Cobb MAF Calibration help

[Denny McLain]

Even though my car is in the paint shop, trying to do a little homework to calibrate the MAF settings. Does anyone have a stock intake MAF log of 2500-3000 rpm and up they can share with me? Also, those with the Cobb AccessPort......are you able to connect your laptop directly to the ECU to do logs? For some reason in trying to get the two to communicate, keep getting communication errors preventing me from logging short and long term fuel trims. Might have to call Cobb for help if I'm a Lone Ranger as Calvin at Cobb did use his laptop for logs.

Anything upstream of the MAF (Like a Stillen Gen 3 intake) can skew the reading plus there is a probability of MAF production error so I'm trying to figure out exactly what is going on. One side shows more voltage at the same rpm (as much as .06 volts in numerous points) than the other side through 85% of the power band. Suspect it's the Gen 3 intake vs MAF variance.

Also the logged Grams per Second using the AccessPort is much higher than the stock MAF table but leery because the log table stops at 268 grams per second (5900 rpm). Btw... it is both sides added together. How do you fine tune if it stops giving ya data above 5900?? Does the laptop log do the same??

Lastly, the software has MAF calibration A and B while the log itself shows B1 and B2. Going to swap MAF's from left to right to see if it follows but anyone know how A and B matches up with B1 and B2?

A stock table would be a good starting point. Thanks in advance!!
