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?

 

I know older versions of EvoScan had the low and high mislabeled ... your assessment of what should be changing and when is correct.

 

older...as in 2.1?

thanks for the response.

 

I can't remember if it was 2.1 or not. Sorry. But yeah, if high is changing and not low, just swap the request values for them in EvoScan.
