V4 Spark

Configuration

This program allows changing of the V4 Spark module settings via USB.

The module must be connected to the USB before the configuration program is opened. This can be done with the module on or off the bike (very early OEM box versions with a yellow circuit board must be done on the bike). On OEM box versions, set all the DIP switches to OFF.

This only runs on windows. Older units will need their firmware updated. If the "Read from Module" does not populate the fields with numbers, then you probably have an older firmware.

Model - the module will *not* generate the expected timing advance if this does not match the engine.
Rev-limiter - enter a value 1375-13000 RPM, or 0 to disable. Original big modules (with red plug) have a rev-limiter, small do not.
Dwell Time - Stock is 4.0ms (6.0ms for 700). The module automatically extends the dwell time at lower & cranking RPM's.
Individual COP Dwell - (module must have firmware version "e" or later, or this will not be displayed) check this to reduce the low RPM dwell extention and lower the coil temperature. Allows elemination of the previously called for ballast resistors.
Advance Start @ RPM - when timing begins to advance. Max value is 13000 RPM. Full Advance RPM will be adjusted if advance rate is too high. Note: when reading back from the module, this value may be slightly different than what was saved.
Full Advance @ RPM - when timing reaches full advance. Enter a value from 1375-13000 RPM. Start Advance RPM will be adjusted if advance rate is too high.
Full Advance - degrees Before Top Dead Center. Enter a value between Idle Advance and 37, in 0.5 degree increments. Maximum advance value is limited by the position of pulse generator and front edge of "bump" on starter clutch.
Idle Advance - degrees Before Top Dead Center. This value is fixed and display only. It is set by Application as it is fixed by the position of pulse generator and back edge of "bump" on starter clutch.
Pulse Generator Feedback - display value that is normally 130 +/- 1 when the engine is stopped (fluctuates all around when running). If it is less than 129 or greater than 131, then recommended to check the pulse generator resistance with a meter.

Installing

Download - V4 Config.zip. Uncompress, and run setup.exe located in the Package folder. If you are upgrading from an earlier version, go into windows Add/Remove Programs and unistall the existing one first.

This driver is also needed for Win XP/7/8 - no driver needed for 10. Download and uncompress -

V4 Spark inf J.zip - for firmware version "j" and later

V4 Spark inf.zip - for firmware version "i" and earilier

When connecting the V4spark module for the first time -

Win XP:

Windows gives the "Found New Hardware" wizard
Select "No, not this time" on first screen asking to connect to Windows Update
Select "Install from a list or specific location (Advanced)" on next screen
Select "Search for the best driver in these locations", and "Include this locations in the search".
Browse to select the V4 Spark inf folder you downloaded/uncompressed.
Select "Continue Anyway" to the "not passed windows logo testing" warning

Win 7:

Windows gives the "Installing device driver sofware" notification
Wait for windows to give "No driver found" or select skip, then close
Navigate by clicking: Start Menu->Devices and Printers-> Unspecified: V4-spark->Hardware tab->Properties->Change Settings->Update Driver...
Select "Browse my computer for driver software", browse to select the V4 Spark inf folder you downloaded/uncompressed, and select next
Select "Install this driver software anyway" to the "can't verify the publisher" warning
Windows will install as a USB Communications Port. Close/exit back out.

Win 8(.1):

Older units upgrade to firmware version "j" or later (released 10/06/15)
Installs like Win 7.

Win 10:

Will automatically be recognized. - no driver needed.
