Factory rear O2 bungs?

Angled between 15 and 80 or 280 and 345 degrees?

AEM EUGO and again with Innovate LC-1.

Every winter the sensors failed within a few weeks of cold starting.

That's weird. Must be something specific to your exhaust. I am not aware of anybody running timers on their WB and they work year around... Mine is in 4th season one (zeitronix with run of the mill bosch sensor) without any issues.

I have an itch to hook up boost sensor to second o2 plug, the boost sensor would go on boost reference line from turbos to see what's happening there.

I plan on doing the same.  Get some real pressure loss figures for the intake tract, and know what stress is really being exerted on the turbos.  I've already got the sensor, just have to hook it up.

I would just steal Zeitronix sensor since it does nothing now that I log from the 4bar marvel in my TBB.

Same, I'm going to install my 4bar map any day now.

I'm trying to get my buddies innovate lc-1 logging correctly with me7 logger. I did the math, but something's not right:

0v = 7.35
5v= 22.39

22.39-7.35=15.04
15.04/5 = 3.08
0.004883*3.08 = 0.014688064

Factor for AFR: 0.014688064
Offset: -7.35

I hooked up zeitronix 50psi sensor to O2 input on ECU and now can log pressures inside the manifold as well (But will switch to N75 signal line to see what turbos are doing):

ZT_Boost_Volt            , {}                                , 0x381114,  2,  0x0000, {V}       , 0, 0,         0.004883,      0, {ZT_Boost_Volt}
ZT_Boost_PSI             , {}                                , 0x381114,  2,  0x0000, {PSI}     , 0, 0,         0.0610375,      20.75, {ZT_Boost_PSI}
ZT_Boost                 , {}                                , 0x381114,  2,  0x0000, {mbar}    , 0, 0,         4.20948275862069,      431.034, {ZT_Boost}



ZT_Boost_Volt - just pure volts input
ZT_Boost_PSI - vacuum/pressure in PSI. -14.5  --> 0 --> 35.5 PSI
ZT_Boost - vacuum/pressure in mbar. 0 --> 1000 --> 3448 mbar

Did anyone ever manage to log TPS with the Zeitronix on a B5?

I believe my zt-2 is seeing TPS.  Now I'll have to go back and check to make sure it's coming through accurately, but I believe it is.  b5 s4 by the way since you asked. I'm new to all this gadgetry, so take this with a grain of salt haha.  I'm going to try to do this mod next though.  I'll just need to figure out the stuff you guys are doing on the ME7 logger side.

So I hand the LC2 wired into the aux 1 which is setup as a narrowband emulator from the factory programming.  Fixed that, and my calculated settings work perfectly.
