Problem pasting my maf #'s

[med]

I am new to this so its probably me. When I paste special % by half I am getting numbers that don't make any sense.
This is what I get when I paste special% by half:

0.18808 0.29246 0.42370 8.11646 11.41306 15.92185 22.55846 30.83819 40.98531 54.23785 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 67.72497 25.72691 28.33009 30.85783 33.85474 37.13583 39.77621

From this:
2,476.0 2,749.0 2,967.0 3,243.0 3,616.0 3,895.0 4,229.0 4,498.0 4,773.0 5,108.0 5,350.0 5,688.0 6,019.0 6,243.0 6,588.0 6,865.0 7,188.0 7,526.0 7,807.0 8,045.0 8,452.0 8,696.0 8,969.0 9,250.0
The numbers don't make sense to me.
Can anybody tell me what I am screwing up?
Thanks,

what kind of car/year/model?

[med]

06 Chevy Colorado 3.5. When I copy my data from my log. and paste into the tune for the maf. I see those numbers change. I tried to get a screen shot and I failed.

[stromboli86]

are you logging MAF hz and pasting those by half to the values in the MAF table? I would imagine you need to do the same as what I do with my cobalt. You need to make a histogram that has the same labels on top as the MAF calibration table and then log/plot fuel trims into the values below. I.e My histogram is called LTFT+SHFT vs MAF Frequency. Then you select the cells in the histogram of the log that display the fuel trims and how far off they are and paste them by special to the values in your tune.

heres a link for the cobalt but same idea: http://www.hptuners.com/forum/showth...af+calibration

Yes I made a histogram with maf hz. Logged those values with the scanner and displayed the histogram. Copied those values and pasted special to the maf tune. Then I get those huge numbers.
Thanks

can you post the log and config files you were using?

What exactly did you log for the MAF? You need some fuelling error data (Wideband AFR based or by fueltrim logging) to correct the MAF slope...

I will post what I have Tuesday. I appreciate your help.

I have not had any time to work on this. I did get my Dynojet wideband installed. The gauge reads 14.7 and when I hook it up to the scanner I'm getting 17.8. I used the config that came with the software. Its logging, just not the correct volts?

Probably the offset for the wbo2.

[med]

I have adusted the offset. Thing is how do I know what the actual #'s are?
I made it to match the gauge. Hopefully thats 100%.
I did get my logs figured out. I was missing the sensor in the histogram. I have it measuring lambda = 1. A lot better to adjust the tables.
Thanks for the help.
