<h1>Aftermarket Sensor Installation</h1> <div class="level1"> <p> You can datalog a number of aftermarket sensors with ECMLink. These primarily include pressure sensors, temperature sensors, and wideband kits. For a complete list of supported sensors, visit the <a href="/wiki/doku.php?id=externalsensorlist" class="wikilink1" title="externalsensorlist">supported sensors</a> page. </p> <p> The following is a high-level overview of the process of connecting an aftermarket sensor to the ECU for logging. Regardless of which sensor is being used, the basic process for installation is almost always the same. </p> <ol> <li class="level1"> You start by installing the sensor according to the manufacturer's installation instructions. This will include running power and ground and whatever else the sensor needs to get.</li> <li class="level1"> Once that's done and the sensor appears to be installed and working properly, you select an <a href="/wiki/doku.php?id=externalsensorinput" class="wikilink1" title="externalsensorinput">available input</a> on the ECU to which you will connect the sensor's output. You disconnect the factory sensor that was providing signal data to the ECU on the selected line and then connect your new sensor's output instead.</li> <li class="level1"> Once that's done, go into the <b>ECU Inputs</b> tab and assign the sensor to an input pin for logging (be <u>sure</u> to hit "Save Pin Assignments" after making a change to the pin assignments). Once you've done that, you can add the sensor to the ECU's list of things to log by pulling up the Captured Values dialog (F10).</li> </ol> </div> <h2>Basics</h2> <div class="level2"> <ul> <li class="level1"> <a href="/wiki/doku.php?id=widebandbasics" class="wikilink1" title="widebandbasics">Wideband basics</a> - The basics behind wiring up an aftermarket wideband kit</li> <li class="level1"> <a href="/wiki/doku.php?id=externalsensorinstall" class="wikilink1" title="externalsensorinstall">Basic installation example</a> - Describes the basic process using a Zeitronix WBO2 installed on a 1G as an example</li> <li class="level1"> <a href="/wiki/doku.php?id=externalsensorinput" class="wikilink1" title="externalsensorinput">Available ECU inputs</a> - A list of available ECU inputs to which you can consider connecting an external sensor</li> <li class="level1"> <a href="/wiki/doku.php?id=externalsensorlist" class="wikilink1" title="externalsensorlist">List of supported sensors</a> - A list of sensors for which the DSMLink application includes display routines</li> <li class="level1"> <a href="/wiki/doku.php?id=ecuwiringinformation" class="wikilink1" title="ecuwiringinformation">ECU wiring information</a> - Pin-outs and MFI circuit schematics for the 1G and 2G DSMs</li> </ul> </div> <h2>Exceptions, special cases and examples</h2> <div class="level2"> <ul> <li class="level1"> <a href="/wiki/doku.php?id=ecuinputdata" class="wikilink1" title="ecuinputdata">Buffering ECU inputs</a> - Some sensors can't properly drive certain inputs on our ECU.
