My First Scan w/ tune, what do you think? Some weird KR showed up. Unfortunately, not sure if this scan was using the WB LC1 correctly or not. I see WB being listed on the PID, but I tried adding one of the pre-configured PIDs in HPT for LC1 WB Logger, but nothing showed up in the logging. So hopefully I did not waste 30 mins of driving and gas.
Anyways, the files are attached. For some reason got some KR while driving, was weird to see, b/c its not even associated with hitting the gas hard or tapping out the rpm's.
I also notice the injectors are hitting 17.8ms at the highest, not sure what this means...
Other than this, how does it look, and what should I start to dig into and fix?
Edit: Shoot! I cannot upload, file too large. How can I get this up???

Log files are not attached.
You want to check the wiring hookup, last I looked
each of the preconfigured PIDs expected the input
on a particular EIO pin and they weren't always the
same one. Dig into the documentation for that. And
of course you'd like some idea that the LC-1 itself
was behaving right, know the output transfer curve,
see it bouncing at idle about an indicated 14.7:1 and
so on before you go trusting it for tuning.
Take the injector pulse width and turn it into duty
cycle (forget the formula but it's been posted) in
Excel or as a custom PID; the main value in it is to
see how close you are to running out of fuel delivery
(at which point you can't tune squat up top and
more airflow from mods helps none).

any help on posting the file is appreciated. I cannot get it up.
And I remember now, when looking at the PID live data, I was able to compare the AFR Commanded HiRes vs the WB LC1 EIO Input 1.
But when the data is exported, it does not show these two things on the excel chart....
