S&S Cycle IST Ignition System for S&S V-Series Engines with Flywheel Machined for Crank Trigger - Manual (Page 10)

b. Crank engine for approximately 5 seconds.
c. Leave the ignition switch on for approximately 5 seconds to allow the ignition system to “learn” the specific motorcycle application for
which it is installed.
d. After performing Steps a-c, switch ignition off and reconnect coil wires to spark plugs mounted in engine.
2. Initial Operating Procedure
a. Initially, the S&S Intelligent Spark Technology Ignition System operates using a standard ignition-timing map that may not be optimum
but is considered safe for most engine configurations. After 3 to 5 hours of operation, with the engine warmed up, the IST Ignition System
will have adjusted the map to create one that is optimized for the particular engine configuration. The IST system will continually adapt to
subsequent changes in riding style, fuel quality, weather conditions and elevation to further optimize the ignition map. For this reason,
recording data using a chassis dynamometer should be measured after the system has had sufficient time to learn the specific engine
parameters.
b. Ride your motorcycle as you normally would during this initial learning period. The IST system will learn and adapt the ignition map
to various conditions as they are encountered – so the more riding you do, the more the system will fine tune itself. Below are some
suggested practices to help the system quickly create the initial optimized timing map:
1. Allow engine to remain at normal operating temperature for at least an hour.
2. Ride up hills and/or inclines.
3. Ride at highway speeds for at least 20 minutes. When road conditions are safe, briefly (1-2 seconds at a time) open the throttle all the
way.
4. Ride through intersections/stretches of road where second and third gear roll-ons are required.
D. Troubleshooting:
Basic Troubleshooting
Below are some suggestions if any problems are encountered with the IST Ignition Module.
1. Problem: Engine cranks but will not start.
Possible solutions:
a. Check that the gas tank is full and that the fuel petcock is turned on.
b. Check that coil wires (plug and harness) have been reinstalled properly.
c. Check that the coil has been reconnected.
2. Problem: Key power-on switch does not seem to work.
Possible solutions:
a. Check that the power relay is properly connected on the underside connector. Raising the tank during installation can pull enough on the
wire harness to disconnect the power relay.
b. Check that the battery has been properly reconnected.
c. Check that the connectors are connected correctly.
Advanced Troubleshooting
The S&S® ignition system features advanced self-diagnostic capabilities. The unit detects operational faults, and stores them as codes in
memory. There are two methods of retrieving trouble codes stored in memory. First, by counting Flash Codes generated by the Check Engine
light (see note) and second, by using a Code Reader (Scantool) connected to the data link connector of the S&S Ignition Wiring Harness. Flash
codes allow the mechanic to access the trouble code information without the use of a separate code reader, but are less specific than codes
retrieved by a code reader. Steps for using both methods follow.
NOTES:
•
Motorcycles that have an existing check engine light will use it to read stored codes. For motorcycles without an OEM check engine light, there
is an LED on the face of the ignition module that functions as a check engine light, and is used to read stored codes.
• Trouble codes are stored in memory for as long as the fault exists, and for 50 on/off cycles of the key after a fault is corrected. A code reader
(Scantool) has code clearing capability, and is the only way to clear trouble codes immediately after a fault has been corrected. If a fault still
exists, a new trouble code will be generated.
