    Set MAF Freq Fail High to 0, set DTC P0101-103 to fail on first error, set Lo octane spark table to Hi octane values (when maf fails pcm reverts to lo octane table), set MAF High RPM enable to 8000. You will tune the secondary VE (same, pcm reverts to it when maf fail) and when done copy over data to primary and interpolate in the missing data.

    work the Engine Diagnostics>General and Airflow....increase the pi06, p1514 etxc values etc test tables. Multiply by like 1.5 for each. Do you log anything? If so what and why?
