    OBDII Plugin Changes/Fixes - BETA Testers Needed

    Hello all,

    I am working on the current OBDII plugin trying to resolve some of the past reported issues that some users have experienced. Please help fix the OBDII plugin by testing the updated obdii.dll file (posted below) and posting back any issues or suggestions.

    EDIT: 6/9/2007 (Build 7, 9:30AM)
    * Added support for handling "SEARCHING..." responses from ECU.
    * Improved receiveComData() code
    * PID 0x1C now only sent once, that's all that's needed.
    * Screen labels now only update when screen is visible.

    EDIT: 6/6/2007 (Build 6)
    * Added timestamps to logging routine for easier debugging of user problems.

    EDIT: 6/6/2007 (Build 5)
    * Added another small fix to MIL processing code.
    * Fixed logging routine that was broken in last build.

    EDIT: 6/4/2007 #2 (Build 4)
    * Added support for reading more than 2 message responses from 1 PID request.
    * Added support for clearing DTC's. It really works now!
    * Info box popup when clearing DTC's showing error or success
    * Added processing support for PID Group 2, not used
    * Added processing support for PID Group 3, not used
    * Improved MIL handling

    EDIT: 6/4/2007 (Build 3)
    * Improved current code for reading MIL status

    EDIT: 6/3/2007 (Build 2)
    * First attempt to read multiple messages from multiple ECU's per PID (2 max)
    - Tested and working in a '06 CTS with 2 ECU's
    * More code cleanup
    * Fixed issue in handling of ECU prompts
    * Added more debug tracing for diagnosing user problems
    * Added code to clear log file when back from hibernation
    * Modified code to possibly ease burst CPU usage

    6/1/2007 (Build 1)
    * First updated release
    * Major changes and cleanup for better performance, save copy of original obdii.dll before using
    * Fixed issues in reading fragmented vehicle responses
    * Fixed issue with some PID's incorrectly being reported as unsupported

    EDIT: 6/9/2007 (Known Issues)
    * Report of connection made but no readings
    * Reports of MIL coming on/off intermittently when no DTC's are stored
    * Reports that on AutoConnect, connection drops after 10-20 minutes
    * Reports of plugin not working when coming out of hibernation
    * Reports of sporradic serial port disconnect
    * Reports of taking up to 2 minutes to populate all sensors with data
    * Logs showing "SEARCHING..." respnse, not handled by application

    The download is a ZIP file containing only the file obdii.dll. Place this file into the c:\Program Files\Centrafuse\Plugins\OBDII directory, make a backup of your original incase the updated version does not work for you.
    -------------------------------------------------------------------------------------
    NOTE: When dropping this in, be sure that if you want to keep the original DLL around, then you need to rename it to something like "obdii_v114.dll.xxx". If you use "obdii_v114.dll", then CF will load BOTH DLLs but only one will get the COM port. If the new one happens to be the one to get shafted, then it will not work. THANKS TO MIDIWALL for that tip...

    Hey man, would this plugin allow me to use an Accessport Cable and directly access the ECU info without the actual need of an OBD-2 Scanner ? That is my dream...because I can do it with other software...but to make it work in Centrafuse, I need the scanner. When I bought and tested an ELM scanner - I found its performance completely unsatisfactory.

    We are talking about a Subaru Legacy GT 2005 and my question addresses anyone with a Legacy 05-06; WRX and STi 2002-2006.

    Sorry, no, you need an ELM based device to work with this plugin.

    Updated DLL - Build 7

    Updated build, see post #1 for details. Added support for processing "SEARCHING..." response which seems to come from older model vehicles.

    I have a VW Jetta. I believe the controller I bought uses KWP-2000. Will Centrafuse's obdii software work with this?

    If not, should i buy something else? If so, what?

    Thanks in advance, this is a confusing subject for me.

    Hello MSCAPPA,
    KWP-2000 is one of the protocols of OBD-II standard, there is also CAN, ISO, PWM.....

    As long as you buy an ELM-based device with KWP-2000 support for your vehicle, you will be ok.
