Use the maf ad counts givwn in the histogram which gives the maf the most resolution. Then just leave the histogram up drive and apply the correction tunerpro gives you.

/done

you dont have to calculate anything it tells you the error

I believe I understand what you were saying now bout how I won't be able to tune the MAF table the way I had it configured. The AD counts in the table aren't "friendly numbers/increments" and also don't translate well to the logs. If the log values for AD counts in the histogram are based on say 200, 225, 250, 275,etc. but the MAF transfer AD count table is say 212, 241, 268, etc. then it's not easy to tune since things don't evenly line up.

Changing the MAF transfer table's AD counts to increment equally as the histogram log table so both are 200, 225, 250, 275 etc. means the reporting AD count range is equal to the config range. Almost like having table X in Fahrenheit and table Y in Celsius. Just stick with one or the other so no guess work ;)

Here is the old which was copied from the 80mm Lightning MAF transfer table (original table in Volts, this table was the resulting conversion in TunerPro for AD Counts) vs. the new AD Counts column I somewhat mimiced from the log history table. I tried to give myself the most resolution in the AD count region I've seen the most which is 200 to 700+ish.

you only need to go up to 1024 you dont need 3200 in GUFX since the code wont allow it

might as well ads 850 ad counts

I tried 9999 and it converted it to 3200. I figure this compensates for a critical failure like setting 16+V because I have seen batteries over charge to 16.8v before due to a bad regulator/rectifier.
If you are confident on that hard limit at the code level, then I'll gladly add 1 extra point of resolution.

I know you read these and your time is valuable so I'll go with no reply means,
Yes, do it ;)

After a couple decades of log/trend/performance analysis in the IT Security space, yep, no F'in way was I gettin this tune done right without having the simple/logical MAF transfer table column to adjust based on the log history :D

Dialing this in just got a hell of a lot easier. Before I can see it would've been a never ending fight. Now I'm riding very close to 1.00 in all AD count ranges I've hit. Good call!

I extended your definition file for the N_IMAF_IEGOs (I know I can use IEGO1 since I only have 1 O2 sensor but meh) to 15 columns up to 4500 RPMs which gave some more helpful data for me. I'm on 35" tires and 5.13 gears so over 3K RPM is not unusual which was where the cut off in the definitions is. 2K is like my average cruising RPM with the tires/gearing. Not complaining either, just sharing ;)

I've gotten a lot of progress especially with changing the History Table Rows to match the AD Counts I have in the MAF Transfer table. My MAF transfer based on AD Counts is below. I spaced the rows values by 25 for the areas that had the most activity, with broader strokes elsewhere within the 30 row limit with 0 and 1024 required for max/min, then matched the History Tables so I have a 1:1 comparison from log to config as suggested.

I've got things dialed in nicely now and I've had some questions about what I observe in the "Fuel_Err_1+2_Filtered" (Z object) with AD Counts as Rows Y and RPMs as Columns X (based off N_IMAF_IEGOs). I'm attaching my XDL Log file (flat street to uphill to downhill run) and Definition File as well. My History Table is "Bonnie - MAF AD TuningZ".

The AD Count values in the same row decrease as the RPMs increase. Examples (not from log file attached. These are from just a pure flat street run):
AD Count 900RPM 1200RPM 1500RPM 1800RPM 2100RPM
300 1.075 1.021 1.003 0.923 0.919 Average Of All Rows: 0.9882
325 1.069 1.045 0.980 0.927 0.925 Average Of All Rows: 0.9892

If I take the average values across the rows, then I'm pretty much spot on, just a tad rich. But that's per RPM range. So example for 300 AD Counts... If I spent 98% of my time in the 2100RPM range, I'm running .919 average (fairly rich) then the other 2% of the time in the other RPM ranges, say 1500RPMs, then I'm at 1.003 2% of the time (damn near spot on).

I've found the Parameters, "Y - Adapt Load Scaling - FN021" & "SP**FN1036B - DECIPHA Inferred Load (FN1358)"
These seem to have some relation to the differences across the single rows relative to RPMs which to some effect is relative to Load.
The scaling values for those Parameters seem to kind of correlate to the "downslope"? of AD count values across the RPMs that I observe.
Is that true? Regardless, can you explain these fields and maybe how you'd consider tuning them or at least consider them in your tuning calculations? And if I'm wrong, please point me to a better Parameter/Function? :)

Thank You!

I replaced my MAF sensor and the stats were more consistent so I'll mess with this some more.

My main question is what are the parameters "Y - Adapt Load Scaling - FN021" & "SP**FN1036B - DECIPHA Inferred Load (FN1358)" used for and how do they factor in the calculations the ECM does? Also what does the blue/red color mean in Inferred Load?
