Was wondering if anyone had an explaination of why the two different choices under the DTC Process Enablers. Example - I want to go SD, so I set the MAF DTC's P0101-P0103 to anything BUT X: Not Reported and then set appropriate values under the MAF parameters, (C2901, C2904, etc..). If I had picked X: Not Reported instead of say, C: Non Emissions, apparently, the PCM does not fail the MAF, and it still keeps looking for it, thus affecting the engine air flow calculations.
If this is true, then what is the different between these two. I would have originally though that selecting X: Not Reported would turn off this poriton of the code and taken it out of the loop. Reason I am asking for the clarification, is that I am building a stand alone setup without, MAF, Cat's EVAP, etc... Just wanting to understand what all is needed and how it affects the code to make sure it is doing what I think it is doing.
