I have a 2016 Fatboy S, Vance and Hines Staggered Shots stock AC. I am getting ready to do a cams swap, no pistons, no cyl or head work. I am curious if any of you have used a FP3 to select Fueling or Woods cams and what were the results. Did you have noticeable results or did you have to flash the factory ECM, swap tuners to get it tuned properly. I am looking at Woods 777 or Fueling 574 cams fwiw.
Hey Elwood!
Wow, nothing but crickets, I wonder why? I can't believe all the VP3 owners aren't jumping in here and telling you how easy and simple it will be to dial in your new cams? No dyno tuning required, just push the magic button and everything will take care of itself right?. A bunch of new VP3 owner were in here a while back beating there chest about the new technology and how dyno tuners would be out of business. All cool aid drinkers.
Here's some auto tune reality. A cam swap requires a major change in VE to bring the AFR back into the desired range. The stock 02 sensors can read and provide usefull data in the 13.8-15.2 AFR range. The cam swap will move the AFR way outside of this window in many places making afr data unavailable until the VE numbers in the calibration are manually adjusted by a
human. If V+H will provide a base cal that is close the auto tune might have a chance of getting the afrs right in the closed loop area. Here's the problem. Full throttle is out side of closed loop. Along with a dozen other critical adjustments like accell fuel, decell fuel, warm up enrichment, spark knock, spark tables,throttle blade settings, and many other things that all have to be adjusted manually by a
human. The whole point of adding performance parts is to make power. Proper tuning is critical for optimum results. My.02, find a good dyno tuner.
They will reccomend and use TTS Mastertune.
OK VP3 owners! Start the pie throwing!
