Rancho Cucamonga, CA | I understand that if a FC sends a signal to widen the pulse width to richen the mix, the O2 sensor will report it being rich on the next cycle causing the ECU to decrease the amount of fuel, causing the FC to add more and so on and so in a decending conflict loop. That is the problem when thinking in AFRs and not spent gasses. If you can make the ECU think the O2 sensor is at .5v when it may be a little higher, it won't keep trying to compensate for a bad value.
Power Pro is patented by Dobeck, so that is expected. |

. With the initial closed loop VFC Lloyd tried using a fixed value in the 02, and after some real work, and Dyno investigation that I also spent many hours working on. It was decided it was pointless and solved nothing, but on a bike with a smarter ECM I could see where it could be required.
Thing is the more I read about the Cobra. The more I find it to be a repackage of a familiar tool. Problem is that while it is neat. It actually is more limited then the other products made with the same technology. Once again I'll say that I'm not certain, but I won't condom or confirm this thing until I get my hands on one. I have a journalist friend passing a request for a test unit right now. Hopefully I will have an informed proven test in the reasonably near future |

Land O Lakes, FL | I put one on my M109R after much consideration and I can say from experience it works as advertised. It helped my 109 a lot and really smoothed out power delivery while increasing horsepower and keeping the AF ratio safe regardless of mods I added to the bike. We tested this several times with various mod levels and vs other bikes with custom tunes my bike made the same power and had the same curve as similarly equipped custom mapped bikes. This was all done on the same Dyno.
The nice part is you can make changes to the bike without having to go back for remaps. It never made "more" power but it did make the same power at each mod level and seemed to run well no matter the conditions. The bikes AF always stayed in the sweet spot and was always safe which I was very concerned with. It's almost he defacto standard on the other cruisers but for the ease of use and piece of mind I thought it was a great addition. I wouldn't hesitate to get one for my Vision.
Remember custom tuning is only as good as your tuner and the conditions it was tuned in.

Halifax, NS | If you guys want complete control of your fuel ratio - NO MAPS - make your own adjustments then try THIS

I had one on my C90 and they work - With this you decide how rich or lean the bike runs
Check it out

Same hardware as the VFC3, but none of the hours of modification to the underlying mapping to the unit; as Lloydz has put in |
