Newbie here trying to decode a 93c66 in a 2006 Tundra. Accidentally messed it up while trying to change odometer reading. Apparently in this vehicle there is info stored in this eeprom for both the tachometer and speedometer operation in addition to the odometer mileage. I'm guessing this is used to calibrate them or alter settings for different engines or drive trains. Anyway I have a flashing odometer and no tach or speedo operation. Need to get info back in the chip. Any help would be appreciated. Thanks, Thomas
