    Thank you- very nice overview of STFT and O2 sensor, and the use of the Innova scanner !

    Long Term is the window of time the adaptive memory dictates the fuel trim, Short Term is live data calculating to learn the parameters for the adaptive memory to update the Long Term. The O2 sensor signals lean below .45 volts & rich above .45. The Engine Controller only cares about that threshold & uses that to determine fuel trim. .. in other words the computer calculates the % of time that the O2 sensor is past the threshold of .45 volts & does that each time the threshold is crossed.

    Hi, do you know the difference between "STFT B1" value (1:10) and "STFT B1S1" value (1:45)? Thanks

    So why did it throw the code?

    Hello sir. Magtatanong lang. Yung LTFT ko 0 lang kahit i-rev ko ng matagal hindi siya nagbabago. 15mins+ na nakasindi makina pero hindi nagbabago.
    May error na P0130.

      Hello @MotoArk ang P0130 error code ay indicator na sira ang bank1 oxygen sensor mo. It could affect the readings of the engine computer. Suggest na tingnan mo yung sensor by looking at the output waveform. If hindi mukhang sinewave, then papalitan mo na

    Good day sir, ano po pagkakaiba ng wide band sensor kompara sa narrow band sensor? Slmat

    You didn’t explain the long term 😢

      The LT Trim basically makes adaptation based on information from the STFT.. so it sets new baseline based on the data from the STFT.. so with the new baseline, the AFR goes to optimum
