<h1>EPROM ECU Info</h1> <div class="level1"> <p> ECMLink is released as an EPROM replacement device. That means in order to run ECMLink in your ECU, you must have an EPROM model ECU or you must convert your non-EPROM to EPROM. We have non-EPROM conversion packages for both the 1G DSM and 2G DSM ECUs. You can order these as conversion options directly off the <a href="http://www.ecmtuning.com/product_info.php?cPath=25&products_id=36" class="urlextern" title="http://www.ecmtuning.com/product_info.php?cPath=25&products_id=36" rel="nofollow">Full V3</a> or <a href="http://www.ecmtuning.com/product_info.php?cPath=25&products_id=44" class="urlextern" title="http://www.ecmtuning.com/product_info.php?cPath=25&products_id=44" rel="nofollow">V3Lite</a> product pages (options are listed at the bottom). </p> <p> Also, we do sometimes have a few EPROM ECUs available here for sale with new ECMLink package purchases, so feel free to drop us a line if you want. You can get contact information off our <a href="http://www.ecmtuning.com/contact_us.php" class="urlextern" title="http://www.ecmtuning.com/contact_us.php" rel="nofollow">contacts page</a>. But, really, unless your ECU is blown or you have a 1998-1999 DSM (which we can not convert to EPROM), then it's a lot cheaper to just convert your existing ECU than it is to buy a replacement. </p> <p> Another option if you really need a replacement ECU is to call a few salvage yards. We've found the <a href="http://car-part.com" class="urlextern" title="http://car-part.com" rel="nofollow">car-part.com</a> site to be particularly useful for this. You may need to call around a few places before you find one willing to check the ECU for you, but you can often run up on a pretty good deal ($125-$200). </p> <p> Note: If you can't open the case, you can <a href="/wiki/doku.php?id=pinchecknocase" class="wikilink1" title="pinchecknocase">view the EPROM pins through holes in the bottom of the case.</a> </p> </div> <h1>2G ECU - EPROM CHECK</h1> <div class="level1"> <p> To check for an EPROM inside your 2G ECU, pull the ECU out and check the sticker on top. The sticker should have a part number on it (e.g., MD309947) with some other numbers and a letter in the lower right hand corner. The image below shows this sticker. </p> <p> <a href="/wiki/lib/exe/fetch.php?tok=11e631&media=http%3A%2F%2Fwww.dsmlink.com%2Fimages%2Fphotos%2Feculabel-mid.gif" class="media" title="http://www.dsmlink.com/images/photos/eculabel-mid.gif"><img src="/wiki/lib/exe/fetch.php?tok=11e631&media=http%3A%2F%2Fwww.dsmlink.com%2Fimages%2Fphotos%2Feculabel-mid.gif" class="media" alt="" /></a> </p> <p> If the letter in the lower right hand corner is an "E", then the ECU most likely has an EPROM. To know for sure, you can follow the same steps as outlined below for the 1G ECU. Basically, just open the case and check for the presence of the factory EPROM chip. </p> <p> A list of valid 2G turbo ECU part numbers follow. Note that only the first two marked in <b>bold</b> will <em>likely</em> contain an EPROM. But it's not guaranteed! Please reference this chart if you're not sure about the computer you're sending in. We have had a few cases where folks have shipped us a transmission control unit instead of the engine control unit. </p> <span class='np_break'> </span> <div class="table"><table class="inline"> <tr class="row0"> <td class="col0"> <b>MD312464</b> </td><td class="col1"> <b>MD309947</b> </td><td class="col2"> MD321911 </td><td class="col3"> MD321912 </td><td class="col4"> MD326328 </td> </tr> <tr class="row1"> <td class="col0"> MD335287 </td><td class="col1"> MD346675 </td><td class="col2"> MD346676 </td><td class="col3"> MD359402 </td><td class="col4"> MD359403 </td> </tr> </table> <span class='np_break'> </span> </div> </div> <h1>1G ECU - EPROM Check</h1> <div class="level1"> <p> To check for an EPROM inside a 1G ECU, you really need to open the case to make sure. Open up the case by removing the screws (2 on each "side") holding the top in place. Then remove the top casing half to reveal the circuit board. Compare with the photos below to determine if this ECU has an EPROM or not. </p> <p> <b>1G NON-EPROM NOTE:</b> Keep in mind that even if your ECU is a non-EPROM, it can still be used with ECMLink. We offer a non-EPROM to <a href="http://www.ecmtuning.com/product/noneprom" class="urlextern" title="http://www.ecmtuning.com/product/noneprom" rel="nofollow">EPROM conversion service</a> off our website. This can be ordered separately or with an ECMLink package. When ordered with the ECMLink package, we can offer this conversion at a reduce priced. </p> <p> <a href="/wiki/lib/exe/fetch.php?tok=90da2b&media=http%3A%2F%2Fwww.dsmlink.com%2Fimages%2Fphotos%2Finside1gnoneprom.jpg" class="media" title="http://www.dsmlink.com/images/photos/inside1gnoneprom.jpg"><img src="/wiki/lib/exe/fetch.php?tok=90da2b&media=http%3A%2F%2Fwww.dsmlink.com%2Fimages%2Fphotos%2Finside1gnoneprom.jpg" class="media" title="www.dsmlink.com_images_photos_inside1gnoneprom.jpg" alt="www.dsmlink.com_images_photos_inside1gnoneprom.jpg" /></a> <a href="/wiki/lib/exe/fetch.php?tok=eeede8&media=http%3A%2F%2Fwww.dsmlink.com%2Fimages%2Fphotos%2Finside1geprom.jpg" class="media" title="http://www.dsmlink.com/images/photos/inside1geprom.jpg"><img src="/wiki/lib/exe/fetch.php?tok=eeede8&media=http%3A%2F%2Fwww.dsmlink.com%2Fimages%2Fphotos%2Finside1geprom.jpg" class="media" title="www.dsmlink.com_images_photos_inside1geprom.jpg" alt="www.dsmlink.com_images_photos_inside1geprom.jpg" /></a> </p> <p> A list of valid 1G turbo ECU part numbers follow.

We have had a few cases where folks have shipped us a transmission control unit or a non-turbo model instead of a turbo model engine control unit. Also note that the GVR4 ECU (MD165810 or MD165811) is as close to guaranteed to be an EPROM model as you can get. </p> <p> Also note that only the numbers listed in <b>bold</b> are possible EPROM candidates.
