How to Identify an EPROM ECU


Oct 15, 2006
Mechanicsburg, Pennsylvania
Here are many links you can use to aid in identifying an EPROM ECU. DO NOT always go by what the sticker says on the case, as it may have been swapped.

95-96 EPROM Check

Once you've identified that you do have an EPROM, you need to check if it has been socketed. The "Socket Check" section on this page will help you do that. This is so you can run an aftermarket EPROM chip (i.e. for ECMlink).

If it is not socketed, you will need to get in touch with ECMTuning to arrange for them to socket your ECU. Or if you are comfortable working on electrical boards like this, you can attempt it yourself. Here's the page with the correct socket info.
