In the tuning SW I have seen, there is only a single MAF table (total voltage=total amount of airflow). The service manual is not very clear about what the ECU actually does. In the diagrams, it looks like it is eventually treated as a single value. It looks more like the "bank 1" and "bank 2" reference is more for identification of each throttle body.

I'm not sure what brand they are. S&R ordered them for me.

Thank you for the reference! With the way the VQ35 motors were, I was under the assumption that the air did disperse from the upper plenum into the lower plenum, then into the runners. It doesn't look to be that way in the VQ37s. The good thing is I was watching the AFRs when we were street tuning and the AFR from each bank is nearly identical. It was off by maybe 0.1 at some points.

I thought the same thing based on the VQ35DE, but I was surprised at the way the runners were setup on the VQ37VHR manifold. I am sure the airflow is equalized at some point, and the fact your AFR's were that close indicates that is the case.

Most people use the HPX MAF sensors (this is what UpRev recommends/sells).

Anyway, good luck. I am sure you will get it sorted out. You obviously have some good people supporting you, and these are pretty minor bumps in the road for a custom setup.
