<h1>2G Non-EPROM Conversion Process</h1> <div class="level1"> <p> Not to brag or anything, but we do a lot of unique, cool stuff at ECMTuning. Stuff that NOBODY else in the world does. So, yeah, we might be bragging a bit, but there are a few things that really do deserve some special mention. The 2G non-EPROM conversion board is one of those. </p> <p> This is not a simple board with a simple adapter. It's a complex design, complex build and complex installation. And to do all that while charging around $150 is a real challenge. The only other company that used to do anything even remotely similar (TechTom/TechnoSquare) did it in a horrible way and charged $600-$700 to do it. </p> </div> <h2>Initial Non-EPROM Board</h2> <div class="level2"> <p> The following picture shows an original non-EPROM board, ready for modification (click to enlarge). </p> <p> <a href="/wiki/lib/exe/fetch.php?media=noneprom2gbefore.jpg" class="media" title="noneprom2gbefore.jpg"><img src="/wiki/lib/exe/fetch.php?w=296&h=236&tok=dd0e87&media=noneprom2gbefore.jpg" class="medialeft" title="noneprom2gbefore.jpg" alt="noneprom2gbefore.jpg" width="296" height="236" /></a> </p> </div> <h2>CPU Removed</h2> <div class="level2"> <p> The first step is to carefully remove the CPU and make a few other modifications to the ECU's PCB to prepare it for our conversion. The following picture shows a board after this step is complete (click to enlarge). </p> <p> <a href="/wiki/lib/exe/fetch.php?tok=3dac5f&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fforums%2Fecurepair%2Fnoneprom-nocpu.jpg" class="media" title="http://www.ecmtuning.com/images/forums/ecurepair/noneprom-nocpu.jpg"><img src="/wiki/lib/exe/fetch.php?w=350&h=280&tok=41b0da&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fforums%2Fecurepair%2Fnoneprom-nocpu.jpg" class="medialeft" title="www.ecmtuning.com_images_forums_ecurepair_noneprom-nocpu.jpg" alt="www.ecmtuning.com_images_forums_ecurepair_noneprom-nocpu.jpg" width="350" height="280" /></a> </p> </div> <h2>Adapter Plug</h2> <div class="level2"> <p> After the CPU is removed, we have to install an adapter plug in its place. The following picture shows a board after this step is complete (click to enlarge). Note the careful solder work involved on those pins. </p> <p> <a href="/wiki/lib/exe/fetch.php?tok=d966b0&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fforums%2Fecurepair%2Fnoneprom-plug.jpg" class="media" title="http://www.ecmtuning.com/images/forums/ecurepair/noneprom-plug.jpg"><img src="/wiki/lib/exe/fetch.php?w=350&h=280&tok=8d6766&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fforums%2Fecurepair%2Fnoneprom-plug.jpg" class="medialeft" title="www.ecmtuning.com_images_forums_ecurepair_noneprom-plug.jpg" alt="www.ecmtuning.com_images_forums_ecurepair_noneprom-plug.jpg" width="350" height="280" /></a> </p> </div> <h2>Finished Product</h2> <div class="level2"> <p> The final step is to snap our specially designed conversion board into place. The following picture shows the finished result (click to enlarge). </p> <p> <a href="/wiki/lib/exe/fetch.php?tok=615b44&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fforums%2Fecurepair%2Fnoneprom-done.jpg" class="media" title="http://www.ecmtuning.com/images/forums/ecurepair/noneprom-done.jpg"><img src="/wiki/lib/exe/fetch.php?w=350&h=280&tok=e51b1e&media=http%3A%2F%2Fwww.ecmtuning.com%2Fimages%2Fforums%2Fecurepair%2Fnoneprom-done.jpg" class="medialeft" title="www.ecmtuning.com_images_forums_ecurepair_noneprom-done.jpg" alt="www.ecmtuning.com_images_forums_ecurepair_noneprom-done.jpg" width="350" height="280" /></a> </p> </div>
