ok let me look into this. I do think that the 2009 ECM is the e40.
I am comparing a 2006 ls2 to a 2006 ls7 and both have two MAF tables, a high and low and follow the same points. I even compared all the data under engine diagnostics and they all match between the two.
Note that I am running a MAF only tune so also looking into whether there is a DTC that needs disabling. However it that was the case I would think I would have thrown the code right away. Even if the data is wrong and off by that amount I would think it wouldn't run and throw the code right away. Who knows maybe it got dirty or going bad. Thanks again
Depends on where the other end of that line goes. Any line in front of the TB blade as part of the PCV system should be going to a valve cover nipple.
I take this back. I am running mighty mouse's draft catch can so I have one hose from the valve cover going to the can and the hose from the CAI also going to the can per his instructions.
so haven't made any changes yet. I reset the code, pulled the MAF sensor, cleaned it, removed a sticker that was on it, tighten everything down to eliminate any possible leaks, reset the fuel trims and have been driving it. It runs good, my fuel trims are off but it runs and hasn't thrown the error yet. It didn't throw it last time until after many track runs.
Can someone confirm that this is the right function to use for Lambda error for the MAF. I used this for my VE.
8-13 rich. I thinking thats because the ZO6 mf table is for a ls7 vs ls2 so a lot more air. But keep in mind i'm still verying that the histograms are set up properly. I say that because my lambda error is small. If i'm commanding 1 and gettin .98-.97
dialed in my low MAF table using LTFT. Here is what they look like.
Here is my theory. I loaded the MAF table from a ZO6 which we know is a ls7 427 vs a ls2 364. So my computer was thinking it needed more fuel than required (I pulled a lot) as it was calling for so much air volume. And that is what threw the PO101 code that the MAF was out of range.
Now, if this theory makes sense, then I still need to tune the high table which I will do via my wide band and lambda error. Then I need to run it hard again as that is what I was doing when I threw the code last time.
so I tuned in my VE using the bluecat tool and LTFT, very cool tool. I now have the MAF low table and VE dialed in (need a little work on idle but not bad) and next will tune high MAF and WOT using wideband and lambda error. Once I get that done I hope not to throw the PO101 code any more.
DRAFT is not a PCV system, there is no fresh air inlet on DRAFT, therefore everything going through the maf is fresh and accuratley measured. All good!

The 06 OS has a limit of 512 g/sec. The 08 is much higher limit. You can increase this by upgrading the OS... I would think the max you are seeing is probably normal for you mods.
And the arrow goes towards the throttle body. It is showing the direction air should flow through the maf.
