fuel trims in logs mislabelled?
please excuse me if this is a dumb question. Is there any reason my fuel trim column labels in my logs in excel dont match what they should be? My Closed Loop - LT Fuel Trim Control table shows what I think are stock values
low-mid 75
mid-low 62.5
mid-high 1587.50
high-mid 1581.25
for the crossover points. I am idling around 30hz, and the way I understand it, LTFT Mid doesnt get used until 75hz with the values I above. When I look at my logs, Im seeing LTFT High changes, LTFT Mid changes, no LTFT Low changes (.1008), and STFT changes. I checked back on some older logs and honestly think its always been like this, or at least since '07 (or '08) with a V5.1 map-maf patch. Is this a known issue thats not showing up in a search? Or something else?
