Is there a PID to log injector advance? I'm trying to calculate SOI and EOI to compare against commanded camshaft advance angle and to monitor EOI vs spark advance difference while adjusting my spark advance.

Thanks in advance

I probably should have mentioned it's an e92 controller on a 2014 Sierra, 5.3L

I don't think so sorry, it is probably not something GM considered necessary for Diagnostics.

Hmm.. That's annoying.

Can you tell me if this will work like I expect it to?
I figured out how to update the e92_links.ini file and changed all the links using E92_APCYLAIR_DMA to use CALC.CYLAIR, so I can at least see the runway highlighting in the tune file, which will get me close to the right cell when I highlight a section of the log file.

Then I have a map where I am calculating CAdeg the injectors are open. I can at least get close that way. I know there are some adjustments the ecm makes to the actual SOI event from the MULT tables that I can see in the tune.
