Whats a power commander and do you have to have one?

Answer 1

The PC is a fuel injection and ignition timing (on some models) adjustment unit that plugs "inline" with the bikes' stock ECU. The PC uses original equipment style connectors so that no splicing or cutting of the harness is required. Most installations take less than 15 minutes, some as little as 5 minutes. Changes are made to the bikes fuel and ignition curves via the PC's onboard microprocessor. Using this technology we are able to offer a large area of adjustment without making any permanent changes to the bikes' ECU (electronic control unit). Removing the PC returns the bike to its previous stock condition. The Power Commander can be ordered preprogrammed with a your choice of several settings, based on the modifications to your bike. The unit also comes complete with software and cable link that allows you to change between different maps or make adjustments to a map file.
Yes I have one on my R1. It's basically a jetting tool for fuel injected motorcycles, like a jet kit for carbed bikes.

Answer 2

a power commander is a device that allows you to control the fuel injection and ignition curves on motorcycles. I use one on my modified Harley and it works a lot better for me than the stock " black box" computer.

Answer 3

It is an aftermarket computer reprogrammer for motorcycles (I don't know if they make models for autos well) that is used to reprogram the ignition curve,advance, and air/fuel ratio for added performance and to compensate for other aftermarket equipment like exhaust pipes, air intakes , etc. You do not need one on a stock bike but they or something similiar are important if changing other items for proper , safe performance.

Answer 4

It's certainly not a requirement, but you may want to look into one if your bike is a dog.
