5.2L V10 MAF logging
Is there a way to simultaneously log both MAFs?
The description for Blocks 77 & 78 look like they could be for each MAF but when logged they look identical.

Since this car has two ECUs, it's not possible to log both MAFs simultanesouly. One MAF reports to one ECU and one reports to the other. To check the readings, you need to log each one separately and then add them to together. Basically, one ECU monitors the passenger side of the enigne and the other ECU monitors the driver side. It seems like the Engine ECU does a little more than the Engine II ECU but I guess one of them needs to in charge.
Per Uwe at RossTech you can log block 31 on the Engine module through VCDS to view all of the O2 sensors at once but there isn't a way to see the MAF both sensors together.
