SR2 EXTENED REPLAY FIRMWARE - IMPORTANT!

PLEASE READ

Prior to the SR2 upgrade, your GEN3 ECU was configured with “Original Replay” internal data
logging capability (it recorded for up to eighteen (18) seconds). The SR2 upgrade includes the
“Extended Replay” functionality, which increases the number signals recorded and the record
time up to five (5) minutes, based on the sample rate selected.

The “Extended Replay” firmware requires that a new folder be created inside of the BigComm
folder, so that the internal data logging or “Replay” functionality is not affected.

First, create a new folder inside of the BigComm folder and name it SR2_BigComm so that the
file hierarchy is: C:\ProgramFiles\BigStuff\BigComm\SR2_BigComm.
