The s100 fits inside the ECU and is compatible with the s200 and s200 ROM files.

If you have a Stage 2, 3 or 4 system and wish to upgrade to a newer system you must upgrade to the s200.  You cannot upgrade to a s100.

Upgrading from the s100 (to a s200)

There is no upgrade path from an s100 to an s200 system. 

ECU jumper J12

With the s100 it is recommended to cut jumper J12 inside the ECU.  For US ECUs this jumper is located near the two vertical sub boards inside the ECU.  For JDM ECUs remove J4 which is located on the top of the circuit board near CN2.  This jumper must be replaced if the ECU is used with a Stage 2/3/4 system.
