I looked up a 2011 5.7 Ram tune and saw that table 12882 was completely different.
2011 values are a lot smaller but is based on Torque as opposed to MAP.

Could this be my problem ?

...

It stopped snowing again and was able to test the updated tune. At startup idle immediately returns to 650 rpm. Turning on A/C - idle becomes 800 rpm.
This is all good !!

TaylorJ thanks for all the info - I didn't see your response when I posted just 2 hours ago.

Yes - this is a used PCM that purchased with what I thought was a factory 56030033AI Flash. (...

Thanks for reply!! - I looked up table Torque Model/Loss/Base table 12882. Don't actually understand it or why it exists. In my setup there is very little load on engine, A/C, alternator,...

Well the weather is finally good enough to do a real test drive. Car was just up on blocks before.

Regarding the Torque Management issue, I am testing fooling the APPS with a couple of...

Thank you again for your comments and research !! Currently trying another route as well. Fool accel pedal voltages during shift , so PCM thinks driver has taken foot of the gas. To...

LilSick - even worse A606 transmission.

Thanks again everyone - so question becomes - with the low - -20c IAT - cause a change quick enough , or will PCM ignore this change and/or use an averaging approach.

Everyone ! Thank you for your comments and suggestions. As I stated, I am completely new to tuning.

By fooling IAT to go low, wouldn't extra fuel be pumped in so going lean would...

LilSick - Thank you for the reply !! I didn't mean any dis-respect to anyone !!

OK - I did go find my 05 tune. What you describe is 100 % correct. ( I can load it into the PCM as well )...

Thank you PurpleRam. I understand your comments. I have also seen that "available tables" change according to Flash let alone model year and NGC version.

Thank you for helping !!!

I can't find:
engine > spark > advance > IAT > ref part throttle > 30 C
engine > spark > advance > IAT > cold spark ref > 0 C

Attached is the tune.

Here is my file so you can compare . Maybe it helps !!

That sounds like something to do with "Key/Power ON Time"

So I have continued my quest to "remove timing" at will. I have "window switch" so that I can cause IAT to read -4 C at will.

Looking for any table that is based on IAT,

I have same setup. Fixed problem this way - see https://forum.hptuners.com/showthread.php?102194-2008-Ram-5-7-high-idle-time&p=718428#post718428

For what it's worth. 2005 Ram 5.7 - I set rpm to idle ( 624 or 800 ) in all of these tables (GREEN) . Engine starts and immediately drops back to 624. Also changes "high idle" ...

I just discovered the same thing ! I also need some guidance to get started with tuning 2005 hemi.

Thanks for you comments. When I look at Thermal WOT table, I see only MAP - kpa . I don't understand how I use this as IAT temp ?

FYI - I monitor TCM and it can output a "window...

I have a 6.1L running on a 2005 5.7 controller. Engine runs fine but I'm sure the tune needs a review !!

Problem is - its connected to a 42LE transmission and so I've lost all...
