On the transmission side: watch a couple of youtube videos.. Don't overcomplicate it !!
The 6l80e is awesome once you get in dialed in. In general: Remove TCC lockup totally in 1-3 gears.....

My 2014 Yukon Denali uses pattern A as normal/regular. And Pattern B is the tow/haul mode
HTH

I'm glad someone chimed in with real world use.. I haven't been able to test my override fan settings... yet...
Gotta get warmer with the camper on. But glad to know that it does help. Thanks !!!

That switch came with my cooler. I didn't use it... As I want control over it (ocd)
When i know a large hill or something is coming up I can flip it on before all the heat so I'm not
trying to...

Unfortunately this is how the SUV's air flow system is... There's no way to get 24x24 Air Into the Radiator
past the bumper/cover/ etc . Then past the oil cooler, the ps cooler, trans cooler and to...

YUP, that's what I ended up doing as my 14 yukon denali had NO settings for MPH/Speed in correlation to fans
I went into the "override parameters" to set my fans to come on at about 218 ish.
I...

On my Yukon, pattern B is the "tow/haul" mode... I compared the shifting tables to the pattern A and made my regular mode more
like the tow mode. Hated it shifting too early and then in and...

Its about the same.. Just more gears and lockup "can" happen in all gears
Turn off lockup in gears 1-3. I also tow with my Yukon heavy. It's 2014 so diff engine, but same trans
Also reduce the...

They left the lockup function on in 3rd - 6th gear....
So gears 1-2 just ignore, it'll never lock up
I'd get rid of lockup altogether in 3rd gear - it's kinda silly to have it in...

WOW .. Just a quick look at your timing tables and idle timing.... way too much advance like Greg said..
I'm no expert like he is, but that's a lot of degrees !!!

Post your tune so people can look at your parameters and give your help !!!

More info needed on the year, make, ecm, etc etc To be able to help

Pan temp almost always reads lower than the internal temps read by the ecu...
Only time they really match up is sitting in traffic or a drive thru for an extended time..
So that's a good thing.....

In my older 4L80E the pan temp and the internal temp do not match exactly most of the time... Only at cold start up.
The electronic sensor is in the valvebody somewhere and my gauge temp sensor is...

The pushrod length should always be dialed in anytime you change components.. But yes, the 7.4 is the normal so you should be ok.
And the springs are good too.. Just didn't mention those in post...

You didn't state if which pushrods and valvesprings you used when you installed the cam...
That would be useful . Hope you didn't use stock stuff.. also your rocker arms should have been...

Serious Mechanical Issues for sure

I bet you are looking at the auto trans values.. I've not seen those in manual selection.
But it's certainly in the auto side of the values...
but either way, it wouldn't hurt anything

I have a 4l80e that is built to hilt in my stepside.. Controlled by compushift standalone
During raceweek a few years ago, it mysteriously decided to not upshift from 1 -2 at WOT...
Lost in...

Crap.. I'm wrong.. I looked up P0100... fat finger I guess.
IF it's a larger cam, then the VVT tables will need to be modified.. And possibly a cam phaser limiter should have been installed too

That's a mass airflow code... I'd check for mechanical things like a vacumm leak, wiring, loose air intake clamp etc in the air intake system..
And then clean the MAF, etc
Likely an old...

If you already own a diablosport and plan on keeping your Yukon stock... Just buy another VIN license for it
so you can tune out the DOD...
Unless you want to improve your transmission...

Might check/reduce your minimum airflow while in gear section... It could be holding the Throttle open a bit too much

Following this post.. I've done the 6L80E's but really not much with the 8 speed. My son wants me to tune his 2016 Yukon Denali, so
I'd be interested too !

you could temporarily change your AC fan settings to see if that will keep them OFF.... IDK if your ac system works or you are going to make it work...
But listen to GHuggins on this for sure
