Doing a tune on a 2017 l83 and looking at the cam position tables (b7934, b7935, b7936) and the x axis does not look anything that I am use to... Not sure if I am missing something.
If it is correct, how do you log vvt with the scan tool? I am logging e92.apcyl_dma, rpm and gm.incamab1 and nothing aligns in the table from the scan. Thank you for any help.

Have you tried logging GM.INPHAB1 to see if Actual angle appears? I'm not sure about the PID you posted.

What ECM OS is that in?

The one that I am logging is Intake Cam Actual Phase angle.


What ECM OS is that in?

The OS is 12677878

Not sure if it is related, I tried to log GM.INPHAB1 but as soon as I tried to record OR monitor, no data would update. It looked like all the data was static and like i was not monitoring/recording at all. Once I removed that pid, everything went back to normal.

GMPX - were you able to find anything?

Also try GM.EXHCAM1DC.

Also try GM.EXHCAM1DC.

What is the benefit of this pid? If I understand correctly, this is the duty cycle for the exhaust cam. In a crude way, will this not just tell me how much oil is being diverted to the phaser?

I guess in another way, can anyone share what pid's they are logging when they tune vvt on an e92 ecm? Also, has only else seen what I shared in the screenshot?

It looks as if the first 5 Column labels are completely wrong.

TTT.
Is there anything that I can do to correct the lables or is it in the calibration file?

You should be able to right click and Edit Row or Column Labels.

By doing this, does it affect the tune at all?
I can see that when making this change, it only takes effect on the tune that I made the change on, nothing prior and no other tunes with that OS.

I will bow to the experts on that one, there's probably something else in the software that affects that.

Bring this back up. Still an issue and curious if it will be corrected.

Sorry this just kept slipping under the radar, you can't fix the labels, it has been incorrectly defined in the .calz file.
Noted and will fix.

FWIW, it is just a display issue, the actual table values (as in the values in the 3D map) aren't skewed by what is shown in the axis value, the axis values are just coming from the wrong place (to fix them would be a disaster, the .calz needs to be fixed).
