<h1>ECMLink - Speed Density Setup</h1> <div class="level1"> <p> This page describes the basic process for getting your car setup for speed density operation with ECMLink. If you need a more general speed density tutorial, then the <a href="/wiki/doku.php?id=sd101" class="wikilink1" title="sd101">Speed Density 101</a> page may be what you're looking for. In fact, we're going to assume you already know everything off that page as we discuss items below. So it might be a good idea to read over it even if you're already pretty familiar with SD in general. </p> </div> <h1>Connecting the Sensors</h1> <div class="level1"> <p> The first step is to connect your sensors to your ECU. You'll need a GM IAT sensor and an absolute pressure sensor. The following table lists the supported sensors. </p> <span class='np_break'> </span> <div class="table"><table class="inline"> <thead> <tr class="row0"> <th class="leftalign"> Sensor </th><th class="leftalign"> Desc/part number </th> </tr> </thead> <tr class="row1"> <td class="leftalign"> GMIAT </td><td class="leftalign"> GM Intake Air Temperature P/N 25036751, pig tail 12102620 <a href="http://www.gmpartsdirect.com/" class="urlextern" title="http://www.gmpartsdirect.com/" rel="nofollow">GM Parts Direct</a> </td> </tr> <tr class="row2"> <td class="col0"> GM 3-bar </td><td class="leftalign"> GM 3-bar P/N 12223861, pig tail 15305891 <a href="http://www.gmpartsdirect.com/" class="urlextern" title="http://www.gmpartsdirect.com/" rel="nofollow">GM Parts Direct</a> </td> </tr> <tr class="row3"> <td class="leftalign"> GM 3.3-bar </td><td class="leftalign"> P/N 9373269, pig tail 88987997 <a href="http://www.gmpartsdirect.com/" class="urlextern" title="http://www.gmpartsdirect.com/" rel="nofollow">GM Parts Direct</a> </td> </tr> <tr class="row4"> <td class="leftalign"> AEM 3.5-bar </td><td class="leftalign"> AEM 30-2130-50 (50 PSIA / 3.5 Bar) </td> </tr> <tr class="row5"> <td class="leftalign"> AEM 5-bar </td><td class="leftalign"> AEM 30-2130-75 (75 PSIA / 5 Bar) </td> </tr> </table> <span class='np_break'> </span> </div> </div> <h1>Configuring the Software</h1> <div class="level1"> </div> <h1>Dialing in the VE Table</h1> <div class="level1"> </div>
