147CI Harley Tuning HISTORY Made with Stock ECM (No ThunderMax, No PV, No Impact Wiring Solutions

The game has changed. My 147CI Harley just became the first ever tuned on a factory ECM—no ThunderMax, no Power Vision, no Impact Wiring Solutions, just my stock ECM. This breakthrough could reshape Harley performance forever!!!

Performance tuning is evolving, and Harley riders just witnessed a major milestone. For the first time, a 147CI Harley-Davidson motor has been fully tuned on the factory ECM—unlocking complete access to fuel, timing, VE tables, and more, without relying on ThunderMax, Power Vision, or any external device.

This video documents that breakthrough. You’ll see how an innovative beta software gave Matt at Those Dino Guy the ability to treat the stock ECM like a standalone tuner, while still preserving OEM features like cruise control, knock sensors, and engine management. The result? A historic first step that could redefine how riders approach performance builds.

The journey here was unique: my bike had already been tuned to perfection on ThunderMax by George at All American Cycles, one of the most respected builders in the field. With an Impact tuner left over from a prior build, I was in the rare position to explore alternatives—not because anything was wrong, but because curiosity opened the door to something new.
