    Default AFR is incorrect from FlashScan

    I use the FlashScan box routinely. This time when I start logging data I noticed numbers around 5.0 and in that range. As a cross check of the wideband, my analog meter is showing up correct as is the logworks.exe data.
    I also have a 3rd piece of software for logging the serial lc1 and its correct also.

    This happens where BBL or pass through. It also appears the font is smaller on the display now for the A/F.

    SO, is there a way to reset the FlashScan somehow? The serial data is wrong.
    Or is this one done for? I'm going to double check, but it also looked like the lambdas were correct, but a/f way off.

    TFZ_Z06,

    Is this with the LC-1 analog AFR (brown wire)...?

    Which AFR and BEN pids are you logging...?

    Do you have a DMM/voltmeter...?
    Connect one AA battery to the V2 inputs, see what V2 says, compare with DMM.

    Thanks for stepping in. I've noticed once or twice the LC1 has reset itself.
    I reprogrammed it for the right fuel and its back on track. Maybe I fumbled fingered the keyboard.

    I've had my LC-1's automagically reset once or twice before as well. The serial data follows the programming of the channel 1 output.
