Thanks, Do we (you, gurus) know why the LTFT High is zero for every log?

Because for the factory airflow range settings for the fuel trim crossover values, LTFT High is never accessed. Only Low (idle) and Mid (cruise) are accessed.

so if ltft_high is still being populated at 300Hz crossover, that crossover should be lowered a few steps, correct?
