I don't know how to start the recording with the datalogger yet. I will see if I can get the adx for you/
I think I got'em
they were both .php before I zipped them

I know these are not the direct values to put into tunerpro because tunerpro goes something like 14.0v, 14.2, 14.4 etc. I found a fancy calculator somewhere to convert the values for me. I think I have them written down here somewhere.
those are msec. a millisecond is 1000 microseconds (usec).
multiply by 1000. it may round to ~30usec
Making progress on the tune today. I used an interpolation calculator to find my injector offsets and the tune is much happier now. I still had to get the MAT compensation adjusted to get my AFR's inline but that was about it. the tune is very consistent and predictable now and I hope it stays this way. I think it just needs a street tune for the fuel map or it needs the power enrichment reduced. It's running 13.5-15 AFR cruising but 10 at WOT
Say you have a built engine like mine. You start with the factory tune and the only items that should need to be changed are Fuel/timing maps, injector offsets, cylinder volume, injector flow rate and initial spark advance. That should be it right?
Not as much progress as I wanted today. Some things I noticed that are going on. If I use closed loop it stays active or it's fuel trims stay active even after I turn it off again. What happens when I use the stock injector offsets with closed loop is that it can't properly control the AFR and it end up going really lean. So in order to turn off closed loop I have to set the closed loop enable as high as it goes and burn the chip then shut off the car and restart.
When I use the correct injector offsets they are not compatible with my current fuel maps because those maps were tuned around the wrong injector offsets. So what happens when I use the right injector offsets with these wrong fuel maps is that it runs really lean everywhere except for WOT then it runs super rich. My fuel maps are already skewed in a bad way for some reason so I don't want to tune it out like that.
Why is it that my fueling is so high on the lower KPA's? I know I must have made an adjustment to some kind of variable that did this but I do not remember what it was. It actually runs good this way but I know this is wrong and it wasn't always like this. I am posting todays .bin with the skewed map. notice it is really high on the left side lower KPA's.
Now I will post the .bin from xact dyno the day I dynoed almost a year ago. It ran perfect that day but if I use this bin today it is way too lean. What did I change that skewed my fuel maps so badly? I know my maps should look like this one from xact dyno.
You should be logging with a WB and a fuel pressure transducer.
I wonder what is happening with the BLM averages and O2 sensor data? See sample screen shots from TunerPro RT and Log File Analyzer. It would be very helpful to post a .xdl file for us.
