    Default Lexus is 300h F sport odometer help.

    Got an is300h with an eeprom that is bad. Won't program wont read properly. Decided the only way forward was to buy a new blank iC with a few spare given how cheap they are. Original is 93a66 but I'm led to believe that the 93c66 are almost identical from the datasheets .

    Problem: I need a dump from either a working cluster or an edited dump with adjusted mileage or something like that.

    But, it has to be for an F sport because the f comes with a different cluster than the normal is300h as it has a rev counter that moves to the right at the press of a button.

    The bytes on the chip (if wrong) cause all. Manner of craziness to the motor that moves the rev counter etc so that's why I need a dump for the is300h F sport.

    From what I can tell the is350 f sport is the American counter part but I'm not sure if they are the same cluster.

    Can anyone help I have a car stuck without this working and its a pain taking it in and out to test etc when it's all hit and miss

    Thanks

    Default did you try removing the chip

    try removing the chip from the board and see if you can read it that way
    is the dash currently working properly? or did your machine corrupt the data. Those ic only will burn if it's powered up backward

    At the moment the dash is working but the mileage started at zero.

    I need it to be 55, 000.

    I am using flypro and sofi sp8-a

    I could really do with a dump of a worker or file that's been altered intended for the same dash.

    See pic of which it is
