BCFN is NOT in $5B4 as listed on here - the TCC vs Spark and MAT tables are all messed up.

There's more then that messed up in the XDF, some of the parameters address are off the chip?
There's always been some controversy over all the $5B XDF/masks and extra number on end. Since none of the one's I've seen have been signed and we don't have a hack for them I find them all questionable.
I think John at TunerCat is the only one who knows what they really are and are his designations? If it were a car I needed to tune I'd buy the correct mask from TunerCat.
BCFN was also superseded to BDHN which we do not have?

BCFN is attached. This was read directly from the Memcal.
Is there anyway I can check where the VATS flag should address too? Really all I need to do is turn VATS off. I would guess that the current $5B4 xdf may have the VATS address wrong.
Unless someone has a hack/dissasembly that I don't have? Then I would not know how to check and see where it is or what is accurate?

I have paid for the def from Tunercat but only after paying noticed on their site that they are closed for July 4th holidays.
5B4 XDF looks to be correct for BCFN. for some reason, the MAF tables 7 and 8 seem to be swapped?
i'm sure other little corrections are needed too, i know the later 5B stuff wasn't 100% accurate at times.
what happens if both the "VATS select" and VATS DTC are disabled?
With both disabled it runs for 1sec and shuts down.
