DATA LINK MODULE-OBDII Thank you for purchasing the Dynojet Data Link Module-OBDII (DJDLM-OBDII). The DJDLM-OBDII allows data, such as spark advance, throttle position, head temperature, inlet air temperature, and numerous other parameters to be transmitted from the vehicle’s OBDII compatible Powertrain Control Module (PCM) via the vehicle’s data port. The WinPEP 7 software lets you easily view, save, and compare this data using just a few mouse clicks.

DATA LINK MODULE-OBDII DJDLM-OBDII and WinPEP 7 VIEWING THE RESULTS Data streaming from the PCM during the dyno run is available to be graphed right along side all of the standard channels such as HP, Trq, AFR, and rpm. This feature will be instrumental to assist you with troubleshooting, tuning, and maintaining consistency during dyno testing. Note: Rpm cannot be graphed on the horizontal axis due to the sampling rate from the vehicle sensors. WinPEP provides graphing of rpm on the vertical axis.
APPENDIX A DATA LINK MODULE-OBDII BASIC CONFIGURATION The appendix contains instructions for configuring the Dynojet Data Link ModuleOBDII (DJDLM-OBDII). To ensure safety and accuracy in the procedures, perform the procedures as they are described.
APPENDIX A Introduction INTRODUCTION ................................... There are four basic configurations for the Dynojet Data Link Module-OBDII (DJDLMOBDII). Each DJDLM-OBDII ships with the ability to be configured using any of the four methods described below. Dynojet recommends the DJDLM-OBDII be set up as a client on your wireless network. If this is not possible, it is recommended to use a direct connection to your dynamometer PC with a category 5 crossover cable.
DATA LINK MODULE-OBDII BASIC CONFIGURATION Introduction Category 5 Standard Cable—connects to your wired network with a category 5 standard cable. Refer to “Configuring the DJDLM-OBDII with a Category 5 Standard Cable” on page A-8 for more information. Figure A-4: Category 5 Standard Cable Configuration CONNECTING THE DJDLM-OBDII Once unpacked, a direct connection via a crossover cable must be made. 1 2 3 4 5 6 Plug the DJDLM-OBDII into a vehicle for a power source.
APPENDIX A Configuration CONFIGURATION ................................... This section describes the four ways to configure the DJDLM-OBDII. Changes made do not take effect until you save them and reset the DJDLM-OBDII. Dynojet recommends documenting any changes you make; this will make it easier to undo incorrect modifications should the DJDLM-OBDII not function properly. Tracking your changes allows for faster technical support of the DJDLM-OBDII.
DATA LINK MODULE-OBDII BASIC CONFIGURATION Configuration The Boot Options window will appear. You can begin configuring the DJDLM-OBDII. Figure A-7: Boot Options Window CONFIGURING THE DJDLM-OBDII AS A STAND ALONE WIRELESS DEVICE The stand alone wireless device is the factory default. This is a direct wireless connection from your dynamometer PC and the DJDLM-OBDII; no configuration is necessary.
APPENDIX A Configuration CONFIGURING THE DJDLM-OBDII AS A WIRELESS CLIENT Your wireless network must be running a maximum security of WEP with a 64 bit encryption. The wireless network can be open or shared, but "WEP security" is the highest security level available using the 64 bit encryption that the DJDLM-OBDII is currently configured to understand.
DATA LINK MODULE-OBDII BASIC CONFIGURATION Configuration 3 In the ESSID text box, type the wireless network name used in your business. The ESSID are case sensitive, be sure to match the case of your existing networks SSID. 4 Select Auto from the Mode drop down menu. You can statically define the Mode, however it is not necessary in most installations. 5 In the Key text box, type your wireless WEP key you have previously assigned to your wireless network.
APPENDIX A Configuration CONFIGURING THE DJDLM-OBDII WITH A CATEGORY 5 CROSSOVER CABLE The category 5 crossover cable ships with the DJDLM-OBDII. This is the fastest data transfer option available. No configuration is needed to the DJDLM-OBDII when using the crossover cable; just plug and play. 1 2 3 Power the DJDLM-OBDII on in the car. Attach the crossover cable to the Ethernet port on the DJDLM-OBDII. Attach the crossover cable from the DJDLM-OBDII to the dynamometer PC’s Ethernet port.
