-====== 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.

-===== Initial Non-EPROM Board ===== 
-The following picture shows an original non-EPROM board, ready for modification (click to enlarge).

- 
-===== CPU Removed ===== 
-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).

-===== 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).
