    These cheap devices are a scam. Not a real elm327 chip but a pic microcontroller emulating an elm. Really slow connection speeds. 38kbps. Waste of money.

      Umm, the "real" ELM327 is a pic microcontroller too. Quote: "The original ELM327 is implemented on the PIC18F2480 microcontroller from Microchip Technology" from http://en.wikipedia.org/wiki/ELM327

        The original may be, but the new ones are their own chip. They cost $21 each.
        Don't support fake chip makers who produce crap. Buying this is the same as downloading a Movie or TV show from a torrent.

          I think you'll find they are still a programmed PIC18F2480 microcontroller. Here's the ELM327 (latest version) datasheet from ELM electronics:
          http://elmelectronics.com/DSheets/ELM327DSH.pdf
          Here's the datasheet for the PIC18F2480:
          http://ww1.microchip.com/downloads/en/DeviceDoc/39637d.pdf

          Check the pinouts. Notice how the MCLR, OSC1, OSC2, RX, TX, VCC and both VSS pins are on exactly the same pins? And ELM even names pin 1 as MCLR, which is pretty specific to PIC microcontrollers, most others call that function "RESET" or "RST".

          I half agree with you about the IP issues. But as all the chip is doing is performing a transcoding from one protocol to another, and all of the protocols are fully documented, it's a bit like FTDI saying "we produced the first serial-to-USB protocol converter, nobody else should be able to make them". Well, several other companies DO make equivalent chips.

          The hard part is that you can't really tell if they copied the code, or if they wrote it from scratch, just like ELM did. That they are saying "ELM327" on the front of the box could be construed as a mark of compatibility, rather than a claim that the box contains a genuine chip.

          So it comes down to "ELM did it first, using publically-available documents to make their chip do a useful function". The question is, should they be granted perpetual rights to be the ONLY producer of similar devices? Comparing this with something like the Windows-versus-Macintosh lawsuits, it seems not.

          That makes sense. But there definitely something broken in these cheap versions as they only support The serial interface speed of 38kbps. This is not even fast enough to monitor the more than two or three sensors at once.

          The full price cables allow something like 500kbps or higher.
