Configuration Menu Items (Config):

Serial Port - Make sure that you have configured the serial port (Config menu) and that the programming cable is plugged into both the ignition and the computers serial port indicated before programming. The ignition must have power supplied to it during the programming procedure.  To determine available ports click the Detect Ports and select the appropriate port you are attached to.  Newer Laptops do not supply a serial port output and will require a USB to Serial Adapter.

 
Change Distribution Type - Pick whether high voltage spark distribution is by Coil ( requires one dual output coil for each pair of cylinders) or is Distributor based (distributor cap). Distribution can be changed here or by double clicking the Status Box labeled H.V. Distr. at the bottom of the screen.

 
 
Change Optical Encoder/Rotor Position - Location of the pickup sensor, indicating Cam or Crank speed can be changed here or by double clicking the Status Box labeled Optical Encoder/Rotor Pos. at the bottom of the screen.
 
 
 
 
Tach Type - A wide variety of tachometers may be used 1,2,H-D,3,4,6 and 8 cylinder tachometers can be used regardless of the engine type the ignition is configured for. Tach Type represents the type of tachometer that is connected to the ignition. The value represents the number of pulses per cam revolution for four cycle engines. The one and three cylinder tachometers put out the same number of pulses regardless of rotor mount position.
Upgrade Firmware - To upgrade the firmware download the latest or desired version and save to the firmware folder.  Make sure the program cable is plugged into both the computer and the ignition. The ignition must have power supplied to it during the upgrade procedure. Go to Config in the menu and click Upgrade Firmware. Select the .pax file you wish to upgrade to then click on Open. Click OK to begin upgrading the firmware. If you have problems updating the firmware try turning the power to the ignition off and then back on and try again.





 




Adjust Sensor - Sensor #1 and Sensor #2- A combo box drop down list allows up to two sensor inputs to be configured either as an analog or digital sensor.  If a sensor is configured as analog a curve transition voltage value must be entered into a text box.  The text box is not visible if Digital or None is chosen.  Analog transition voltages must be in 0.1 volt increments up to 4.2 volts.  The Sensors can be changed here or by double clicking the Status Box labeled Sensor 1 or Sensor 2 at the bottom of the screen.
Adjust Fallback RPM - Select the amount in RPM's that the engine must decelerate before the previous curve will transition.   The Fallback RPM can be changed here or by double clicking the Status Box labeled Fallback RPM at the bottom of the screen.
