    Well, according to a back and forth email exchange i had with AEM tech support, the X series gauges all constantly output both analog and CAN buss outputs, and would have no issue connecting to both analog and CAN buss outputs, to the ProLink cable inputs. My concern was only that, I thought the ProLink cable still had some issue with functionality, and wouldnt read a CAN buss input from the AEM controller.

    The 30-0300 and 30-0334 use different CAN data formats.

    The ProLink CAN interface reads the 30-0300 AEMNet protocol. The OBDII port uses the 30-0334 CAN protocol.

    You can hook up the analog signals to the ProLink and get a good signal.

    If you want, the 30-0334 can be flashed back to the 30-0300 firmware. Which is the opposite of what is usually done.

    Bummer, did not know that. Otherwise i would have purchased the 30-300, learning curve i guess..... Now i gotta decide if i want to deal with it, or change it, didnt realize there were 2 different CAN protocols for that.

Just wanted connection options for logging.
    Since you have the 0334 just connect the two CAN wires to the OBDII port, and use standard HPT features, no need for the pro-link and anything extra to be hooked up. I have two!

    Why would you do all this when it's more work, more complicated, more hassle?: "was considering wiring both the CAN and Analog outputs from the 30-0334 to the ProLink, and doing away with the OBD2 adapter that comes with it."

    Well, because I wasnt planning on doing a permanent install, rather a portable one. Having the CAN and Analog channels in 1 cable to the ProLink, makes for an easier and cleaner use of cables. My thinking was to just select what input I was using in the VCM scanner, and to cut down on harnesses and connectors for portability. But now Im just thinking of using it primarily with serial,and just using the OBD2 plug for CAN logging if needed. This is all new to me and Im learning all of this, maybe the hard way, so I'm not sure what is the best use of the wideband via CAN, Serial or Analog. I like the idea of not having to mess with voltage offsets. CAN buss seems to be the best way for numerous reasons, but idk how well it works vs just using serial.

    As far as ideal signals, with thw WB it goes like this. ( Best to worst )

    1. 30-0300/0310 AEMNet CANBus signal via the ProLink. Fastest, most accuracy and range up to lambda 6.554. No ground offset issues or scaling math
    2. 30-0334/Re-flashed units OBDII CANBus via OBDII port . Still fast, Range up to lambda 2.000. No ground offset issues or scaling math
    3. All X-series WB Analog 0-5v. Actually even faster than CAN, if they ever further increase the polling rates. Range up to lambda 1.22 . Still no ground offset issues. But requires math setup.
    4. Serial X-series re-flashed. These WBs have an extra digit of resolution ( xx.xx ) and an upgraded polling rate ( 20ms, IIRC ).
    5. Serial X-series Stock. Only 3-digit resolution ( xx.x ) and slow 100ms polling rate.

    Sounds like I'm going to want mine reflashed. You still doing this?

    Half tempted to just buy another wideband, and use the 30-0334 as a permanent install into my Camaro.

    Hi dr mike and my other old hpt friends!!!

    My son just bought a C6 ZR1 so I'm going to clean up the tuning in it. I told him he'll need a wideband, so I go online to look at what's available since it's been years since I needed to buy one. I look on the AEM website and see the 30-0334 with it's cool pass-through OBD2 connector and full digital interface. NICE!!! That was all you dr.mike, with a tiny little bit of help from me maybe. It's pretty cool to see that product for sale on Summit, Amazon, etc, etc, knowing this forum helped develop it.

    Needless to say, I ordered one for tuning my son's LS9. Thanks again for all your efforts dr.mike. It looks like you're still active on here helping others too, good for you!

    John
    Check out my V8 Sky build video. It's pretty cool!...

    Yes. But, this would be the 1st 30-0334 being flashed back to be a 30-0300. On the other hand, I have a bunch of spare connector pins. So, I can throw a few in with the gauge, to make connecting up the new functions easier

    Hey John !

    I think you may have been the 1st Guinea pig for , what, eventually, became, the 30-0334 Yes, the AEM guys decided to pick it up as an option. I'm not sure people, here, actually, know that it started out as a forum project.

    Maybe you will be in on the next one

    The 0334 user manual sez it can be set for either 11- or 29-bit and either 250 or 500kb, has that been changed in recent models?
