You are looking at a second, and fourth gear roll-on of a stock V-rod. Fully warmed up. Notice that not only is the horsepower different but that the air-fuel graph is also different. Our competition would hope that you don't know this. Because they have RPM based technology. This means both runs are made with 100% throttle and both move through the same RPM range. Tradition map style adjustments can optimize either second or fourth, but not both.
You are forever trying to get the best of both worlds. But as you can see there is a different load placed on the engine in 2nd and 4th due to torque multiplication. The load sensing technology of the TFI adds the proper fuel to both second and fourth gear. Flattening out your fuel delivery curve.
Notice how flat the AIR-FUEL RATIO graph is above. The TFI is reading the different fuel demands that the bike needs in different gears. This is an electronic jetkit(r) as jetkits of the past they modified jet needles, needle jets, slide speed, etc. to flatten out the fuel delivery curve. When you change the main jet you change the fuel from 1st through 6th gear. When you raise the needle up you richen up the acceleration fuel through all engine loads. Dobeck Performance has achieved the ability to interface against the stock multidimensional maps to give you carburetor tuning logic.
