An EMCS Home Programmer gives the user the ability to reprogram their ECU with the latest software updates and to reconfigure their ECU for different preferences or features. To order a home programmer, you must first determine which style of EMCS module you have.

There are three different variations on EMCS boards, EMCS 1 with an "A" connector, EMCS 1 with a "B" connector, and EMCS 2. First determine whether you have an EMCS 1 or EMCS 2 board:

If you have an EMCS 1 board, there are two different connectors on the circuit board itself, "A" and "B".
