I am trying to tune the MAF. I am not planning on tuning VVE at all and just plan to run on MAF. Everything is turned off (fuel trims, DFCO, CFCO).
I am logging EQ error with NGK wideband. When I copy/paste the error, it either goes too far the other direction or barely makes a difference. I am trying to drive steady state on the highway to keep it in whatever cells for a long time. However, if I keep it in cells, they are not steady state, they will go from lean to rich or vice versa depending on which state they started in.
I have logged from a standstill and after driving a bit and stopped the logging before I let off the gas.
I have over 20 logs and tune variations trying to nail this down. Any help or advice would be appreciated.
