    Marco Polo,
    No doubt you have a beautiful machine with state of the art everything in it. That is what you purchase for the most part when you get a Big Dog Motorcycle. In the X-Wedge beauty of what it is, it is a streamline design build to meet the EPA standards being levied down in 2010 and no one in the Motorcycle industry wants to be hit with big fines for not meeting the stringent EPA standards.
    The bike does tune itself to a certain amount depending how the conditions change but is designed to hit that 14.7 mark and nothing more really. It really focuses that attention in the cruise rpm ranges where the bike is designed to be or running for the most part.
    No OEM dealer uses a wide-band "that I am aware of" because it defeats the purpose of meeting the EPA and allows the bike to make power and run at the 13 and 13.5 range where they need to be to make power.
    A true S&S EFI system "not BDM" does have maps that can be dialed in with their software at a S&S authorized tuning center.
    I will take a look at 121 X-Wedge and see what it is up too.....It will be a great motor and I thing they will start making them in bigger cubic inches to get more grunt to the ground because they can stay in the EPA guidelines. You will feel the power due to the cubic inches..that is a good thing anyway.
    The first echelon S&S VFI modules were not bad and they also did change as you rode them up to 20% of the base map before they would trip you engine light but they did not change the base map at all. It's target was to hit the 14.7 mark too....
    The Power Commanders are good units as well if a piggy back system does not bother you. Simple to use and plenty of maps on their site the owner can drop in. They will even make a map for you if you request it.
    I can see why those with a carburetor love what they have, simple, effective and they are in control...

    Neil,

    Want to upgrade my 07 EFI Bulldog with the Thundermax Auto Tune module. Can you advise the specific Thundermax model you used for your upgrade. Also do you have any pics or guidelines to install the unit. Debating to install myself or have a local Zipper dealer do the install. Not the best wrench in the tool box but I can do some basic work and minor wiring. Any advise?

    So most of these post are from several years ago and most pics and links don't work. Sounds like a great system how did it turn out to date? I'm interested
