<h1>Overview</h1> <div class="level1"> <p> This page is only intended to list out the basic items required to run speed density with ECMLink. If you need help with configuring ECMLink for SD operation or you want to understand more about SD, the following pages will be more appropriate for you. </p> <ul> <li class="level1"> <a href="/wiki/doku.php?id=sdsetup" class="wikilink1" title="sdsetup">Speed density setup with ECMLink</a></li> <li class="level1"> <a href="/wiki/doku.php?id=sd101" class="wikilink1" title="sd101">Theory and general speed density overview</a></li> </ul> </div> <h1>Sensors</h1> <div class="level1"> <p> At a bare minimum, the ECU needs to read manifold pressure in order to estimate airflow while running speed density mode. </p> <span class='np_break'> </span> <div class="table"><table class="inline"> <tr class="row0"> <td class="col0"><a href="/wiki/lib/exe/fetch.php?tok=185705&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fgm4bar.png" class="media" title="http://www.ecmtuning.com/images/gm4bar.png"><img src="/wiki/lib/exe/fetch.php?w=100&h=100&tok=bdc7e0&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fgm4bar.png" class="media" alt="" width="100" height="100" /></a></td><td class="col1"><a href="http://www.ecmtuning.com/product_info.php?cPath=28&products_id=47" class="urlextern" title="http://www.ecmtuning.com/product_info.php?cPath=28&products_id=47" rel="nofollow">Basic MAP sensor with pig tail</a></td> </tr> </table> <span class='np_break'> </span> </div> <p> In addition, you really should consider running an intake air temp sensor as well. </p> <span class='np_break'> </span> <div class="table"><table class="inline"> <tr class="row0"> <td class="col0"><a href="/wiki/lib/exe/fetch.php?tok=0d03fe&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fgmiat.png" class="media" title="http://www.ecmtuning.com/images/gmiat.png"><img src="/wiki/lib/exe/fetch.php?w=100&h=100&tok=2b4a5e&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fgmiat.png" class="media" alt="" width="100" height="100" /></a></td><td class="col1"><a href="http://www.ecmtuning.com/product_info.php?cPath=28&products_id=49" class="urlextern" title="http://www.ecmtuning.com/product_info.php?cPath=28&products_id=49" rel="nofollow">Basic IAT sensor with pig tail</a></td> </tr> </table> <span class='np_break'> </span> </div> <p> If you want both at the same time, we have an "SD Bundle" on our website that discounts the combination. </p> <span class='np_break'> </span> <div class="table"><table class="inline"> <tr class="row0"> <td class="col0"><a href="/wiki/lib/exe/fetch.php?tok=195524&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fgmiatcombo.png" class="media" title="http://www.ecmtuning.com/images/gmiatcombo.png"><img src="/wiki/lib/exe/fetch.php?w=100&h=100&tok=b7bb4a&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fgmiatcombo.png" class="media" alt="" width="100" height="100" /></a></td><td class="col1"><a href="http://www.ecmtuning.com/product_info.php?cPath=28&products_id=50" class="urlextern" title="http://www.ecmtuning.com/product_info.php?cPath=28&products_id=50" rel="nofollow">SD Bundle with MAP and IAT with pig tails</a></td> </tr> </table> <span class='np_break'> </span> </div> </div> <h1>Plug and Play Cable</h1> <div class="level1"> <p> The sensors above include loose connectors with pig tail ends that you can solder into your wiring harness. </p> <p> If you prefer to plug the sensors directly into your MAF connector, we do have a plug-and-play cable for that. </p> <p> <a href="http://www.ecmtuning.com/product_info.php?cPath=26&products_id=52" class="urlextern" title="http://www.ecmtuning.com/product_info.php?cPath=26&products_id=52" rel="nofollow">SD plug and play cable</a> </p> <p> The only thing that should be mentioned here with the plug and play cable is how use of that cable may affect your dial in proceudre.
