I have a brand new unused Techno Research Maximus tuner that uses the Direct Link tuning software for sale. This fits four pin Delphi ECMs. The list below is of the HD's it'll work with.
Touring models 2002-2013
Softail models 2001-2011
XL Sportster models 2007-2013
V-Rod models 2002-2017
Dyna models 2004-2011
Price is $400 shipped to the lower 48 states. This is unmarried, never connected to an ECM.
This has only been out of the box to see that everything was there after I bought it. This includes the programming interface from your laptop to the bike's ECM. A cable from the interface to the ECM and a cable from the interface to the laptop's USB port.
They don't include the software in the package, but I have their web link to download the Direct Link software.
There are many base MAPs within the software. Below are photos of the unit and images from the Direct Link software.
