As a result of throwing P1415 during the Auto VE tune, I've increased c6101 values by 40%. I'm logging DynAir in the scan tool to create a table of values to enter back into the C6101 table of the tune. Here are my current map properties:

Data tab-> Parameter (0) Commanded Air Fuel Ratio (:1)
Selected (checked)
Precision 2
Column tab->Column: (0) Engine RPM (RPM)
Selected (checked)
Col Labels: ,500,1000,1500,2000,2500,3000,3500,4000,4500,
5000,5500,6000,6500,6000,7000,7500,8000,8500
Row tab->Row:(0) Absolute Throttle Position (%)
Row labels:,0.0,6.3,12.5,18.8,25.0,31.3,37.5,43.8,
50.0,56.3,62.5,68.8,75.0,81.3,87.5,93.8,100.0

I came up with the row labels from the rows in the C6101 table. I'm not sure if Absolute Throttle position is same as "Throttle Opening %". Does this look correct for monitoring (mapping) values to plug back into the C6101 table? I applied this map to logged data in the scan tool and got the following average cell values (sorry I didnt just cut a paste a screenshot of this):

500 1000 1500 2000 2500
12.5 14.68 14.68 14.68
18.8 14.68 14.68 14.68 14.68
25.0 14.68 14.68 14.68 14.68
31.3 14.31 14.42 14.68
37.5 13.00 13.01 13.49
43.8 13.00

These values dont seem to match the values in the cells of the c6101 table. Do I have the wrong value set for the rows of the map?

The data units is mill grams per cylinder what it looks like you have there is commanded AFr if so that is wrong and you should prolly use one of the dynamic cylidner air pids located unter the "tune" dropdown you will have to conver gm/sec to mgm/sec

You may want to create a calc PID to convert the dyn air from g/s to mg/s

i.e. dynair/1000
