I’ll give it a look later. Did you end up getting the tuning school course?

I have it, but no time to look at it much. :smirk:

Trying to figure out this cylinder imbalance issue and make sure I'm not lean anywhere. .

I’m just not sure WTF is going on anymore.

Just can’t get this car to run right and be issue free.

Had DSX update the FPCM and no dice.

Still running lean.

Still has cylinder imbalance.

I doubt I’ll be able to get this car right before my license tags expire.

Fuuuuuu! :wall:

Get some help.  Another set of eyeballs, especially ones that know what to look for, PHYSICALLY looking your setup and tune over might be the ticket.  You have waited so long to be able to enjoy the thing and dont have the time to become a pro at this at the moment so let someone take a crack at it and then once its all solid, go back and learn to dial it in further!

PLEASE.  You deserve to have it at its fullest.  Make it happen.

Or sell the POS and buy a nasty ZL1!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Or a classic 1965 fastback with a stroker motor and T56!  You can easily diagnose any issue and be on the road again quickly.

Crazy, but a romp on the throttle got me 14.34 lbs boost at 7,088 rpm's. :stare: 

Odd it rev'd that high. :fear: 

I have it set to shift / rev to 6,800 rpm's max back when we tuned it together.

As far as I recall, it is mph based on the shifts.

Should my tune have "Cmd Gear Downshift Max Vehicle Speed" set to 93 for all gears like this?

My tune on the left, 2012 ZL1 stock tune on the right:

That's for tutd control. I'll have a tune for you by Saturday, 16 hour days are wearing me out.

The tuning school book claims the goal is to keep TCC slip down to 0-20 rpm.

Looking at my tune and I seem to have TCC Apply / Release Speed vs TPS vs Gear maxed out to stay unlocked for the most part at 318 / 317.

I seen one of my logs where it spiked over 1,300 rpm at maybe 52% throttle commanded.

What do you think?

Too much slip?

I know we need more slip at idle, though, because it pulls too much.

Also, TCC apply pressure ramp also looks nearly stock.

I'm told the TQ Converter clutch solenoid is in the TECHM.

If that is true, that is why the car shifts like ass (with the 6L80 and 6L90) and no tuning has corrected it. 

I think it's time to buy a whole new TECHM assembly.

Do you know the correct PN#?

I see they have different ones and looks like they go by build date.

I did see 2009 build decals on my car, but it is a 2010.

Anyway to know for sure by looking up the VIN# or something? 

ACDelco 24275872?

ACDelco 24275874?

Yes.

Tim King told me to just use the 6L80 TEHCM.

That's why the shift issue carried over to the 6L90.

I just wasn't sure if it was tune related or an issue in the TEHCM.

It's pretty obvious it's the TEHCM though.

So they have an early version and late...

I can see which by the build date, right?

Yes. Your should be a 2010 part, gm uses the model year for parts not build date.

Looks like it is the 2010 and later...

In touch with Tim King.

He said he might be able to swap me the 6L90 Valve Body / TEHCM by getting it flashed and then uploading my tune.

Figure it would work much better with the correct 6L90 stuff....
