I'm not an expert but I've exhausted my ability to learn about the sensor function operations so far, my questions are really toward how ME7.2 manages the information.

My plan is to modify the nbo2 sensor readings back to the dme in order to run rich.

The reason i asked whether the maf checked the nbo2 or vice versa is because the explicit logic that me 7.2 uses is not described anywhere that I can find and it will impact the design of my system.

If the NBO2 is the "trump all others" measure of fuel mixture settings in closed loop operations, then I can create a voltage divider to accomplish this task.

If the NBO2 readings are of secondary importance, then I need to focus moreso on modulation of the MAF output with an opamp and just feed back a constant .45V to the nbo2 sensor pickup at the dme.

The second approach would be less complicated but I don't think that it would work if the computers logic is centered around a [greater than or less to 0.45V execute x func] since the dme REQUIRES fluctuations, as opposed to a system that is shooting for a specific operational value range that it is constantly adjusting the variable outputs (i.e. fueling) to stay within.
