System Updates are available through SmartLink with an internet connection. Software, Firmware and Map
updates can be downloaded; dealers, tuners and end users should check frequently for updates.
TMax Control Center provides a snapshot of AutoTuned fuel flow adjustments, RPM time logs in increments of
100 RPM’s, engine temperature logs and diagnostic codes. Valuable information about the condition of your tune
and how you ride. AutoMap, located within the TMax Control Center, feature creates a custom base map based
on AutoTuned fuel flow adjustments. Create a custom base map with just a few clicks!
International (non-US) model notes
– ThunderMax does not support active intake/exhaust functions or Jiffy
stand safety switch.
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.
2007-up 6-Speed 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
th
gear indicator light to function:
Final drive ratio: 06-07 Dyna® [84],
’07 FL, ’07-’10 Softail®, ’08-’11Dyna® [87] Gear 6 Min TPS (all) [40]
AFR Correction vs. Engine Temperature page is used to adjust warm-
up AFR’s. If the engine requires more
fuel during warm-up (start to 200°), use this function to adjust. See SmartLink Tuning Manual for procedures.
AFR vs. Engine Temperature - During warm-up, the AFR on both cylinders will show richer than the target AFR
at operating temperatures; this is a normal part of the warm-up map. No permanent changes to AFR targets and
adjustments are made below 200 degrees. See SmartLink Tuning Manual for applications and procedures.
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 enhance multi-tiered AFR
targets at specific throttle positions and RPM’s that will be learned during riding sessions. 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.
Interrupting 12v power to the module (battery service/replacement) requires system to be re-initialized (Step 7).
Check battery terminal tightness as part of routine service (like during oil changes); avoid stacking accessory
power leads onto main battery cables. If equipped with dual battery post ports, connect accessories separately.
When a new map is installed any existing learned fuel and IAC adjustments need to be cleared (Map Editing,
clear x2). Linking and editing an existing map within the module does not require above steps.
System Updates are available through your software with an internet connection [Configure] [SmartLink
Update]. 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 compromise it. The factory recommended service interval is 25K miles.
Fuel Pressure Should Be Checked during periodic service; this is also the first thing to check should you
experience sudden or gradual decreasing performance. For any EFI system to operate properly, your fuel system
should build and maintain 55-62 PSI of fuel pressure; your dealer can perform this simple test quickly.
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.
