Confused on coorelation between Integrator counts and Inj DC% and/or Base Pulse width

[sabino56]

Hi,

I have 93 C1500 using 16168625 with standard code BDJZ. I haven't modified anything. I am using TunerPro RT and using A201_E6_v250.adx & E6_TPV5_v250.xdf

I'm trying to learn more about the system, how code controls injectors - rich/lean with feedback from O2 sensor. I've collected data from a hot drive and can see the O2 sensor varying. I see that the code does a good job - Rich/Lean flag correlates well with the O2 sensor. [ATTACH]13587[/ATTACH]

I can see that Integrator counts correlates well with Rich Lean flag and BLM adjusting with driving conditions, BLM cell changing.[ATTACH]13588[/ATTACH]

I can see that Int counts correlates well with O2 sensor when BLM is constant. I assume Injector counts is like "fine adjustment" and BLM is like "coarse adjustment" - I need to read up/understand that better. [ATTACH]13589[/ATTACH]

I expected to see that Int count would correlate with Inj DC% and/or Injector Base Pulse Width - but I can't see correlation with either. [ATTACH]13590[/ATTACH][ATTACH]13591[/ATTACH]

The closed loop is obviously working - I just can't see how fuel flow is being modified in the data stream. What am I missing?
