    Just to clarify the situation.

    EFILive/FlashScan correctly implements the OBDII standard with respect to the "keep alive" timing.

    The AEM firmware does not implement the OBDII standard with respect to the "keep alive" timing.

    Once the AEM firmware has been updated to use the correct timings provided for in the OBDII standard it works correctly.

    2. To get it to stop "freezing" with EFILive V8, the firmware has to "technically" violate the OBDII protocol standard. So, it would be "non-conforming". i.e. are you allowed to call it OBDII compatible, if it, technically, isn't ?

    So, I do not know if they will incorporate that patch into their production code.

    On the plus side, the patch seems to have worked for everyone who has tried it. And, since EFILive is running the bus, and does not mind the patch, everything seems safe. But, if a different scanner were attached, that needed everything to conform to the standard, it could, possibly, break something.

    If you want to send your gauges to me for re-FLASH, send me a PM.

    Oh, also, the patch improves the 30-0334 serial data connection. With faster updates and an extra digit of accuracy, if you ever need to go that way. So, there is that
    So as I understand any body have the freeze problem with Efilive have to send you the gauge for firmware update ?
    Will this be updated in the new devices if I purchased ?!
    Or it will be always lile that unless we need it updated from you ?!!
