Although I have no personal knowledge of the part in question, it does work similar to a FP3 Vance & Hines unit. That I do know, and I also understand alot of folks on here think a professional tune is the end all and I used to agree. Every bike I have owned since 2000 has been FI and all were tuned by a qualified person and all worked exceptionally well. Until I bought the current bike. Tired of spending alot of money for tune and got a coupon and found a sale @ Eastern and bought a FP3. I am very satisfied, bike only has a set of Fulsac inserts, otherwise stock. Bike runs cool, revs clean, performance is good and it only took maybe 15 minutes inc reading the instructions. I have a knowledge of tuning and dyno operation, and experience with prior bikes, inc a 110, that were turned as I stated. This bike is fine, I will never have another one tuned, using a dyno and operator as I no longer feel the need for max horsepower, I am satisfied with smooth torque, no decel pop and I just see no reason to have someone spend several hours beating the crap out a bike for a tune. If you make significant changes to your engine such as cam, porting etc that is different. But a basically stock bike, no need.
This technology is more wide spread than V&H and bikes, Edelbrock uses it on there supercharger kits, HP tuning and Hellion on there turbo kits, Bully Dog, Spectra Tuning etc on there Diesels and it works. So in my opinion, be a little open minded. The electronic packaged tuning and associated autotunning of a relatively stock HD is possible and maybe even more predominate in the future. Plus it saves you a crap load of cash. JUST my opinion.
