Zipper Mowers Thunder-Max 309-365 - Manual (Page 5)

Step 8
Before restarting the engine, from toolbar click
[Monitoring] [Show Gauges]. The “Engine Speed”,
“Engine Head Temp”, “IAC Position”, “AFR Front”, AFR
Rear” and “AFR Target” gauges are automatically
formatted and are shown on the screen. Additional
gauges can be created if desired (see SmartLink Tuning
Manual under Help menu), but the above gauges are
most helpful during initial set up. You may select any
gauges that you deem important; if too many are chosen
your screen may appear cluttered.
Step 9
Select the “Monitor” button to active the gauges.
It is located beside the “Link” button and will turn green
when the monitor gauge functions are live. The gauges
will be displayed if they were not already on the screen.
Step 10
Now select the IAC Stops vs. Engine
Temperature page from “IAC Curves” menu within the
tuning tree.
Strike the
spacebar to show the actual values of the tuning block
(use left/right arrow keys to move the block marker).
Make certain that the motorcycle is in neutral and the
engine is cold, and then start the engine. Once the
engine idle is stable after 15- 20 seconds, select the
“IAC-Auto” button (Idle Air Control Auto Adjustment).
Allow the “IAC-Auto” function to run at idle until the
engine head temperature reaches 275 degrees. After
reaching temperature of 275 degrees, the “IAC-Auto”
function automatically shuts off. You can terminate this
function at any time, and re-run it at a later time if you
wish.
Step 11
Unlink the SmartLink software from the ECM,
turn off the ignition switch and remove the
communication cable from the ThunderMax ECM. Use
the ‘Save As’ command to create a folder and save the
map to your hard drive. The motorcycle is now ready to
be ridden. Several riding sessions that allow the engine
to reach normal operating temperature should be
completed. During this process, the IAC virtual stops will
automatically be adjusted to the IAC target values set
within the map’s basic settings. This feature
automatically adjusts how the engine comes back to the
specified idle speed. If the IAC stops are set too low, the
engine will dip below the specified idle speed during
certain transient conditions. If the IAC stops are above
the IAC position, the engine will idle above the idle rpm
specified in the idle speed vs. engine temperature page.
If it determined that these automatic adjustments have
not resulted in satisfactory operation of the engine,
consult the SmartLink Manual (available under the
Help
section of the toolbar), Section 3 (Tuning the
ThunderMax ECM) for further adjustment procedures.
CLOSED LOOP PROCESSING
When equipped with AutoTune, your SmartLink software
will allow you to set Air/Fuel tuning parameters for your
ThunderMax and its installed base map. To set the
AutoTune Limits, go to the toolbar and click
[Configure]
[Close Loop MODULE Settings].
The Closed Loop Configuration dialog page opens; the
right side shows the default MAP settings stored in the
MAP file (settings are applied to the installed base map
during the ‘Closed Loop Format’ conversion performed
by SmartLink), while the left side shows what the module
is currently set to (unadjusted, these settings will mirror
AP’s settings). M
The un-highlighted left ‘MODULE’ side of the page
allows editing of those settings within the MODULE for
tuning purposes, while unaffecting the MAP settings. To
edit module settings, click the
[Link/Read (Module)]
button (left side highlights/active). You can now edit
these settings within the live module should you want to
change any of the settings from the MAP default
settings.
Closed Loop Processing (Module) – Check [ON] to
enable closed loop AutoTune processing. During closed
loop processing, the ThunderMax module processes
feedback from the oxygen sensors to adjust the fuel
