So someone asked in my turbo-thread how to use a PCV for a Blackbird. Well i was going to use a Pc3 until i realized that a Pcv would work just fine with some smaller adjustments. The only thing a power commander does as a stand alone unit with no extra accessories is to alter the signal for each injector to make the opening time shorter or longer. This means that any PC will fit any bike as long as you have the right cables. Many new bikes will use a multi-connector for all the fuel injectors, ignition coils and throttle position sensor. To be able to make a PCV work you could cut and paste in this type of harness but it will be a bit more complicated to sort out what colour that does what. The easier way was to search through the manuals for different model specific power commanders until i found one using sort of similar connectors as a blackbird. 4 separate connectors for the injectors and one for the throttle position sensor. The unit i took was to fit a Honda Cbf1000f 06-09. Dynojet part number is DJ16-012. After this you need to cut away these bits from the harness, three of the injector connectors will have a looped cable for the power feed to the pcv. The fourth injector will have the red cable going in to the unit. This is the power feed for the Pcv as the injectors have a constant positive power feed and the negative side is used to control the opening of them.

You will also need connectors and if you want to do it properly buy a crimp-tool instead of trying to fold the small metal clips with a plier. Hx090 male and female connectors bought from Motorcycle Terminals, Connectors, and Wiring Accessories

Tadaa! Finished Honda connectors, and don't forget the small seals!

The grey cable is just as on a pc3 the sensor volt cable and is tapped in to the Tps in exactly the same way. On the Pc3 there could be issues with unstable Tps readings and this was due to the sensor volt ground being tapped directly on the battery negative. Thus using this ground for the sensor the voltage between the sensor ground and remaining power feed on the bike will end up fluctuating causing the Tps percentage to flicker in the Pc3 program. When doing the procedure in a dyno this can make it very hard to get any proper tps reading at low throttle openings making the data useless for compensating in the map. The sensor ground is the black cable with a white stripe on it and is tapped in to the green/orange cable.

Finished Tps connector, i like to be able to disconnect it instead of soldering directly on the tps cables.

As i am currently building on my bike i tapped in a 3p connector at the Tps to be able to also use the +5v feed for sensors to tap in my extra map-sensor. This is connected to a extra wire harness that i have built and thats why i only have a 2p connector on the picture with the plug for the tps to the Pcv. I forgot to take a picture of this though.

Did a Tps and map-sensor calibration and it works magnificent!

I know many here are very technical and have probably already figured this out but this could be done by anyone really that can crimp some connectors and solder some wires. I was searching for any info on this topic before i did this and could not find any so i hope this could help some people here. Updating there Birds with a more modern Pcv that is also expandable with autotune, Wb2 and some more modern displays than the one available for Pc3. :thumb:
