Please look over this log file and tell me what you think?
I keep getting multiple misfire codes and lean condition in both banks 1 and 2.

First thing, you need to get your LTFTs slightly negative with a MAF Translator or LS1 Edit. The Granatelli MAF isn't helping I don't think; I would put the stock MAF in and richen the LTFTs, then you can worry about the O2s and PE/WOT a/f ratio.

How do I get my LTFT's negative? I do not have LS Edit, but I do have EFI Live V5, so I can make changes while plugged in.

Thanks

I will change my MAFS back to stock.

The only way I know to make permanent changes to your pcm is either a MAF Translator, a Predator, or LS1 Edit. EFI Live is a diagnostic tool that I thought could make temporary changes only. Correct me if I'm wrong. The MAFT has a base (LTFT) and a WOT setting; LS1 Edit has tables that you edit; for example, MAF table, Injector Flow Rate, and PE vs RPM (Power Enrichment).

I think you need to decide if you want purchase one of the editing tools I mentioned, or have someone tune your car for you. I swear by LS1 Edit, although it takes quite a bit of research to figure-out what you're doing. The Predator is more user friendly but is limited compared to Edit. If all you need to do is just adjust your LTFTs and PE/WOT a/f, why don't you just get a MAF Translator.

James we were in such a hurry I forgot to tell you yesterday when we looked at your MAF sensor, we should change it back to stock and do the runs again. I know it can be contributing to your problem.

Yes, your right. Tonight I am going to put the stock MAFS back on.
Like I said, last time I went to drag race, I had changed the MAFS to see if it would help my times, and then I forgot to put the stock one back on

Tonight I will change the MAFS and then do some more logging.
