  • Looking for Non ELM software for OBD II

    Hi,

    I am driving on Fiat Punto HGT 1.8 16v 2002.

    It does support OBD-II (ISO), but i can't find software that supports the "direct" obdII commands.
    The only software that does it as i know is VAGCOM, but it is limited for VAG cars only.

    I tried the ISO-9141 active-x tester and it works ok with the converter i built,
    but i'm looking for real software and not a tester.
    All other software i know are for ELM.

    does anyone have an idea?

      Hi,
      What is wrong with the ELM hardware? And what do you mean by "direct" OBD-II?

        This one is non-Elm and there is a special version that supports direct ISO. So I'm assuming that the software that comes with it will work with it.

          Hi,
          ELM hardware is over priced, and not so simple to build, while direct-ISO is very simple and i have it ready and built.

          direct means that the PC serial port talks directly with the ECU and not trought an interpreter like ELM, which is a sort of modem emulator..

          for example, VAG software doesn't work with ELM, but using direct pc to iso.

          wi77iam, thanks for the link, i will try that.

              It should be mentioned that the society of automotive engineers has a PassThru standard (SAE J2534) for vehicle network interfaces. You're right to criticize the ELM hardware -- it doesn't comply with the SAE standard. It also has poor control over message headers, init sequences, P timers, and does not work with OEM controller reprogramming software.

              My company DrewTech is announcing the Mongoose ISO/CAN tomorrow at Testing Expo 2005. The Mongoose is a low-cost full-speed USB (12mbps) interface. I'll have more details and pictures posted on our website after the official announcement. If you're unfamiliar, I have a J2534 programmer's overview posted on the website. Similar to a printer driver, it defines a standard driver for vehicle network interfaces. Both PCMScan and Digimoto are already adding support; others are starting.

              I know this this might not answer your question if you're looking to build your own hardware. But maybe this is something interesting to you? Any questions feel free to email or followup.

                Mongoose

                I couldn’t find any info about Mongoose, what is the status please.
                Thanks

                  looking at it strictly from a "consumer" point of view only, could anyone explain this to me in plain english as to what is really the advantage to the consumer for buying something that costs twice than some (and equal to some) other options available.

                    Hi Lloyd, thanks for the prompt and useful response.

                    Yes I want to read, log and analyse real-time sensor data. Mode 06 results and enhanced PIDs as well, but I guess enhanced is not an option yet on a Honda/Acura vehicle(?)

                    Seems like the major difference here is speed. 'Speed' as in the number of times the hardware/software is capable of pulling data from the sensor, right ?
                    Then how much difference are we talking about ? Lets say I'd like to read and/or log one particular sensor then what is the real-world speed difference between a typical ELM based interface and a J2534 based ? I'd imagine that would also change the number of samples you would see simultaneously ?

                    I didn't quite catch all from this.
                    So if the car is pre-2004 it doesn't matter whether you use ELM or J2534 ?
                    And J2534 allows reprogramming anything in any ecu ?
                    Will J2534 allow access to enhanced pid's that are still visible only to proprietory systems (honda again) ?

                    and thats why we turn to you to provide us as much information as possible so as to make the right decision. Thanks!

                      The Mongoose ships with a DLL file that will extract all the data from every parameter command currently passing through your car's network. The information is right there if you know what to do with it. Combined with the diagnostic capability of PCMSCAN you can probably work out every parameter you're needing to evaluate.
                      Very interesting, but by "every parameter" do you mean "generic" parameters only or "enhanced" parameters also ? It is very important for me to know this difference.

                        PCMScan supports generic parameters like almost all low-cost software on the market. It also has a monitor prompt to send messages manually.

                        If you write custom software, I have sample code and it's relatively simple to access the enhanced parameters.

                          Now you have my attention! That is really very exciting, it opens up a whole new dimension in my quest for a good obd-2 scanner.

                          Software programming is my real job. Currently I am doing database programming (oracle pl/sql), but I just loved programming in C and Assembly.
                          Long story short, I would certainly like to see the sample code (and any further guidelines you could offer).
                          Thanks!

                            Hi there, I'm driving a suzuki swift and have built a direct Serial to ISO9141 interface. I'm having some difficulty with software. Cant seem to connect to my ECU on the K-Line.

                            Any advises....
