Two different scan configs.

One is mostly trans only log while the other is scanning practically everything. 

Log_1.hpl

Trans Tuning Charts.Charts.xml

Channels_Config_1.Channels.xml

Layout_1.Layout.xml

Now for trans only via The Tuning School settings:

Trans_Log_1.hpl

Trans Tuning Charts.Charts.xml

Layout_1_Trans.Layout.Layout.xml

Channels_Config_2_Trans.Channels.Channels.xml

So what's up with this first log if there is no exhaust leak?

Only changes to the car were:

Catch Can routing and removed Mishimoto catch can

Exhaust back to catless

DSX Aux Fuel pump safety update and changed to kick on at 4psi boost instead 9psi boost because my FP was dropping out.

I'm telling you all, I had no AFR issues until I swapped on the cats and then back off... :confused:

Being super easy and smooth keep a more constant throttle produced this:

So what do you think is causing that and it trying to throw P219B code...?

Are filtering out any of the transient fueling? Which fuel cells are you logging? And how is your catch can routed? Does it pull Vacuum after the maf?

Transient, not sure.

Fuel cells, I suppose we can see that in channels?

Catch can has been rerouted. It used to come off the ProCharger filter on vacuum side and oil fill cap with -12an via catch can.

Now it pulls vacuum for the catch can behind the TB on the intake. The vacuum port just before it is capped off.

The line that was on the ProCharger filter is routed to the drivers side valve cover pcv now.

Transient would be filtering throttle opening movements like greater than a +\-5% movement in a 5ms period and your fuel cells would be just a filter on your graph. And I’m assuming your also filtering for eq =1 right? Your line off the fill cap, is it capped off or hooked to a vacuum, open air, or ?

Can is not open air until it sees pressure from blow by.

I got the Camaro 5 Wild with -12an line off the oil fill cap.

All pcv lines are capped except the ones pulling vacuum on the intake behind the TB and driverss side valve cover.

L99 stock had a line off passengers side valve cover to intake pre TB and one off the valley cover to behind TB.

Guess I need to re-set up my scanner to log this stuff with all that junk filtered out.

If you can, post a list of all the filters. :up: 

I need to fix this stuff before I tune the trans, right?

I need to re-setup my logs....

But I will say this.

The car, at times on the 2nd to 3rd shift feels like it tries to shift too fast and clunks in to gear like it didn't release the last get quick enough before engaging the next.

Weird part is that it doesn't do this every time.

More often than not, it does it after a cold start right after pulling out of a parking space or my driveway.

Post your current tune and I’ll take a look if you’d like me to.

If you don’t find any tune issues, then I’ll try a relearn.

If that doesn’t work, I’ll bet the TCM has issues.

The TCM is part of the valve body inside the transmission.  Have you pulled the tune out of it and edited it or did you just flash the 6l80 tune into it?  

You probably need to pull the 6.90 tune out and edit it with your shift timing, pressure etc tables and do a "write entire".
