<h1>ECMLink 101</h1> <div class="level1"> <p> This page is intended to orient the new user to the ECMLink system and, to some extent, ECU tuning concepts in general. If you just received your package and really have no idea where to even start, this is probably the page for you. If you already know how to tune an ECU and already understand basic engine operation and how to use the ECMLink application, then this page is probably not for you. </p> </div> <h2>ECMLink startup</h2> <div class="level2"> <ul> <li class="level1"> <a href="/wiki/doku.php?id=ecmlink101install" class="wikilink1" title="ecmlink101install">Install/powerup/connect</a> - Installing the application and device drivers and powering up for the first time and connecting.</li> <li class="level1"> <a href="/wiki/doku.php?id=ecmlink101initialchecks" class="wikilink1" title="ecmlink101initialchecks">Initial sanity checks</a> - Sanity checking maf comp and fuel tabs; include configuration of BoostEst and AFRatioEst</li> <li class="level1"> datalogging - Information about datalogs; what they contain, how to add items to them, how to view settings from them, etc.</li> <li class="level1"> datalogging tips - things to look for in datalogs that really illustrate problems or suggest a particular course of action</li> <li class="level1"> sample adjustment - walk through in using the TPS adjustment procedure as a simple example of application usage</li> </ul> </div> <h2>General concepts and tips</h2> <div class="level2"> <ul> <li class="level1"> <a href="/wiki/doku.php?id=engineandecu101" class="wikilink1" title="engineandecu101">Engine and ECU 101</a> - You need to have a reasonable understanding of engine operation and ECU tuning concepts.

Try to use some common sense on this one, though. If the suggested values are all over the place or just don't make much sense to you, don't use them.</li> </ul> </div>
