    Thanks. I made a hasty decision, but was able to cancel the order for the 0334. Is the 0333 the best choice for the non CAN (0411 and similar) PCM's in your opinion?

    Thanks for the info....I'm trying to get started logging and trying to tune my truck.

    Yes, if you never plan on an E38/E67/E92 (i.e. CAN-bus) vehicle.

    The 30-0300 is the one with all of the non-CAN functions available on the wiring harness. The old 30-0333 is the same as the 30-0334, but without the updates for EFILive. (i.e. mostly, for "brand H" scanners )

    ok, just to be clear:
    30-0300: analog 5V, serial comm.
    30-0333: analog 5V, serial comm, CAN-bus (EFILive can read only one 0333 on the CAN-bus)(HPT can read two 0333's).
    30-0334: analog 5V, CAN-bus, dual cascade-able for EFILive (EFILive can read two 0334's on the CAN-bus).

    almost:

    30-0300 is the original part. Its CANBus interface is used for AEMNet communication. It has wires on the harness for 0-5v and serial data. It has CAN wires. But they are NOT programmed to do OBDII. It is, usually, the cheapest.

    30-0333 The 1st OBDII compatible unit. Worked mostly with HPTuners. Ships without the pins for 0-5v and serial installed in the harness. I need to double-check if the serial data function is present. I know the 0-5v is there.

    30-0334 An updated version of the 30-0333 that adds support for EFILive . It allows for the dual channel mode.

    There was an interim development version of the EFILive compatible unit that was never released. It was the one that only supported a single channel. The dual chan mode is a bit of a trick. Hence, the delay getting it out there.

    If you don't have a CAN based PCM ( and dont plan to get one ), get the 30-0300 for the complete wiring harness. The 0-5v output is, actually, excellent. The active ground offset compensation all of these WBs more accurate than any non-compensated units. But, then, the subject of WB ground offsets deserves its own thread

    Thanks dr.mike, and you too joecar!

    I'll order the 30-0300, unless you would recommend a different WB since I'm not tuning any CANBus vehicles at this point. I'm just trying to tune a spare truck, and then my Camaro, both which are 0411 swaps.

    Yes. The 30-0300 makes the most sense, in that case. Or, the 30-0310, if you don't want the gauge. In either case, you get the fast response time, and, the corrected analog 0-5v signal.

    Dr. Mike I have a few questions for you regarding this topic and sent you a message last night. I have everything connecting to monitor 1 sensor however the pids are extremely slow to respond. While trying to monitor the data I have to hold the mouse over the PID for the numbers to change. I have no doubt that I am missing a setting or have something configured wrong but just dont know what it is. I have checked all the settings I read about and everything looks correct. Im hoping you or someone else on this thread has some step by step instructions on making this sensor function with EFI Live so I can log this truck. Thank you in advance for any help.

    Dr Mike , I can’t seem to make the calculated pid for the 30-300 show up on 7.5 scan tool . What am I doing wrong? I the calculated pid text in the folder but it doesn’t show up when I open the scanner . Just the pre loaded units are in there.
