Goal is to run consistently without too much fluctuation in fuel trims. Unless you're completely closed loop, then it wouldnt matter so much. Computer makes the adjustment fairly quickly under closed loop operation.
then keep ltft off during open loop, or zero the negative ltft only
or disable it and enable ecutek closed loop so to have always a perfect afr

anyway 13 afr on full load with e85 won t be such a problem
