<h1>ECMLink (V3Lite) Firmware Changelog</h1> <div class="level1"> <p> <a href="http://www.ecmtuning.com/apps/firmwareupgrade" class="urlextern" title="http://www.ecmtuning.com/apps/firmwareupgrade" rel="nofollow">Firmware upgrade page</a> </p> <p> This page is ONLY for the V3Lite package. If you have the full V3 package, you need to refer to the <a href="/wiki/doku.php?id=v3firmwarechangelog" class="wikilink1" title="v3firmwarechangelog">Full V3 Firmware Changelog</a> instead. </p> </div> <h2>3.28.106 (03/10/2014)</h2> <div class="level2"> <ul> <li class="level1"> Added support for a user-editable minimum injector pulsewidth. This value can be used to prevent the ECU from attempting to operate the injector outside of its linear areas of flow. Also added functionality to disable fuel trim lean out when you've already reached the minimum injector pulsewidth. Defining the minimum injector pulsewidth somewhere just below the pulsewidth typically seem at idle on a fully warmed engine seems to help smooth out a number of transitional cases where IPW momentarily dips into non-linear areas of operation as happens sometimes when rolling to a stop with large injectors. If the injectors are large enough, it's even possible to get into a situation where you're operating the injector outside its linear range even at idle! So you may find that you need a minimum IPW so high that your typical idle is at a constant (minimum) pulsewidth.</li> </ul> </div> <h2>3.26.72 (10/09/2013)</h2> <div class="level2"> <ul> <li class="level1"> Added "cranking fuel cut" feature to EVO1-3 chips (was already in other versions). When cranking the engine with the throttle to the floor, ECMLink cuts fuel to provide a way of clearing out a flooded engine. The ECU does need to "see" a low throttle angle some time before cranking or else it will flag the TPS as bad and then disable the cranking fuel cut feature. So floor the throttle only when you're just about to start cranking.</li> <li class="level1"> Reduced the minimum injector pulsewidth in order to support larger injectors at idle.</li> <li class="level1"> Changed cranking fuel cut not to activate the cut unless less than WOT is seen as some point after ECU power-up. This prevents a bad TPS signal from inadvertently triggering cranking fuel cut.</li> </ul> </div> <h2>3.24.152 (04/25/2012)</h2> <div class="level2"> <ul> <li class="level1"> Fixed major bug in upgrade process that could leave some V3 flash modules semi-bricked. </li> </ul> </div> <h2>3.24.143 (04/24/2012)</h2> <div class="level2"> <ul> <li class="level1"> Added functionality to significantly reduce the chances of a sudden <a href="/wiki/doku.php?id=v3settingsreverttodefaults" class="wikilink1" title="v3settingsreverttodefaults">battery reset event</a> from wiping out recent config changes.</li> <li class="level1"> Added functionality to keep laptop application in sync with current configuration settings inside the ECU. This allows for super fast reconnects, but also allows for notification to the user when settings are changed unexpectedly.</li> </ul> </div> <h2>3.20.115 (03/22/2010)</h2> <div class="level2"> <ul> <li class="level1"> Fixes idle bug with 1G ECUs running stock MAF as their Base MAF type.</li> </ul> </div> <h2>3.20.107 (03/16/2010)</h2> <div class="level2"> <ul> <li class="level1"> Extended V3Lite functionality to include RPM-based fuel and timing tabs as well as the MAFComp tab required to use our automated <a href="/wiki/doku.php?id=v3mafadjcombft" class="wikilink1" title="v3mafadjcombft">MAF adjustment tool</a>.</li> </ul> </div> <h2>3.20.52 (01/25/2010)</h2> <div class="level2"> <ul> <li class="level1"> Added support for 1G and 2G DSMs!</li> </ul> </div> <h2>3.19.139 (12/23/2009)</h2> <div class="level2"> <ul> <li class="level1"> Enhanced logging of various bit values (ECU pin inputs, etc.) to increase logging rate when viewing those items.</li> <li class="level1"> Changed logging of LoadFactor to increase log rate.</li> <li class="level1"> Released a new and improved AFRatioEst that makes using this critical log item even easier and more accurate, particularly with larger injectors at idle and even cruise conditions.</li> <li class="level1"> Adjusted MAF edge detection logic to be more accurate.</li> </ul> </div> <h2>3.19.49 (09/17/2009)</h2> <div class="level2"> <ul> <li class="level1"> Added support for extended timing and fuel tables. This increases both the size and resolution of the open loop fuel table and also increases the usable resolution on the timing table.</li> <li class="level1"> Adjusted the stock TmngMaxOct and TmngMinOct tables a bit to remove some of the goofiness defined by the factory on the highest load row.</li> <li class="level1"> To use this release, you MUST download and install at least version 3.19.49 of the <a href="http://www.ecmtuning.com/downloads.php" class="urlextern" title="http://www.ecmtuning.com/downloads.php" rel="nofollow">laptop application</a> first.</li> </ul> </div> <h2>3.19.40 (09/08/2009)</h2> <div class="level2"> <ul> <li class="level1"> Original release. Supports EVO1-3 ECUs. Some details <a href="/wiki/doku.php?id=v3litescreenshots" class="wikilink1" title="v3litescreenshots">here</a>.</li> </ul> </div>
