    Question Strange AFR from Serial ZT-2 -- OFF by Factor of 10!

    I recently changed from an Innovate LC1 to a Zeitronix ZT-2 serial wideband controller. Since the change I've noticed some strange AFR's when the ZT-2 is plugged in using the serial cable to the flashscan V2. AFR readings seem to be off by a factor of 10. For example when the actual AFR is 14.5 the flashscan will show 1.45 during BBL. I think I have everything configured correctly, but I've got to be missing something simple. I have the following settings:

    Com Port: Wideband
    Wideband: Zt-2
    Format: 1st wide band only
    Data Display: AFR only

    Do I need to create a calc PID or log a different pid for the ZT-2. I'm currently using EXT.WO2AFR1 same as I did for the LC1.

    Do the custom PID properties in V8 work with BBL? It looks like I should be able to adjust the output by a factor of 10, but changing these values doesn't seem to affect BBL or the logs. I know this would be a work around if it worked...

    Oh and thanks Joecar we the users of the forum appreciate the help!

    I've emailed Paul already based on your email to us. I'm sure it will be something simple

    Thanks for uncovering that bug. It was a fault in the FlashScan firmware. It will be fixed in the next update.

    Regards

    So does that mean it was truly off by a factor of 10? If so I can make a calc pid that simply multiplies the EXT.WO2AFR1 by 10 to get me by until the next release of the firmware?

    I would say it is going to be a presentation but, with the PID scaling simply being incorrect. You'be should be safe to create a CALC PID if you wanted. We are hoping to have a new firmware out pretty soon to correct a number of outstanding issues if you're not desperate.

    Does it have the option of Lambda/EQ?
    Lambda*stoich AFR=AFR
    stoich AFR/EQ=AFR

    You may even need to use analog until the next update.

    Did this ever get worked out?

    Mirage can you show me how you connected the Zt2 to the flashscan?
