XL883 Ignition module calibration changes
The XL883 Sportster calibrations have been changed to improve drivability and
to reduce a slight dip in performance accompanied by a coughing sound heard in
the air cleaner on tip in. (initial roll on, just off idle) The new calibrations will be
available, for dealer installation, in Digital Technician starting with release 14.06
scheduled for delivery during the first week of December.
Note: This is a new update developed since the release of Service Bulletin M-
1162 and is only applicable to 2004-2005 XL883 models produced prior to
12/01/2004. This update should be applied even if the update from M-1162 has
already been performed.
Dealers should install the new calibration when the motorcycle is presented for
service. Dealers should mark the ICM with the addition of a “B� on the part
number label of the ICM to indicate to others that the update has been
completed.
Dealers can submit a warranty claim using labor code 7933 for .2 hours labor
when doing this update on motorcycles that have not been updated. The
condition code will also be 7933.
This update SHOULD NOT be applied to motorcycles that have the Ignition Race
Tuner installed. See page 2 if an Ignition Race Tuner is installed.

If XL883 models with the Ignition Race Tuner installed, are experiencing
undesirable drivability characteristics in the RPM range just off idle, technicians
can try increasing the values highlighted below (shown to be 0 degrees) to a
value of between 3 and 5 degrees of total timing advance. This recommendation
is only a starting point; your particular state of tune may dictate different values.
