Dyna Tuners / Fuel Systems

What Is In This Collection

Tuners, throttle bodies, jet kits and fuel injectors, from Dynojet, Daytona Twin Tec, Horsepower Inc, S&S Cycles, Thundermax and Vance & Hines.

Dyna Fitment

Dyna covers '91-'17 - FXD Super Glide, Street Bob, Fat Bob, Wide Glide, Low Rider and Switchback. The Dyna is cable throttle throughout its run, so throttle-by-wire parts do not apply.

Years that change what fits:

• 2006 - the Dyna took the revised cam chest a year before the rest of the range.
• 2017 - the Dyna line ended and was replaced by the M8 Softail.

Why You Need One

A stock ECM is calibrated for the stock intake and exhaust. Open either one up and the mixture goes lean, which costs you the power you just paid for and runs the motor hotter than it should. Tuners come in two broad types: a piggyback that modifies the signal to the stock ECM, and a replacement ECM that takes over entirely. Auto-tune systems correct themselves as you ride using a wideband oxygen sensor; others need a map loaded or a dyno session.
