    Default AEM 30-0333 wideband canbus

    Are there any threads discussing the new AEM wideband that connects directly into the OBD2? AEM says it's been varified to work with EFILive but my search came up empty handed.
    I'd like to daisy chain 2 of them and log with the V2.

    EFILive does not support reading the wideband indirectly from the CAN bus.

    EFILive supports reading the wideband directly using serial comms.

    FSV2 will support 2 daisy-chained AEM's if they have serial in and serial out... but they do not have serial in.

    edit: AEM 30-0333 only has serial out.

    It's very disappointing EFILive doesn't have this capability.
    Also very misleading that AEM suggests it does work on their website.

    Can you send me any links to any information about that wide band controller's OBDII capabilities?
    I'll investigate what it would take to support it.

    I did some digging and it appears the wide band controller still has the serial output. I presume you can still connect it to FlashScan using the serial option.

    Here are a few pages from the instructions found on the AEM website.

    The OBD2 integration would be really nice.
    Hate for HPtuners to only have this capability. lol

    For use with V7, the serial interface is the preferred way to log the wide band data. That's because the V7 scan tool can only log data from a single OBDII controller at a time.
    The V8 scan tool can log data from 2 OBDII controllers at the same time, so it may be something we can implement in the V8 scan tool. Until that option is implemented, using the serial interface is the appropriate way to log wide band for use with EFILive data from the AEM controller.

    Makes complete sense Paul, I know that's one limitation you're removing with the V8 scan tool. I'd advocate for it as well, it removes the ground offset completely and supports the same sampling rates as OBDII/CAN. Still, love the serial input option on my LC1 and V2!

    Nail on head "removes the ground offset completely and supports the same sampling rates as OBDII/CAN"
    Would be very much worth it.

    i purchased 3 of the new units recently myself and have just been using the serial output. sadly it only has 1 serial out, so u can't daisy chain them.

    supposedly you can do it through the can wires, but im not sure it'll output both via 1 serial.
