Updating the ECM Calibration
In field updates (or reflashing) are possible with the S3000 ECM using the DST. Always check first to be sure
the ECM has been programmed with the latest calibration before attempting any diagnostic or service repair proce-
dure. Calibration files are supplied in the .s37 file format. These files may be supplied to you by the OEM along
with a password unique to that particular s.37 file. You will need the password to complete the re-programming
procedure. Before re-programming the ECM, shut down any other programs running on your PC including wireless
and e-mail programs. The PC must be dedicated to the re-programming process at this time. Be sure your PC bat-
tery is adequately charged. Failure to follow these instructions may render the ECM not usable in the field.
Under the Tools drop down menu, select Reprogram S3000 Engine Control Unit. Turn ignition power ON.
The S3000 Flash Upgrade Wizard dialog box will appear. Select the Next box.
