Can someone please let me know what a PCIII is exactly? and what it does. I have read about it a bit but not sure what it does?
thanks

 

Power Commander USBIII
PCIII is a module installed on top of your factory ECU, what it does is to remap the fuel injection system to achieve the best performance. The company provides different maps for different applications, you can also have your bike dyno tuned and get the most out of it. If you don't have a FI bike, you don't really need one.

It actually doesn't remap the fuel injection system. It modifies the stock ECU map. you could look at it as a MAP overlay.

So if you add parts to your Harley that effect the combustion mixture you can adjust the STOCK map with a power commander to the desired Air to Fuel Mixture.

 

yEAH, modify is the word LOL or alter the map

 

If u don't have a fuel injected bike... u don't use one at all. You would adjust your carb.

 

They work good, there are alot to choose from so if you need one do your research.

 

thanks to all for responding...

 

PCIII does not supply power to the stock ecm,It is a new ecm that can be fine tuned on a dyno by some one who knows how to.

 

spend the bucks and get a thundermax and avoid having to find a good dyno tuning person. It does auto tune so you can change things as you want and not have to pay for another dyno tune. the canned maps dont always work and are general settings.
