Several support features are located under the

[Help] menu; some require an internet

A comprehensive Tuning Manual in PDF

format is included on the CD for viewing and
printing from your desktop.

When the SmartLink program is opened, it

will automatically retrieve and open the last map
that was open.

Any time you link to your motorcycle: Read

the map that is installed in the ThunderMax
ECM by selecting

[File] then [Read Module

Maps and Settings] on the SmartLink toolbar.
This will synchronize the map file loaded into the
ThunderMax ECM with the SmartLink software.

2003 FLT/FLHT models: H-D® used 2 different

speedometer calibrations during the extended
2003 model production. Which calibration you
may need is easily identified by checking the
part number on the back of your factory ECM.

20480 is used if the part number

ends in -03, while

4352 is used if the ECM p/n

ends in -02. If your turn signals don’t cancel on
a 2003 model, try the alternate setting.

2007-up Big Twin models: There are two

settings in the [Module Configuration] [Basic
Settings] page that should to be set to the
following to enable the 6


gear indicator light to

Final drive ratio

[87; 84 for 06-07 Dyna®]

Gear 6 Min TPS [40].

Sportster® models: The [Main Relay Loc]

must be set to “1” under the

[Basic Settings]

[Module Configuration] page, or the engine will
not start.

Accel Fuel is be used to tune throttle response

(go to [Module Configuration] [Basic Settings]).

AFR Correction vs. Engine Temperature page

is used to adjust cold start AFR’s. It is active yet
should be used with extreme caution. Any
changes made to this page affects all maps, at
every throttle position, every 256 RPM’s! See
SmartLink Tuning Manual for procedures.

AFR vs. Engine Temperature is active yet at

this time you should be discouraged from
making any changes to this page.

Air/Fuel-TPS @ RPM These pages reflect

desired targets of AFR to throttle position at
every 256 RPM. Example: if you desire a leaner
mixture for added fuel economy then you can
easily make multi-tiered AFR targets at specific
throttle positions and RPM’s that will be learned
during closed loop processing.

During warm-up, the AFR on both cylinders will

be richer than the target AFR at normal
operating temperatures; this is a normal part of
the warm-up map. AutoTune and its targets are
inactive below 200 degrees.

Target air/fuel ratios can be viewed on the

Air/Fuel-TPS @ RPM pages. When these
pages are open, you can view the target AFR by
clicking on a dot and tapping the space bar to
view the target at a specific throttle position for
that RPM. Use arrow keys to raise/lower targets.

Writing new or modified maps to the module

requires the system to be re-initialized (Step 7),
and any existing learned fuel and IAC
adjustments to be cleared (Map Editing, clear).
Linking and editing an existing map within the
module does not require above steps.

System Updates are available through

SmartLink with an internet connection.

Software, Firmware and Map updates can be
downloaded; check frequently for updates.

In-Tank Fuel Filters should be inspected as a

part of routine maintenance. The filter is small
and one bad load of fuel can clog it. The factory
recommended service interval is 25K miles.

Save your edited maps to your hard drive

using the [Save As] command. Document the
changes in [Map Notes] located under [EFI
Maps on the toolbar. These notes are stored
with the saved map; remember to edit them
when making changes for future reference.

Oxygen Sensor Care: Items that can damage

or shorten the life of your sensors:

Leaded fuel – Race fuel
Oil deposits from oil consumption problems
Excessive moisture exposure
Excessive (extreme) heat

There is no warranty on sensors. Replacement
P/N is 309-355.
