Why so many errors? tunercats

So I got my tunercats today, and plugged it into my laptop and my Camaro to see what codes my car was throwing, as the SES light was on.
Not sure if this was the place to look but, under the Switch Table, I found many errors.

Error #'s
11
13
16
21
22
23
24
25
26
27
29
32
33
34
36
41
42
43
44
45
46
48
53
55
61
63
64
65
66
67
68
69
70
71
77
83
84
91
97

Also I noticed some of the settings discussed TCC (being a manual, should those settings be enabled?)
as Well as the Shift solenoid is that how one tunes out the Skip-Shift? (I read in the constant sticky adjusting the RPM's but I was just curious.

TC is not a datalogger. Those switches are what the PCM is told to track. You need something like DataMaster to log and see what your SES code is.

You are looking at everything that is in the PCM.... for both the A4 and the M6. I assume you are asking why the PCM is tracking DTC 83. That DTC is applicable to both the A4 (TCC PWM Solenoid Circuit Fault) and to the M6 (Reverse inhibit system). Ditto with DTC 84 - A4 = 3-2 Control Solenoid Circuit; M6 = Skip shift solenoid circuit.

Note that is is not tracking the DTC codes that are applicable ONLY to the A4 = 79, 81, 82, 85, 90. It is tracking DTC 91, which is for the skip-shift solenoid.

My remaining question was asking mostly about TCC control feedback.

and why would a manual transmission car be looking for feedback from a Torque Converter?

so your saying disable 84, and it stops skip-shift?

because I tried raising the RPM's to max, and it still forces the skip-shift.

To Disable the skipshift in the switch table of tunercat, it is call "c.a.r.s" just turn it off and no more skipshift.....Its that easy.

It is called CAGS, but for some reason its C.A.R.S in the switch table of tunercat.

I guess they were thinking(?) ... Computer Aided Ratio Selection. (You're not the only person who's been puzzled by this)
