no , should be no more than about .1 less than fn875 for your idle rpm

not uncommon but so long as its not a major correction

Fn875 is set to 1.00

Reading the parameter comments on Ithbma I converted the maf flow at idle from kg/hr to lbs/min and came up with .918, so that’s what I set it to. Does that sound right?

What effect will this have? Because I’ve run this car for years with it set at zero? lol
