher failure rate)

Of course, a single EGT can only be installed in one bank, but I figure a single bank is better protection than no bank, and any global issue won't be bank specific.

Currently, I've got the EGT's tuned out, because I've only got one hooked up.  My thoughts are that I want to figure out how to have the ECU read the input from one sensor into the calculations for both EGT sensors.  I've done a good amount of reading and I'm pretty sure I've figured it out (if some random flags/checks don't stop it).

Right now I've just got to figure out the location of these variables in an M-box for a 2.7t S4:

tcchats_w
tcchats2_w
tccpats_w
tccpats2_w
p_ats
p_ats2

This is the hard part for me as I have no idea how to go about disassembly.  Can anyone help me find the location of these variables, or possibly point me to somewhere where I can figure out how to find them myself?  Much appreciated!
