Armed with the above information it appears on my first graph that the TRA2 is a bit rich at idle and the injector pulse width is being shortened as indicated by the -0.03. This is also supported by the yellow trace in the second graph showing the MAF value with the swinging 02. i do have a rich exhaust smell at idle. My next steps will be to run the set points and see how mine stack up, I will also run the test at 3000 rpm to see the change to the FRA/FRA2 trends. Possibly tomorrow since it is already 96 deg outside and ash is everywhere. I still suspect the MAF but will continue to attempt to verify. Thoughts?
