    Default AEM X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge

    Can efilive log the WB data thru the OBDII connector? Also will it support 2 WB's? It says it will following the link

    http://www.aemelectronics.com/?q=pro...and-uego-OBDII

    The AEM response time is about 20ms in the attached table, LC-1 37ms and the LC-2 85ms

    I wonder if innovate will go this route. I was a little surprised to see the LC-2 T63 response time was a lot slower than the LC-1.

    it still uses the same data protocol as the older ones so yes they do work.

    the 4.9 sensors absolutely shit all over the 4.2s for data collection.

    FSV2 logs directly from the WB, not via CAN LAN/bus.

    If the WB is on the CAN LAN/bus (i.e. and has an id), then I can imagine FSV2 would have the capability to read pids from it, but at present EFILive only reads pids from PCM, ECM and TCM.

    Yes I believe that's how HP is logging thru the obdii, uses standard I'd

    The lc-2 uses the 4.9, lc-1 the 4.2 and it's faster, the aem uses 4.9 and it's faster than the lc-1, Innovate have some catching up to do.

    Also HPT when used with aem over the can bus can poll 100hz, serial connection polls 10hz I believe?

    i asked for the capability to get the canbus data and got shot down. at least for now.

    I thought FSV2 can read the serial comm at the same rate as the pid logging, i.e. 10Hz for LS1, 40Hz for E38/E67.

    The polling rate is what has peaked my interest, between serial or Canbus and the FSV2 and between FSV2 and the PC?

    Can FSV2 softwares support Can bus 100hz polling?

    Here is a post made by Dr.Mike on the other forum, he appears very knowledgable and tests Lambda WB performance, worth while reading any of his forum posts.

    Hi all.

    I have just finished up a re-flash mod for the new AEM 30-0300 "X-Series" gauges. It swaps out the AEM CAN data format for an OBDII/PID interface that works directly with VCMScanner 3.0.

    Basic features.

    1. The Lambda data shows up just as if the car was equipped with it from the factory, as PID 0x24 through PID 0x2B.
    2. It has been tested with the new 3.0 release of VCMScanner at the full 100Hz ( 10ms ) polling rate.
    3. VCMScanner supports its free-air calibration controls.
    4. No voltage offset and scaling issues. No analog noise.
    5. The gauge is actually designed to produce data at 500Hz. So at the max 100Hz rate, you are getting real data.

    I am looking for a couple of beta testers. If you send me your 30-0300 ( just the gauge), I will flash the mod'ed firmware onto it and send it back.

    It does need to be wired into the existing OBDII port wiring. But, that's not so bad For non-CANBus cars, you will need to use an OBDII splitter cable ; since the OBDII CANBus pins will not be present in the vehicle's connector shell.

    PM me, if interested in trying it out.
