Default A9L MAF, error code 56

I'm getting this code and, of course the check engine lite is on, but there doesn't seem to be any problelm with my MAF sensor. It's brand new and I have inserted all the new flow data into my file. I'm using a Snap-On scan tool to retrieve this code. Can the new MAF flow data be the cause for this? Has anyone else had a similiar problem? If this is normal after inserting new MAF data, is there some way of turning off the CE lite? I've cleared the codes repeatedly and it comes right back.

Also, I did change the maximum MAF_VOLTAGE to 4.90, as per the Pro-M data sheet. Could this be the problem?

Any help or opinions appreciated.

Paste your MAF table, let me take a look at it first.
Also tell me what size MAF it is.

Well, here's what I found. I wasn't sure how to get a good printable file so I went through some contorsions and ended up with this Notebook txt file. There appears to be something strange happening there within the table, like it repeats part of it. Tell me what ya' think.

There are other changes that I've made and I'm taking it slowly. Any suggestions would be appreciated. The injector size is 30# and the MAF meter is new.

Thanks again,

Larry: can you send me the EECtuner file? or are you using the GUITuner program.

Also..what size is the PROM MAF?

Well, lets see here......... The MAF is a 75mm Bullet.

Here's the .cal file, renamed to .txt so I could post it.

I almost forgot, I'm using the GUI software.

GTRaptor, did you find anything out of the norm with my file? I hadn't heard anything back so just had to ask. Pardon my impatience.
