Default Problems with block 32

Hello, until yesterday I had Dtc 17536 and 17538, trim too lean. I Changed the Maf and made an adjustment basic of block 060. I scanned 032 block and these are the values:

<a href="http://img354.imageshack.us/my.php?image=mafnuevo3ls.jpg" target="_blank"><img src="http://img354.imageshack.us/img354/1272/mafnuevo3ls.th.jpg" border="0" alt="Free Image Hosting at www.ImageShack.us" /></a>
and this is the graphic of the mafs:

The problen is the secon file block 32 says 0.0, Why? need more time for adaptation?

Old maf: With dtcs; 17536 and 17538.

New maf: No DTCS AUTOSCAN

Default When you clear fault codes, both reset to 0.0

It takes some driving time for fuel trim values to be registered.

Default Why do you consider this to be a problem?

Values close to 0 are good!

Default I wouldn't let that bother me unless it throws some DTC.

How many miles have you put on the car since you last cleared fault codes?

Default 3 miles isn't near enough for those numbers to be meaningful.

Drive the car for a few days, including some time on the highway, then check 'em again.
