 ====== Non-EPROM Conversion Process ======
 Someone asked us to explain what was involved in the non-EPROM conversion process and I thought it was a good question we hadn't covered before.  This page outlines the basic process.
+This page shows the process on a 1G ECU, but the 2G ECU conversion process is very similar.  The pin spacing is MUCH tighter and harder to work with on the 2G ECU, but the basic idea is the same.

 ===== CPU Removed =====
-The first step is to carefully remove the CPU and make a few other modifications to the board to prepare it for our conversion.  The following picture shows a board after this step is complete (click to enlarge).

+===== Adapter Plug =====
+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.

+===== Finished Product =====
+The final step is to snap our specially designed conversion board into place. The following picture shows the finished result (click to enlarge).
