2015 Z06, full bolt ons, 2.31/9.5 pulley combo, on E30. I got most of my throttle/tq tables straightened out but now the car will go in to REP just before 84 lb/min. There has to be something I am missing here. To add this is the most airflow I have scene since adding the lower. It has to be a table I am missing.
There is a difference in the measured maf airflow lb/min compared to the map airflow lb/min which sets the code.
You have to tune your vve until its airflow is equal to the maf calculated airflow.
If you want a band aid fix; max out the maf/map correlation P0068 tables under engine diagnostics under airflow and set the following codes to no error reported + no ses:-
P0068
P2281
And any code that relates to TPS that show up afterwards.
Curious if/how this was resolved because I had noticed you were not getting desired fuel pressures so was curious if that was also an issue or just a victim of the diag codes.
