    I think the channel you selected if for a 30-0300, connected via the prolink.

    For now, the Pro Feature Set and ProLink is the way to go. The ProLink has it's own CAN interface that can recieve AEMNet CAN messages, used by the 30-0300 and 30-0310.

    I am, just now, starting a...

    Nope. They wont do that. They would rather sell you a 30-0300 :)

    I have to do that :)

    If you are dealing with 2007 or later vehicles, you can log wideband data with an AEM 30-0334, using the standard HPTuners setup.

    A 2000 Camaro ECU uses the J1850 protocol, not the CAN protocol. So, the 30-0334 can not communicate with it, via CAN/OBDII.

    A 30-0334 ca be re-flashed to be a 30-0300, which has the AEMNet CAN...

    The ProLink has CANBus. And, it will talk to the AEM 30-0300 and 30-0310 widebands, Along with a few that I have not tried. This is MASSIVELY superior to
    the serial data method.

    #1 What year is the vehicle ? If it is pre-2007. it may not be a CAN based ECU. In which case, the 30-0334 can not output OBDII data.

    #2 if #1 is OK, Did you add the WB from the AEM X-series...

    Leaving the sensor powered up, for long periods, in the open atmosphere, will degrade the sensor. But, that takes a good while.

    Leaving the sensor un-powered in a running exhaust will, also,...

    You can see AFR changes at the full 2ms. But, they do not get all the way to the actual target value until, at least 6ms. Good enough to pick out per-cylinder variations, on a scope.

    There is no...

    That is a bizarre sensor failure. It must be causing some kind if timing error. Probably some intermittent contactm doing something like a spark-gap, or something.

    So, something internal to the sensor must be shorted, in some strange way. This is, probably, all related.

    The odd part is that the same data is used for the Analog, CAN and serial data outputs. ...

    Not sure. I am just looking at the process of elimination.

    If it works on the bench. But not in the car. The only differences are:

    1. The sensor
    2. The wiring harness.
    3. The 12v power

    OK.

    I have not seen this behavior with the analog outputs. I will have to try some experiments. This happens only with the 30-0334 firmware loaded ?
    Is it possible that there is intermittent...

    Assuming that your ECU is CAN based ( 2008 or later, but, also, some earlier models ), the 30-0334 becomes part of the vehicle, so far as the MPVI2 is concerned. So the AFR/Lambda data shows up as...

    If you are using the X-series AEM wideband, you should use the CAN interface, rather than the 5v analog interface, if possible.

    1st thing is to make sure that you actually have a proper 30-0334. A while back there was a batch of 30-0334s that were shipped out with 30-0300 firmware.
    These can be distinguished from the normal...

    Just a note, here. It is very bad ( like drinking Jobu's rum ) to start an engine, with the sensor already heated up. If you MUST do that, to get startup data, you should use a wideband with an NTK...

    The 30-0306 does has CAN data. But, I don't think the CAN pins are populated in the connector. They are easy to add. But... I don't think VCMScanner knows how to read MAP data from AEMNet ?

    Bottom line is. There is no resistor in the 30-0334 harness. So, if your setup works without a 30-0334, it should work WITH a 30-0334. :)

    The gauges do not have terminating resistors. Those are somewhere in the vehicle wiring. It is, probably, integrated into 2 of the computers that are on the CAN bus. There are supposed to be 2 ...

    The 30-0310s can be programmed with the same OBDII patch as the 30-0300. I have done several of these. The caveat is that there is no user interface on the 30-0310. So, there is no way to change...

    That's a tough call. Some controllers do a better job of regulating sensor temperature than others, when EGTs change quickly. So, for those slower controllers, adding thermal mass, via a bung...
